BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention is directed to systems and methods for identifying screens and screen assemblies used on vibratory separators and shale shakers.
2. Description of Related Art
The prior art discloses a variety of systems and methods for using surface acoustic wave tags or radio frequency identification tags in identifying items, including items used in the oil and gas industry such as drill pipe. (See e.g. U.S. Pat. Nos. 4,698,631; 5,142,128; 5,202,680; 5,360,967; 6,333,699; 6,333,700; 6,347,292; 6,480,811; and U.S. patent applications Ser. No. 10/323,536 filed Dec. 18, 2002; Ser. No. 09/843,998 filed Apr. 27, 2001; Ser. No. 10/047,436 filed Jan. 14, 2002; Ser. No. 10/261,551 filed Sep. 30, 2002; Ser. No. 10/032,114 filed Dec. 21, 2001; and Ser. No. 10/013,255 filed Nov. 5, 2001; all incorporated fully herein for all purposes.) In many of these systems a radio frequency identification tag or “RFIDT” is used on pipe at such a location either interiorly or exteriorly of a pipe, that the RFIDT is exposed to extreme temperatures and conditions downhole in a wellbore. Often an RFIDT so positioned fails and is of no further use. Also, in many instances, an RFIDT so positioned is subjected to damage above ground due to the rigors of handling and manipulation.
The present inventors have realized that, in certain embodiments, substantial usefulness for a tubular identification system can be achieved by divorcing the desire for effective above-ground identification and operation from the goal of downhole accessibility.

SUMMARY OF THE PRESENT INVENTION

The present invention provides, in certain aspects, a screen or screen assembly for a vibratory separator or shale shaker; the screen or screen assembly having one, two, or more energizable identification apparatuses, e.g. RFIDT or SAW tags, the energizable identification apparatuses may be on or within the screen or screen assembly, either within a solid part or in a space within a hollow member, e.g. within a hollow part of a frame.
The present invention, in certain aspects, provides an item, an apparatus, or a tubular, e.g. a piece of drill pipe, with an energizable identification apparatus, e.g. a radio frequency identification tag either affixed exteriorly to the item, apparatus or tubular or in a recess in an end thereof so that the RFIDT is protected from shocks (pressure, impacts, thermal) that may be encountered in a wellbore or during drilling operations. In one particular aspect one or more RFIDT's are covered with heat and/or impact resistant materials on the exterior of an item. In one particular aspect, the present invention discloses systems and methods in which a piece of drill pipe with threaded pin and box ends has one or more circumferential recesses formed in the pin end into which is emplaced one or more radio frequency identification tags each with an integrated circuit and with an antenna encircling the pin end within A recess. The RFIDT (OR RFIDT'S) in a recess is protected by a layer of filler, glue or adhesive, e.g. epoxy material, and/or by a cap ring corresponding to and closing off the recess. Such a cap ring may be made of metal (magnetic; or nonmagnetic, e.g. aluminum, stainless steel, silver, gold, platinum and titanium), plastic, composite, polytetrafluoroethylene, fiberglass, ceramic, and/or cermet. The RFIDT can be, in certain aspects, any known commercially-available read-only or read-write radio frequency identification tag and any suitable known reader system, manual, fixed, and/or automatic may be used to read the RFIDT.
The present invention, in certain aspects, provides an item, apparatus, or tubular, e.g. screen assembly or a piece of drill pipe, with one or more energizable identification apparatuses, e.g. radio frequency identification tags, wrapped in heat and impact resistant materials; in one aspect, located in an area 2-3″ in length beginning ½ from the 18 degree taper of the pin and drill pipe tool joint so that the RFIDT (or RFIDT's) is protected from shocks (pressure, impacts, thermal) that may be encountered on a rig, in a wellbore, or during wellbore (e.g. drilling or casing) operations. In one particular aspect, the present invention discloses systems and methods in which a piece of drill pie with threaded pin and box ends has one or more radio frequency identification tags each with an integrated circuit and with an antenna encircling the pin end upset area located exteriorly on the pipe, e.g. in an area ½″-2½″ from a pin end 18 degree taper. The RFIDT (or RFIDT'S) is protected by wrapping the entire RFIDT and antenna in a heat resistant material wrapped around the circumference of the tube body and held in place by heat resistant glue or adhesive, e.g. epoxy material which encases the RFIDT. This material is covered with a layer of impact resistant material and wrapped with multiple layers of wrapping material such as epoxy bonded wrap material. Preferably this wrapping does not exceed the tool joint OD. The RFIDT can be (as can be any disclosed herein), in certain aspects, any known commercially-available read-only or read-write radio frequency identification tag and any suitable know reader system, manual, fixed, and/or automatic may be used to read the RFIDT. Such installation of RFIDT's can be carried out in the field, in a factory, on a rig, with no machining necessary. Optionally, a metal tag designating a unique serial number of each item, apparatus, or length of drill pipe located under the wrap with the RFIDT(s) insures “Traceability” is never lost due to failure of the RFIDT(s). Replacement of failed RFIDT's can be carried out without leaving a location, eliminating expensive transportation or trucking costs. Optionally the wrap is applied in a distinctive and/or a bright color for easy identification. Determining whether an item, apparatus, or a tubular or a length of drill pipe or a drill pipe string is RFID-tagged or not is visibly noticeable, e.g. from a distance once the RFIDT's are in place. Such wrapping may be used to apply an energizable identification apparatus to a screen assembly.
In certain particular aspects an RFIDT is encased in a mass of material or in a ring of protective material whose shape and configuration corresponds to the shape of the pin end's recess and the ring is either permanently or removably positioned in the recess. Such a ring may be used without or in conjunction with an amount of protective material covering the ring or with a cap ring that protectively covers the RFIDT. Two or more RFIDT's may be used in one recess and/or there may be multiple recesses at different levels. In other aspects a ring is provided which is emplaceable around a member, either a generally cylindrical circular member or a member with some other shape.
With an RFIDT located in a pipe's pin end as described herein, upon makeup of a joint including two such pieces of pipe, an RFIDT in one pipe's pin end is completely surrounded by pipe material—including that of a corresponding pipe's box end—and the RFIDT is sealingly protected from access by materials flowing through the pipe and from materials exterior to the pipe. The mass of pipe material surrounding the enclosed RFIDT also protects it from the temperature extremes of materials within and outside of the pipe.
In other aspects [with or without an RFIDT in a recess] sensible material and/or indicia are located within a recess and, in one aspect, transparent material is placed above the material and/or indicia for visual inspection or monitoring; and, in one aspect, such sensible material and/or indicia are in or on a cap ring.
A pipe with a pin end recess as described herein can be a piece of typical pipe in which the recess is formed, e.g. by machining or with laser apparatus or by drilling; or the pipe can be manufactured with the recess formed integrally thereof. In certain particular aspects, in cross-section a recess has a shape that is square, rectangular, triangular, semi-triangular, circular, semi-circular, trapezoid, dovetail, or rhomboid.
It has also been discovered that the location of an RFIDT or RFIDT's according to the present invention can be accomplished in other items, apparatuses, tubulars and generally tubular apparatuses in addition to drill pipe, or in a member, device, or apparatus that has a cross-section area that permits exterior wrapping of RFIDT(S) or circumferential installation of antenna apparatus including, but not limited to, in or on casing, drill collars, (magnetic or nonmagnetic) pipe, thread protectors, centralizers, stabilizers, control line protectors, mills, plugs (including but not limited to cementing plugs), and risers; and in or on other apparatuses, including, but not limited to, whipstocks, tubular handlers, tubular manipulators, tubular rotators, top drives, tongs, spinners, downhole motors, elevators, spiders, powered mouse holes, and pipe handlers, sucker rods, and drill bits (all which can be made of or have portions of magnetizable metal or nonmagnetizable metal).
In certain aspects the present invention discloses a rig with a rig floor having thereon or embedded therein or positioned therebelow a tag reader system which reads RFIDT's in pipe or other apparatus placed on the rig floor above the tag reader system. All of such rig-floor-based reader systems, manually-operated reader systems, and other fixed reader systems useful in methods and systems according to the present invention may be, in certain aspects, in communication with one or more control systems, e.g. computers, computerized systems, consoles, and/or control system located on the rig, on site, and/or remotely from the rig, either via lines and/or cables or wirelessly. Such system can provide identification, inventory, and quality control functions and, in one aspect, are useful to insure that desired tubulars, and only desired tubulars, go downhole and/or that desired apparatus, and only desired apparatus, is used on the rig. In certain aspects one or more RFIDT's is affixed exteriorly of or positioned in a recess an item, apparatus, or tubular, e.g., in one aspect, in a box end of a tubular. In certain aspects antennas of RFIDT's according to the present invention have a diameter between one quarter inch to ten inches and in particular aspects this range is between two inches and four inches. Such systems can also be used with certain RFIDT's to record on a read-write apparatus therein historical information related to current use of an item, apparatus or of a tubular member; e.g., but not limited to, that this particular item, apparatus, or tubular member is being used at this time in this particular location or string, and/or with particular torque applied thereto by this particular apparatus.
In other aspects, a pipe with a pin end recess described therein has emplaced therein or thereon a member or ring with or without an RFIDT and with sensible indicia, e.g., one or a series of signature cuts, etchings, holes, notches, indentations, alpha and/or numeric characters, raised portion(s) and/or voids, filled in or not with filler material (e.g. but not limited to, epoxy material and/or nonmagnetic or magnetic metal, composite, fiberglass, plastic, ceramic and/or cermet), which indicia are visually identifiable and/or can be sensed by sensing systems (including, but not limited to, systems using ultrasonic sensing, eddy current sensing, optical/laser sensing, and/or microwave sensing). Similarly it is within the scope of the present invention to provide a cap ring (or a ring to be emplaced in a recess) as described herein (either for closing off a recess or for attachment to a pin end which has no such recess) with such indicia which can be sensed visually or with sensing equipment.
It is within the scope of this invention to provide an item, apparatus, or tubular member as described herein exteriorly affixed (RFIDT(s) and/or with a circular recess as described above with energizable identification apparatus other than or in addition to one or more RFIDT'S; including, for example one or more surface acoustic wave tags (“SAW tags”) with its antenna apparatus in the circular apparatus.
What follows are some of, but not all, the objects of this invention. In addition to the specific objects stated below for at least certain preferred embodiments of the invention, other objects and purposes will be readily apparent to one of skill in this art who has the benefit of this invention's teachings and disclosures.

DESCRIPTION OF EMBODIMENTS PREFERRED AT THE TIME OF FILING FOR THIS PATENT

FIGS. 1A-1C show a pin end 10 of a drill pipe according to the present invention which has a sealing shoulder 12 and a threaded end portion 14. A typical flow channel 18 extends through the drill pipe from one end to the other. A recess 20 in the top 16 (as viewed in FIG. 1C) of the pin end 10 extends around the entire circumference of the top 16. This recess 20 is shown with a generally rectangular shape, but it is within the scope of this invention to provide a recess with any desired cross-sectional shape, including, but not limited to, the shapes shown in FIG. 1D. In one aspect an entire drill pipe piece with a pin end 10 is like the tubular shown in FIG. 3A or the drill pipe of FIG. 12B. The recess 20 (as is true for any recess of any embodiment disclosed herein) may be at any depth (as viewed in FIG. 1C) from the end of the pin end and, as shown in FIGS. 1A-1C may, according to the present invention, be located so that no thread is adjacent the recess.
It is within the scope of the present invention to form the recess 20 in a standard piece of drill pipe with a typical machine tool, drill, with a laser apparatus such as a laser cutting apparatus, or with etching apparatus. Alternatively, it is within the scope of the present invention to manufacture a piece of drill pipe (or other tubular) with the recess formed integrally in the pin end (and/or in a box end). The recess as shown in FIG. 1C is about 5 mm wide and 5 mm deep; but it is within the scope of certain embodiments of the present invention to have such a recess that is between 1 mm and 10 mm wide and between 2 mm and 20 mm deep.
A cap ring 22 is installed over the recess 20 which seals the space within the recess 20. This cap ring 22 (as may be any cap ring of any embodiment herein) may be made of any suitable material, including, but not limited to: metal, aluminum, zinc, brass, bronze, steel, stainless steel, iron, silver, gold, platinum, titanium, aluminum alloys, zinc alloys, or carbon steel; composite; plastic, fiberglass, fiber material such as ARAMID™ fiber material; KEVLAR™ or other similar material; ceramic; or cermet. The cap ring 22 may be sealingly installed using glue, adhesive, and/or welding (e.g., but not limited to Tig, Mig, and resistance welding and laser welding processes).
Disposed within the recess 20 beneath the cap ring 22, as shown in FIG. 1C, is an RFIDT device 28 which includes a tag 24 and an antenna 26. The antenna 26 encircles the recess 20 around the pin end's circumference and has two ends, each connected to the tag 24. The RFIDT tag device may be any suitable known device, including, but not limited to the RFID devices commercially available, as in FIG. 2, e.g. from MBBS Company of Switzerland, e.g. its E-Units™ (TAGs) devices e.g., as in FIG. 2. The RFIDT device 28 may be a read-only or a read-write device. It is within the scope of this invention to provide one, two, three or more such devices in a recess 20 (or in any recess of any embodiment herein). Optionally, the RFIDT device (or devices) is eliminated and a recess 20 with a particular varied bottom and/or varied side wall(s) and/or a cap ring with a nonuniform, varied, and/or structured surface or part(s) is used which variation(s) can be sensed and which provide a unique signature for a particular piece of drill pipe (as may be the case for any other embodiment of the present invention). These variations, etc. may be provided by different heights in a recess or different dimensions of projections or protrusions from a recess lower surface or recess side wall surface, by etchings thereon or on a cap ring, by cuts thereon or therein, and/or by a series of notches and/or voids in a recess and/or in a cap ring and/or by sensible indicia. Optionally, instead of the RFIDT device 28 (and for any embodiment herein any RFIDT) a SAW tag may be used and corresponding suitable apparatuses and systems for energizing the SAW tag(s) and reading them.
In certain aspects of the present invention with a recess like the recess 20 as described above, a ring or torus is releasably or permanently installed within the recess with or without a cap ring thereover (like the cap ring 22). Such a ring or torus may have one, two, or more (or no) RFIDT's therein. Such a ring or torus may be installed on any item, device, machine, or apparatus. FIGS. 2A and 2B show a torus 30 installable within a recess, like the recess 20 or any recess as in FIG. 1C, which includes a body 31 with a central opening 31a. An RFIDT 32 is encased on the body 31. The RFIDT 32 has an integrated circuit 33 and an antenna 34 which encircles the body 31. In certain aspects the body 31 (as may be any body of any plug, mass for containing an energizable identification apparatus, torus or ring according to the present invention) is made of metal, plastic, polytetrafluorethylene, fiberglass, composite, ceramic, or of a nonmagnetizable metal. The opening 31 a (as may be any opening of any torus or ring herein) may be any desired diameter. Optionally, or in addition to the RFIDT device 28, and RFIDT device 28 a (or devices 28 a) is affixed exteriorly to the pin end 10 with a multi-layer wrap as described below (see FIGS. 28, 26) (any energizable identification apparatus RFIDT(s) or SAW tag(s) may be used for the RFIDT 28 a).
FIGS. 2C and 2D show a torus 35 which has a central opening 35 a, a body 36 and an RFIDT 37 therein with an antenna 38 that encircles the body 36 and an integrated circuit 39. In one aspect a recess 20 a in a body for receiving a torus 35 has an upper lip 20 b (or inwardly inclined edge or edges as shown in FIG. 2D) and the body 36 is made of resilient material which is sufficiently flexible that the torus 35 may be pushed into the recess 20 a and releasably held therein without adhesives and without a cap ring, although it is within the scope of the present invention to use adhesive and/or a cap ring with a torus 35.
FIG. 2E shows a torus 40 according to the present invention with a body 40 a which is insertable into a recess (like the recess 20, the recess 20 a, or any recess disclosed herein) which has one or more elements 41 therein which serve as strengthening members and/or as members which provide a unique sensible signature for the torus 40 and, therefore, for any pipe or other item employing a torus 40. The torus 40 has a central opening 40 b and may, according to the present invention, also include one, two or more RFIDT's (not shown).
FIGS. 2F and 2G show a torus 44 according to the present invention insertable into any recess disclosed herein which has a body 45, a central opening 44 a, and a series of voids 46 a, 46 b, and 46 c. With such a torus 44 made of metal, the voids 46 a-46 c can be sensed by any sensing apparatus or method disclosed herein and provide a unique sensible signature for the torus 44 and for any item employing such a torus 44. Any torus described herein may have such a series of voids and any such series of voids may, according to the present invention, contain any desired number (one or more) of voids of any desired dimensions. In one particular aspect, a series of voids provides a barcode which is readable by suitable known barcode reading devices. A torus 44 can be used with or without a cap ring. As desired, as is true of any torus according to the present invention, one, two, or more RFIDT's may be used within or on the torus body. Voids may be made by machining, by drilling, by etching, by laser etching, by hardfacing or using a photovoltaic process.
FIG. 2H shows a torus 47 according to the present invention useful in any recess of any embodiment herein which has a series of sensible ridges 48 a-48 f which can be made by adding material to a torus body 49 (such a torus may have visually readable indicia, e.g. alpha ((letter)) and/or numeric characters). Any torus, ring, or cap ring herein may have one or more such ridges and the ridges can have different cross-sections (e.g. as in FIG. 2H) or similar cross-sections and they can be any suitable material, including, but not limited to metal, plastic, epoxy, carbides, and hardfacing. Also, according to the present invention, a cap ring with one or more RFIDT's and/or any other sensible material and/or indicia disclosed herein may be placed around and secured to a tubular's pin end or box end without using a recess.
FIG. 2M shows a cap ring 22 a, like the cap ring 22, but with sensible indicia 22 b-22 f made therein or thereon for sensing by an optical sensing system, an ultrasonic sensing system, an eddy current sensing system, a barcode sensing system, or a microwave sensing system. A cap ring 22 a may be releasably or permanently installed in or over a recess like any recess disclosed herein. The indicia 22 b-22 f may be like any of the indicia or sensible structures disclosed herein.
FIGS. 2I and 2J show a specific cap ring 50 according to the present invention for use with drill pipe having a pin end. The ring 50 has a body with an outer diameter 50 a of 98 mm, a thickness 50 b of 5 mm, and a wall thickness 50 c of 5 mm. FIGS. 2K and 2L show a specific cap ring 51 according to the present invention for use with a drill pipe pin end having an end portion diameter of about four inches. The ring 51 has an outer diameter 51 a of 98 mm, a thickness 51 b of 8 to 10 mm, and a wall thickness 51 c of 3 mm.
It is within the scope of the present invention to provide a tubular having a box end and a pin end (each threaded or not) (e.g. casing, riser, pipe, drill pipe, drill collar, tubing), each end with an RFIDT in a recess therein (as any recess described herein) with or without a cap ring (as any described herein). FIGS. 3A-3C show a generally cylindrical hollow tubular member 480 according to the present invention with a flow channel 480 a therethrough from top to bottom and which has a threaded pin end 481 and a threaded box end 482. The threaded box end 482 has a circumferential recess 483 with an RFIDT 484 therein. The RFIDT has an IC 485 and an antenna 486 which encircles the box end. Optionally, filler material 487 in the recess 483 encases and protects the IC 485 and the antenna 486; and an optional circular cap ring 488 closes off the recess. The RFIDT and its parts and the cap ring may be as any disclosed or referred to herein. Optionally, the tubular member 480 may have a shoulder recess 483 a with an RFIDT 484 a with an IC 485 a and an antenna 486 a. Filler material 487 a (optional) encases the RFIDT 484 a and, optionally, a cap ring 488 a closes off the recess.
The pin end 481 has a circumferential recess 491 in which is disposed an RFIDT 492 with an IC 493 and an antenna 494 around the pin end. As with the box end, filler material and/or a cap ring may be used with the recess 491. Antenna size is related to how easy it is to energize an IC and, therefore, the larger the antenna, the easier [less power needed and/or able to energize at a greater distance] to energize: and, due to the relatively large circumference of some tubulars, energizing end antennas is facilitated.
FIG. 4A shows a system 70 according to the present invention with a rig 60 according to the present invention which has in a rig floor 61 a reading system 65 (shown schematically) for reading one or more RFIDT's in a drill pipe 66 which is to be used in drilling a wellbore. The reading system 65 incorporates one or more known reading apparatuses for reading RFIDT's, including, but not limited to suitable readers as disclosed in the prior art and readers as commercially available from MBBS Co. of Switzerland. The present invention provides improvements of the apparatuses and systems disclosed in U.S. patent application Ser. No. 09/906,957 filed Jul. 16, 2001 and published on Feb. 7, 2002 as Publication No. 2002/0014966. In an improved system 70 according to the present invention a drill pipe 66 (FIG. 4B) is like the drill pipes 16 in U.S. patent application Ser. No. 09/906,957, but the drill pipe 66 has a recess 67 with a torus 68 therein having at least one RFIDT 69 (shown schematically in FIG. 4B) and a cap ring 68 a over the torus 68. The drill pipe 66 may be connected with a tool joint 76 to other similar pieces of drill pipe in a drill string 77 (see FIG. 4A) as in U.S. patent application Ser. No. 09/906,957 (incorporated fully herein) and the systems and apparatuses associated with the system 70 (FIG. 4A and FIG. 4C) operate in a manner similar to that of the systems 10 and the system of FIG. 1B of said patent application. [i) Drill string 77 includes a plurality of drill pipes 66 coupled by a plurality of tool joints 76 and extends through a rotary table 78, and into a wellbore through a bell nipple 73 mounted on top of a blowout preventer stack 72. An identification tag (e.g. an RFIDT) 71 is provided on one or more drilling components, such as illustrated in FIG. 4A, associated with the system 70, or the drill pipe 66. An electromagnetic signal generator system 74 that includes an antenna and a signal generator is positioned proximate to an identification tag, for example just below rotary table 78 as illustrated in FIG. 4A. Electromagnetic signal generator system 74 establishes a communications link with an identification tag 71 to energize the antenna, interrogate it, and to convey information relating to the equipment or drill pipe.
The drilling system 70 includes the rig 60 with supports 83, a swivel 91, which supports the drill string 77, a kelly joint 92, a kelly drive bushing 93, and a spider 79 with an RFIDT sensor and/or reader 79 a. A tool joint 76 is illustrated in FIG. 4A as connecting two drilling components such as drill pipes 66. The identification tag 71 (or the RFIDT 69 read by the system 65) is operated to communicate a response to an incoming electromagnetic signal generated by electromagnetic signal generator system 74 (or by the system 65) that includes information related to the drilling component with the identification tag. The information may be used, for example, to inform an operator of system 70 of a drilling component's identity, age, weaknesses, previous usage or adaptability. According to the teachings of the present invention, this information may be communicated while drill system 70 is in operation. Some or all of the information provided in an identification tag may assist an operator in making a determination of when drilling components need to be replaced, or which drilling components may be used under certain conditions. The electromagnetic signal communicated by an identification tag or RFIDT may provide general inventory management data (such as informing an operator of the drilling components availability on the drilling site, or the drilling component's size, weight, etc.), or any other relevant drilling information associated with the system.
Additional drill string components 84, which are illustrated in FIG. 4A in a racked position, may be coupled to drill pipe 66 and inserted into the well bore, forming a portion of the drill string. One or more of drill string components may also include identification tags or RFIDT's.
FIG. 4C shows typical information that may be included within an identification tag's or RFIDT's, antenna as the antenna cooperates with electromagnetic signal generator 74 and/or the system 65 to transmit an electromagnetic energizing signal 85 to an identification tag 71 (or 69). The electromagnetic signal generators use an antenna to interrogate the RFIDT's for desired information associated with a corresponding pipe or drilling component.
The electromagnetic signal 85 is communicated to an RFIDT that responds to the transmitted electromagnetic signal by returning data or information 86 in an electromagnetic signal form that is received by one of the antennas, and subsequently communicated to a reader 87 which may subsequently process or simply store electromagnetic signal 86. The reader 87 may be handheld, i.e. mobile, or fixed according to particular needs.
The RFIDT's 69 and 71 may be passive (e.g. requiring minimal incident power, for example power density in the approximate range of 15-25 mW/cm²) in order to establish a communications link between an antenna and the RFIDT. “Passive” refers to an identification tag not requiring a battery or any other power source in order to function and to deriving requisite power to transmit an electromagnetic signal from an incoming electromagnetic signal it receives via an antenna. Alternatively, an RFIDT (as may any in any embodiment herein) may include a battery or other suitable power source that would enable an RFIDT to communicate an electromagnetic signal response 86.
Antennas are coupled to reader 87 by any suitable wiring configuration, or alternatively, the two elements may communicate using any other appropriate wireless apparatus and protocol. The reader 87 is coupled to a control system which in one aspect is a computer (or computers) 88 which may include a monitor display and/or printing capabilities for the user. Computer 88 may be optionally coupled to a handheld reader 89 to be used on the rig or remote therefrom. Computer 88 may also be connected to a manual keyboard 89 a or similar input device permitting user entry into computer 88 of items such as drill pipe identity, drill string serial numbers, physical information (such as size, drilling component lengths, weight, age, etc.) well bore inclination, depth intervals, number of drill pipes in the drill string, and suspended loads or weights, for example.
The computer 88 may be coupled to a series of interfaces 90 that may include one or more sensors capable of indicating any number of elements associated with drill rig derrick 83, such as: a block travel characteristic 90 a, a rotation counter characteristic 90 b, a drill string weight 90 c, a heave compensator 90 d, and a blowout preventer (BOP) distance sensor 90 e. A micro-controller may include one or more of these sensors or any other additional information as described in U.S. application Ser. No. 09/906,957. The control system may be or may include a microprocessor based system and/or one or more programmable logic controllers.
A drill pipe 66 with an RFIDT 69 and an RFIDT 71 provides a redundancy feature for identification of the drill pipe 66 so that, in the event one of the RFIDT's fails, the other one which has not failed can still be used to identify the particular drill pipe. This is useful, e.g. when the RFIDT 71, which has relatively more exposure to down hole conditions, fails. Then the RFIDT 69 can still be used to identify the particular piece of drill pipe. It is within the scope of the present invention for any item according to the present invention to have two (or more RFIDT's like the RFIDT 69 and the RFIDT 71. Optionally, or in addition to the RFIDT 69, an RFIDT 69 a (or RFIDT's 69 a) may be affixed exteriorly of the pipe 66 with wrap material 69 b (as described below, e.g. as in FIGS. 25-32).
FIGS. 5A-5D present improvements according to the present invention of prior art systems and apparatuses in U.S. Pat. No. 6,480,811 B2 issued Nov. 12, 2002 (incorporated fully herein for all purposes). FIG. 5B shows schematically and partially a drill pipe 91 with an RFIDT 92 (like the identifier assemblies 12, U.S. Pat. No. 6,604,063 B2 or like any RFIDT disclosed herein and with an RFIDT 99, (as any RFIDT disclosed herein in a drill pipe's pin end). According to the present invention any item (e.g. a screen) or any oilfield equipment disclosed in U.S. Pat. No. 6,604,063 B2 may have one, two (or more) RFIDT's (e.g., on the item; or one in an end, one in a side, e.g. as shown in FIG. 5B).
FIGS. 5A, 5C and 5D show an oilfield equipment identifying apparatus 100 according to the present invention for use with pipe or equipment as in FIG. 5B with two (or more) RFIDT's on respective pieces 114 of oilfield equipment. The RFIDT's may be any disclosed or referred to herein and those not mounted in a recess according to the present invention may be as disclosed in U.S. Pat. No. 6,480,811 B2 indicated by the reference numerals 112 a and 112 b on pieces of equipment 114 a and 114 b with RFIDT's in recesses according to the present invention shown schematically and indicated by reference numerals 109 a, 109 b; and/or one or more RFIDT's may be affixed exteriorly (see e.g., FIGS. 25, 26) to either piece 114 of oilfield equipment. Each of the identifier assemblies 112 and RFIDT's like 109 a, 109 b are capable of transmitting a unique identification code for each piece of pipe or oilfield equipment. The piece of equipment 114 may be a screen or shaker.
The oilfield equipment identifying apparatus 100 with a reader 118 is capable of reading each of the identifier assemblies and RFIDT's. The reader 118 includes a hand-held wand 120, which communicates with a portable computer 122 via a signal path 124. In one embodiment, each identifier assembly 112 includes a passive circuit as described in detail in U.S. Pat. No. 5,142,128 (fully incorporated herein for all purposes) and the reader 118 can be constructed and operated in a manner as set forth in said patent or may be any other reader or reader system disclosed or referred to herein.
In use, the wand 120 of the reader 118 is positioned near a particular one of the identifier assemblies 112 or RFIDT's. A unique identification code is transmitted from the identifier assembly or RFIDT to the wand 120 via a signal path 126 which can be an airwave communication system. Upon receipt of the unique identification code, the wand 120 transmits the unique identification code to the portable computer 122 via the signal path 124. The portable computer 122 receives the unique identification code transmitted by the wand 120 and then decodes the unique identification code, identifying a particular one of the identifier assemblies 112 or RFIDT's and then transmitting (optionally in real time or in batch mode) the code to a central computer (or computers) 132 via a signal path 134. The signal path 134 can be a cable or airwave transmission system.
FIG. 5C shows an embodiment of an oilfield equipment identifying apparatus 100 a according to the present invention which includes a plurality of the identifier assemblies 112 and/or RFIDT's 109 which are mounted on respective pieces 114 of pipe or oilfield equipment as described above. The oilfield equipment identifying apparatus includes a reader 152, which communicates with the central computer 132. The central computer 132 contains an oilfield equipment database (which in certain aspects, can function as the oilfield equipment database set forth in U.S. Pat. No. 5,142,128). In one aspect the oilfield equipment database in the central computer 132 may function as described in U.S. Pat. No. 5,142,128. In one aspect the oilfield equipment identifying apparatus 100 a is utilized in reading the identifier assemblies 112 (and/or RFIDT's 109) on various pieces 114 of pipe or oilfield equipment located on a rig floor 151 of an oil drilling rig.
The reader 152 includes a hand-held wand 156 (but a fixed reader apparatus may be used). The hand-held wand 156 is constructed in a similar manner as the hand-held wand 120 described above. The wand 156 may be manually operable and individually mobile. The hand-held wand 156 is attached to a storage box 158 via a signal path 160, which may be a cable having a desired length. Storage box 158 is positioned on the rig floor 151 and serves as a receptacle to receive the hand-held wand 156 and the signal path 160 when the hand-held wand 156 is not in use.
An electronic conversion package 162 communicates with a connector on the storage box 158 via signal path 164, which may be an airway or a cable communication system so that the electronic conversion package 162 receives the signals indicative of the identification code stored in the identifier assemblies 112 and/or RFIDT's, which are read by the hand-held wand 156. In response to receiving such signal, the electronic conversion package 162 converts the signal into a format which can be communicated an appreciable distance therefrom. The converted signal is then output by the electronic conversion package 162 to a buss 166 via a signal path 168. The buss 166, which is connected to a drilling rig local area network and/or a programmable logic controller (not shown) in a well-known manner, receives the converted signal output by the electronic conversion package 162.
The central computer 132 includes an interface unit 170. The interface 170 communicates with the central computer 132 via a signal path 172 or other serial device, or a parallel port. The interface unit 170 may also communicates with the buss 166 via a signal path 173. The interface unit 170 receives the signal, which is indicative of the unique identification codes and/or information read by the hand-held wand 156, from the buss 166, and a signal from a drilling monitoring device 174 via a signal path 176. The drilling monitoring device 174 communicates with at least a portion of a drilling device 178 (FIG. 5D) via a signal path 179. The drilling device 178 can be supported by the rig floor 151, or by the drilling rig. The drilling device 178 can be any drilling device which is utilized to turn pieces 114 of oilfield equipment, such as drill pipe, casing (in casing drilling operations) or a drill bit to drill a well bore. For example, but not by way of limitation, the drilling device 178 can be a rotary table supported by the rig floor 151, or a top mounted drive (“top drive”) supported by the drilling rig, or a downhole mud motor suspended by the drill string and supported by the drilling rig. Optionally, the drilling device 178 has at least one RFIDT 178 a therein or t hereon and an RFIDT reader 178 b therein or thereon. The RFIDT reader 178 a is interconnected with the other systems as is the reader 152, e.g. via the signal path 173 as indicated by the dotted line 173 a.
The drilling monitoring device 174 monitors the drilling device 178 so as to determine when the piece 114 or pieces 114 of oilfield equipment in the drill string are in a rotating condition or a non-rotating condition. The drilling monitoring device 174 outputs a signal to the interface unit 170 via the signal path 176, the signal being indicative of whether the piece(s) 114 of oilfield equipment are in the rotating or the non-rotating condition. The central computer 132 may be loaded with a pipe and identification program in its oilfield equipment database which receives and automatically utilizes the signal received by the interface unit 170 from the signal path 176 to monitor, on an individualized basis, the rotating and non-rotating hours of each piece 114 of oilfield equipment in the drill string.
For example, when the drilling device 178 is a downhole mud motor (which selectively rotates the drill string's drill bit while the drill string's pipe remains stationary), the central computer 132 logs the non-rotating usage of each piece 114 of the drill string's pipe. In the case where the drilling device 178 is the downhole mud motor, the central computer 132 has stored therein a reference indicating that the drilling device 178 is the downhole mud motor so that the central computer 132 accurately logs the non-rotating usage of each piece 114 of oilfield equipment included in the drill string that suspends the drilling device 178.
FIG. 5D shows a system 250 according to the present invention for rotating pieces of drill pipe 114 which have at least one identifier assembly 112 and/or one RFIDT in a pin end (or box end, or both) recess according to the present invention to connect a pin connection 252 of the piece 114 to a box connection 254 of an adjacently disposed piece 114 in a well known manner. Each piece 114 may have an RFIDT in its pin end and/or box end. The system 250 includes a reader system 250 a (shown schematically) for reading the RFIDT in the pin end recess prior to makeup of a joint. The apparatus 250 can be, for example, but not by way of limitation, an Iron Roughneck, an ST-80 Iron Roughneck, or an AR 5000 Automated Iron Roughneck from Varco International and/or apparatus as disclosed in U.S. Pat. Nos. 4,603,464; 4,348,920; and 4,765,401. The reader system 250 a may be located at any appropriate location on or in the apparatus 250.
The apparatus 250 is supported on wheels 256 which engage tracks (not shown) positioned on the rig floor 151 for moving the apparatus 250 towards and away from the well bore. Formed on an upper end of the apparatus 250 is a pipe spinner assembly 258 (or tong or rotating device) for selectively engaging and turning the piece 114 to connect the pin connection 252 to the box connection 254. Optionally the assembly 258 has an RFIDT reader 258 a. An optional funnel-shaped mudguard 260 can be disposed below the pipe spinner assembly 258. The mudguard 260 defines a mudguard bore 262, which is sized and adapted so as to receive the piece 114 of oilfield equipment therethrough. The apparatus 250 also may include a tong or a torque assembly or torque wrench 263 disposed below the pipe spinner assembly 258. An opening 264 is formed through the mudguard 260 and communicates with a mudguard bore 262. Optionally an oilfield equipment identifying apparatus 110 includes a fixed mount reader 266 for automating the reading of the RFIDT's and of the identifier assemblies 112, rather than the hand-held wand 156. In one embodiment a flange 268 is located substantially adjacent to the opening 264 so as to position the fixed mount reader 266 through the opening 264 whereby the fixed mount reader 266 is located adjacent to the piece 114 of oilfield equipment when the piece 114 of oilfield equipment is moved and is being spun by the pipe spinner assembly 258. The reader(s) of the apparatus 250 are interconnected with an in communication with suitable control apparatus, e.g. as any disclosed herein. In certain aspects, the fixed mount reader 266 can be located on the apparatus 250 below the pipe spinner assembly 258 and above the torque assembly or torque wrench 263, or within or on the spinner assembly 258; or within or on the torque wrench 263.
The prior art discloses a variety of tubular members including, but not limited to casing, pipe, risers, and tubing, around which are emplaced a variety of encompassing items, e.g., but not limited to centralizers, stabilizers, and buoyant members. According to the present invention these items are provided with one or more RFIDT's with antenna(s) within and encircling the item and with a body or relatively massive part thereof protecting the RFIDT. FIG. 6 shows schematically a tubular member 190 with an encompassing item 192 having therein an RFIDT 194 (like any disclosed or referred to herein as may be the case for all RFIDT's mentioned herein) with an IC (integrated circuit) or microchip 196 to which is attached an antenna 198 which encircles the tubular member 190 (which is generally cylindrical and hollow with a flow channel therethrough from one end to the other or which is solid) and with which the IC 196 can be energized for reading and/or for writing thereto. In one aspect the RFIDT 194 is located midway between exterior and interior surfaces of the encompassing item 192; while in other aspects it is nearer to one or these surfaces than the other. The encompassing item may be made of any material mentioned or referred to herein. The RFIDT 194 is shown midway between a top and a bottom (as viewed in FIG. 6) of the encompassing item 192; but it is within the scope of this invention to locate the RFIDT at any desired level of the encompassing item 192. Although the encompassing item 192 is shown with generally uniform dimensions, it is within the scope of the present invention for the encompassing item to have one or more portions thicker than others; and, in one particular aspect, the RFIDT (or the IC 196 or the antenna 198) is located in the thicker portion(s). In certain particular aspects the encompassing item is a centralizer, stabilizer, or protector. Optionally, or in addition to the RFIDT 194, one or more RFIDT's 194 a in wrap material 194 b may be affixed exteriorly (see e.g., FIGS. 25, 26) of the member 190 and/or of the encompassing item 192.
FIG. 7A shows a buoyant drill pipe 200 which is similar to such pipes as disclosed in U.S. Pat. No. 6,443,244 (incorporated fully herein for all purposes), but which, as shown in FIG. 7A, has improvements according to the present invention. The drill pipe 200 has a pin end 202 and a box end 204 at ends of a hollow tubular body 206 having a flow channel (not shown) therethrough. A buoyant element 210 encompasses the tubular body 206. Within the buoyant element 210 is at least one RFIDT 208 which may be like and be located as the RFIDT 198, FIG. 6. As shown in FIG. 7B, in one aspect the buoyant member 210 has two halves which are emplaced around the tubular body 206 and then secured together. In such an embodiment either one or both ends of an antenna 201 are releasably connectible to an IC 203 of an RFIDT 208 or two parts of the antenna 201 itself are releasably connectible. As shown in FIG. 7B, antenna parts 201 a and 201 b are releasably connected together, e.g. with connector apparatus 201 c, and an end of the antenna part 201 b is releasably connected to the IC 203. Alternatively an optional location provides an RFIDT that is entirely within one half of the buoyant member 210, e.g. like the optional RFIDT 208 a shown in FIG. 7A. The pin end 202 may have any RFIDT therein and/or cap ring according to the present invention as disclosed herein. The two halves of the buoyant member may be held together by adhesive, any known suitable locking mechanism, or any known suitable latch mechanism (as may be any two part ring or item herein according to the present invention).
It is within the scope of the present invention to provide a stabilizer as is used in oil and gas wellbore operations with one or more RFIDT's. FIGS. 8A and 8B show a stabilizer 220 according to the present invention which is like the stabilizers disclosed in U.S. Pat. No. 4,384,626 (incorporated fully herein for all purposes) but which has improvements according to the present invention. An RFIDT 222 (like any disclosed or referred to herein) is embedded within a stabilizer body 224 with an IC 223 in a relatively thicker portion 221 of the body 224 and an antenna 225 that is within and encircles part of the body 224. Parts 225 a and 225 b of the antenna 225 are connected together with a connector 226. The stabilizer 220 may, optionally, have a recess at either end with an RFIDT therein as described herein according to the present invention. Optionally, the stabilizer 220 may have one or more RFIDT's located as are the RFIDT's in FIGS. 6 and 7A.

FIG. 12A shows a system 400 according to the present invention which has a rig 410 that includes a vertical derrick or mast 412 having a crown block 414 at its upper end and a horizontal rig floor 416 at its lower end. Drill line 418 is fixed to deadline anchor 420, which is commonly provided with hook load sensor 421, and extends upwardly to crown block 414 having a plurality of sheaves (not shown). From block 414, drill line 418 extends downwardly to traveling block 422 that similarly includes a plurality of sheaves (not shown). Drill line 418 extends back and forth between the sheaves of crown block 414 and the sheaves of traveling block 422, then extends downwardly from crown block 414 to drawworks 424 having rotating drum 426 upon which drill line 418 is wrapped in layers. The rotation of drum 426 causes drill line 418 to be taken in or out, which raises or lowers traveling block 422 as required. Drawworks 424 may be provided with a sensor 427 which monitors the rotation of drum 426. Alternatively, sensor 427 may be located in crown block 414 to monitor the rotation of one or more of the sheaves therein. Hook 428 and any elevator 430 is attached to traveling block 422. Hook 428 is used to attach kelly 432 to traveling block 422 during drilling operations, and elevators 430 are used to attach drill string 434 to traveling block 422 during tripping operations. Shown schematically the elevator 430 has an RFIDT reader 431 (which may be any reader disclosed or referred to herein and which is interconnected with and in communication with suitable control apparatus, e.g. as any disclosed herein, as is the case for reader 439 and a reader 444). Drill string 434 is made up of a plurality of individual drill pipe pieces, a grouping of which are typically stored within mast 412 as joints 435 (singles, doubles, or triples) in a pipe rack. Drill string 434 extends down into wellbore 436 and terminates at its lower end with bottom hole assembly (BHA) 437 that typically includes a drill bit, several heavy drilling collars, and instrumentation devices commonly referred to as measurement-while-drilling (MWD) or logging-while-drilling (LWD) tools. A mouse hole 438, which may have a spring at the bottom thereof, extends through and below rig floor 416 and serves the purpose of storing next pipe 440 to be attached to the drill string 434. With drill pipe according to the present invention having an RFIDT 448 in a pin end 442, an RFIDT reader apparatus 439 at the bottom of the mouse hole 438 can energize an antenna of the RFIDT 448 and identify the drill pipe 440. Optionally, if the drill pipe 440 has an RFIDT in a box end 443, an RFIDT reader apparatus can energize an antenna in the RFIDT 446 and identify the drill pipe 440. Optionally, the drill bit 437 has at least one RFIDT 437 a (any disclosed herein) (shown schematically). Optionally, or in addition to the RFIDT 448, the drill pipe 440 has one or more RFIDT's 448 a affixed exteriorly to the drill pipe 440 (see, e.g., FIGS. 25, 26) under wrap layers 448 b.
During a drilling operation, power rotating means (not shown) rotates a rotary table (not shown) having rotary bushing 442 releasably attached thereto located on rig floor 416. Kelly 432, which passes through rotary bushing 442 and is free to move vertically therein, is rotated by the rotary table and rotates drill string 434 and BHA 437 attached thereto. During the drilling operation, after kelly 432 has reached its lowest point commonly referred to as the “kelly down” position, the new drill pipe 440 in the mouse hole 438 is added to the drill string 434 by reeling in drill line 418 onto rotating drum 426 until traveling block 422 raises kelly 432 and the top portion of drill string 434 above rig floor 416. Slips 445, which may be manual or hydraulic, are placed around the top portion of drill string 434 and into the rotary table such that a slight lowering of traveling block 422 causes slips 445 to be firmly wedged between drill string 434 and the rotary table. At this time, drill string 434 is “in-slips” since its weight is supported thereby as opposed to when the weight is supported by traveling block 422, or “out-of-slips”. Once drill string 434 is in-slips, kelly 432 is disconnected from string 434 and moved over to and secured to new pipe 440 in mouse hole 438. New pipe 440 is then hoisted out of mouse hole 438 by raising travelling block 422, and attached to drill string 434. Traveling block 422 is then slightly raised which allows slips 445 to be removed from the rotary table. Traveling block 422 is then lowered and drilling resumed. “Tripping-out” is the process where some or all of drill string 434 is removed from wellbore 436. In a trip-out, kelly 432 is disconnected from drill string 434, set aside, and detached from hook 428. Elevators 430 are then lowered and used to grasp the uppermost pipe of drill string 434 extending above rig floor 416. Drawworks 424 reel in drill line 418 which hoists drill string 434 until the section of drill string 434 (usually a “triple”) to be removed is suspended above rig floor 416. String 434 is then placed in-slips, and the section removed and stored in the pipe rack. “Tripping-in” is the process where some or all of drill string 434 is replaced in wellbore 436 and is basically the opposite of tripping out. In some drilling rigs, rotating the drill string is accomplished by a device commonly referred to as a “top drive” (not shown). This device is fixed to hook 428 and replaces kelly 432, rotary bushing 442, and the rotary table. Pipe added to drill string 434 is connected to the bottom of the top drive. As with rotary table drives, additional pipe may either come from mouse hole 438 in singles, or from the pipe racks as singles, doubles, or triples. Optionally, drilling is accomplished with a downhole motor system 434 a which has at least one RFIDT 434 b (shown schematically in FIG. 12A).
As shown in FIG. 12B, the reader apparatus 439 is in communication with a control apparatus 449 (e.g. any computerized or PLC system referred to or disclosed herein) which selectively controls the reader apparatus 439, receives signals from it and, in certain aspects, processes those signals and transmits them to other computing and/or control apparatus. Similarly when the optional reader apparatus 444 is used, it also is in communication with the control apparatus 449 and is controlled thereby. With a reader at the pin end and a reader at the box end, the length of the piece of drill pipe be determined and/or its passage beyond a certain point. In one aspect the reader apparatus 439 is deleted and the reader apparatus 444 reads the RFIDT (or RFIDT's) in and/or on the drill pipe 440 as the drill pipe 440 passes by the reader apparatus 444 as the drill pipe 440 is either lowered into the mouse hole 438 or raised out of it. The reader apparatus 444 may be located on or underneath the rig floor 416. It is within the scope of the present invention to use a reader apparatus 439 and/or a reader apparatus 444 in association with any system's mouse hole or rat hole (e.g., but not limited to, systems as disclosed in U.S. Pat. Nos. 5,107,705; 4,610,315; and in the prior art cited therein), and with so-called “mouse hole sleeves” and mouse hole scabbards” as disclosed in, e.g. U.S. Pat. Nos. 5,351,767; 4,834,604; and in the prior art references cited in these two patents.

An RFIDT 696 (like any disclosed herein) has an antenna 697 encircling and within a bonnet 680 with an IC 698. An RFIDT 684 (like any disclosed herein) has an antenna 685 encircling and within a flange 689 of the side outlet 682, with an IC 686. Optionally, or in addition to the other RFIDT's at least one RFIDT 690 a is affixed exteriorly to the blowout preventer 670 under wrap layers 690 b (see, e.g., FIGS. 25, 26) and/or at least one RFIDT 690 c is affixed exteriorly to the blowout preventer 270 under wrap layers 690 d (see, e.g., FIGS. 25, 26).
FIGS. 25 and 26 show a tool joint 700 according to the present invention with RFIDT apparatus 720 according to the present invention applied exteriorly thereto. The tool joint 700 has a pin end 702 with a threaded pin 704, a joint body portion 706, an upset area 707 and a tube body portion 708. The joint body portion 706 has a larger OD than the tube body portion 708. The “WELDLINE’ is an area in which the tool joint is welded (e.g. inertia welded) by the manufacturer to the upset area.
Although RFIDT's encased in a non-conductor or otherwise enclosed or protected can be emplaced directly on a tubular (or other item or apparatus according to the present invention), as shown in FIGS. 25 and 26 the RFIDT's to be applied to the tool joint 700 are first enclosed within non-conducting material, e.g. any suitable heat-resistant material, e.g., but not limited to, RYTON™ fabric membrane wrapping material, prior to emplacing them on the tool joint 700. In one particular aspect, one, two, three, or four wraps, folds, or layers of commercially available RYT-WRAP™ material commercially from Tuboscope, Inc. a related company of the owner of the present invention is used which, in one particular aspect, includes three layers of RYT-WRAP™ fabric membrane material adhered together and encased in epoxy. As shown, three RFIDT's 720 are wrapped three times in the RYT-WRAP™ material 722 so that no part of any of them will contact the metal of the tool joint 700. In one aspect such a wrapping of RYT-WRAPM material includes RYTON™ fabric membrane material with cured epoxy wrapped around a tubular body (initially the material is saturated in place with liquid epoxy that is allowed to cure).
Prior to emplacing the wrapped RFIDT's 720 on the tool joint 700, the area to which they are to be affixed is, preferably, cleaned using suitable cleaning materials, by buffing, and/or by sandblasting as shown in FIG. 27. Any desired number of RFIDT's 720 may be used. As shown in FIG. 29A, in this embodiment three RFIDT's 720 are equally spaced apart around the exterior of the tool joint 700.
According to the present invention, RFIDT's may be applied exteriorly to any item, apparatus, or tubular at any exterior location thereon with any or all of the layers and/or wraps disclosed herein. In the particular tool joint 700 as disclosed in FIG. 25, the RFIDT's 720 are applied about two to three inches from a thirty-five degree taper 709 of the joint body portion 706 to reduce the likelihood of the RFIDT's contacting other items, handling tools, grippers, or structures that may contact the portion 706.
Optionally, as shown in FIG. 26, either in the initial layers or wraps which enclose the RFIDT's 720 or in any other layer or wrap, an identification tag 724 is included with the RFIDT's, either a single such tag or one tag for each RFIDT. In one aspect the tag(s) 724 are plastic or fiberglass. In another aspect the tag(s) 724 are metal, e.g. steel, stainless steel, aluminum, aluminum alloy, zinc, zinc alloy, bronze, or brass. If metal is used, the tag(s) 724 are not in contact with an RFIDT.
As shown in FIG. 28, an adhesive may be applied to the tool joint 700 to assist in securing a layer 723, “FOLDED MEMBRANE,” (e.g., a double layer of RYT-WRAP™ wrap material.
As shown in FIG. 29, the three RFIDT's 720 are emplaced on the layer 723 and, optionally, the identification tag or tags 724.
Optionally, as shown in FIG. 30, part 723 a of the layer 723 is folded over to cover the RFIDT's 720 and the tag(s) 724. If this folding is done, no adhesive is applied to the tool joint under the portion of the layer 723 which is to be folded over. Optionally, prior to folding adhesive is applied on top of the portion of the layer 723 to be folded over. Optionally, prior to folding the part 723 a over on the RFIDT's 720 and the tag(s) 724 an adhesive (e.g. two part epoxy) is applied over the RFIDT's 720 and over the tag(s) 724.
After allowing the structure of layer 723 a as shown in FIG. 30 to dry (e.g., for forty minutes to one hour), as shown in FIG. 31 the folded layer 723 with the RFIDT's 720 and tag(s) 724 is, optionally, wrapped in a layer 726 of heat shrink material and/or impact resistant material (heat resistant material may also be impact resistant). In one particular optional aspect, commercially available RAYCHEM™ heat shrink material or commercially available RCANUSA™ heat shrink material is used, centered over the folded layer 723, with, preferably, a small end-to-end overlap to enhance secure bonding as the material is heated.
As shown in FIG. 32, optionally, the layer 726 is wrapped with layers 728 of material (e.g. RYT-WRAP™ material) (e.g. with two to five layers). In one particular aspect the layer(s) 728 completely cover the layer 726 and extend for one-half inch on both extremities of the layer 726. Preferably, the final wrap layer of the layers 728 does not exceed the OD of the joint body portion 706 so that movement of and handling of the tool joint 700 is not impeded.
Curing can be done in ambient temperature and/or with fan-assisted dryers.
Any known wave energizable apparatus may be substituted for any RFIDT herein.

The brackets 816 are made, preferably, of composite material, as are the base members 822 and the housing 824. Optionally, the basket 812 ( side walls 812 a, 812 b; ends 812 c, 812 d) is made of composite material. Alternatively one, some, or all of these components are made of steel encased in composite or steel coated with composite. A coating of composite may have the thickness of a layer of paint or of two, three, four or more layers of paint. A shale shaker similar to the shale shaker 810, but with no teaching, motivation, or suggestion of using such composite material for a shale shaker or parts of it, is disclosed in U.S. Pat. No. 6,155,428 incorporated fully herein for all purposes.
FIG. 36 shows a shaker 750 according to the present invention. Material to be treated (e.g. drilling fluid with solids) by the shaker 750 is introduced from a tank 751. Material and fluid flows onto screening apparatuses 752-755 which are mounted in a shaker basket 756. Any of the screening apparatuses 753-755 may be horizontal (see the screening apparatus 753 FIG. 36) or inclined uphill (see the screening apparatuses 752, 754, 755). Vibratory apparatus 757 vibrates the basket 756 and the screen apparatus 752-755. A flowback pan 754 a under the screening apparatus 754 receives fluid flowing through the screening apparatus 754 which flows down to a container 758 and a flowback pan 755 a directs material to the screening apparatus 755.
Material and/or fluid flowing through the screening apparatuses 753-755 flows down into a sump, tank or container 758. The basket 756 is mounted on a frame with springs (not shown). Material not flowing through the screening apparatuses, e.g. separated out solids, flows off the end of the screening apparatus 754 down onto the screening apparatus 755. Material separated out by the screening apparatus 755 flows on top thereof and off the end thereof.
The screen apparatuses 753-755 may be any known screens or screen assemblies used with vibratory separators or shale shakers.
Each screen apparatus 753-755 has an energizable identification apparatus or apparatuses 753 i-755 i, respectively, therein or thereon and/or the shaker 750 has an energizable identification apparatus or apparatuses 750 i therein and/or thereon. Any energizable identification apparatus disclosed herein may be used for the screen apparatuses, vibratory apparatus, and/or for the shaker (including, e.g. RFIDT's and/or SAW's). Optionally, the vibratory apparatus 757 has an energizable identification apparatus 757 i therein or thereon and/or motor weights 757 m have an energizable identification apparatus 757 p.
As is the case with several screens on various shale shakers, the screens 752, 754, and 755 are inclined so that materials thereon must climb “uphill” to exit off the end of the screen. It is within the scope of the present invention to use an energizable identification apparatus (any disclosed herein) with any such inclined screen and with any inclined screen on any vibratory separator or shale shaker.
Optionally the shaker 750 is provided with a reader apparatus 759 (e.g. as any disclosed herein or in the prior art) to read and monitor the energizable identification apparatuses on screens mounted on the shaker 750 and/or on other parts of the shaker 750. Optionally, the reader apparatus communicates with a control system 759 a (on site or remote). The control system 759 a can monitor all the energizable identification apparatuses. With respect to a particular screen assembly, the control system 759 a receives signals, including identification signals, from the screen assembly and it (or any interconnected computer system 759 c, on site or remote) determines whether that particular screen assembly is suitable for use on the shaker 750. If via sensors 750 s the control system determines that the particular screen assembly is not suitable for the material being processed and/or flow rates, the control system and/or computer system can send a signal and/or an alarm and/or can automatically shut the shaker down. Signals from the energizable identification apparatus 757 i can indicate, e.g., motor manufacturing date, last service date, motor refurbishment date, etc. Signals from the energizable identification apparatus 757 p can indicate nominal rated motor force so the control system can ensure correct motor force (operation at correct frequency and operation with correct weight((s))).

The screens 1114 may themselves be sewn, bonded or glued together, e.g. with epoxy, glue, welding, and/or sintering. Rubber strips, plastic strips tape, cushion or cushions 1118 are positioned between the screen 1114 and the upper screen 1116. The strip(s) or cushion(s) 1118 are optional. As shown the strip(s), tape(s), or cushion(s) 1118 are secured to the screen 1114 (or to crests thereof), but it is within the scope of this invention to secure them (or some of them) to the screen 1116. To effect such securement any suitable glue, epoxy, weld, and/or sintering may be employed. The frame 1112 may be any suitable known base, frame or support.
It is within the scope of this invention for the screen 1114 to be any known screen, mesh, screens, meshes, or combination thereof, bonded together, unbonded, or bonded at only certain locations and with any known shape as viewed either from above or on end (as in FIG. 41A). It is within the scope of this invention for the upper screen 1116, which is optional, to be any known screen, mesh, screens, meshes, or combination thereof, bonded together or unbonded, and with any known shape. As shown in FIG. 41B, the screen 1114 is three mesh screens bonded together with coarser mesh on the bottom, medium mesh in the middle, and finer mesh on top. The screen 1116 as shown may be a scalping screen of a mesh coarser than the finest mesh of the screen 1114 or of a multi-layer coarser mesh. In another aspect the screen 1114 is a single screen of closely woven mesh made of any suitable material, e.g. stainless steel and/or plastic material and the screen 1116 is a single screen of coarser mesh made of any suitable material (e.g. but not limited to stainless steel and/or plastic), with the screen 1114 on a metal or plastic frame or support. Alternatively or additionally, instead of the frame 1112 any known perforated plate, strip, support, or series of straps or strips may be used.
In one aspect the strips 1118 are fused plastic strips aligned with peaks of the undulating fine mesh. Such strips may be made of rubber (e.g. nitrile) or plastic, e.g. polypropylene, to inhibit or prevent abrasion of the finer meshes. Such strips can be glued to the bottom of the screen 1116 and/or the screen 1114. Also the screen 1116 can be glued to the screen 1114.
End plugs 1113 and 1115 (FIG. 41D) sealingly close off open ends of the screen 1110. These end plugs may be made of rubber, metal, wood, plastic, Teflon™ material, or urethane. The plugs 1113 extend along two sides of the screen along crests of the screening material to completely seal the sides. The plugs are held in place by friction fit, glue, epoxy, welding and/or sintering. Alternatively, the ends may be covered with screen material.
Fluid flow on the screen 1110 from either end may be from top-to-bottom as viewed in FIG. 41A, bottom-to-top, or from one side to the other.
In one aspect the screen 1116 is a scalping screen of woven steel mesh. In another aspect, it is woven plastic or synthetic or composite mesh; and in another aspect it is a combination of woven steel and woven plastic or synthetic or composite mesh. The screen 1116 may be the same mesh or coarser mesh than that of the screen 1114 or of any layer thereof.
In one embodiment the areas 1117 between the screen 1116 and the screen 1114 are open. The screen 1116 protects the mesh of the screen 1114 from abrasive particles. When the screen 1116 is of a coarser mesh than that of the screen 1114, relatively larger particles retained on the screen 1116 are prevented from damaging and/or hindering flow through the screen 1114.
With the screen 1110 as shown and with the optional screen 1116 liquid flow through the screen is increased by reducing the thickness of the solids bed of the finer mesh screens by the separation of larger particles with the screen 1116.
FIG. 41E shows an alternative embodiment of the screen 1110 with identical parts (indicated by the same numerals) but with additional end plugs 1119 between the upper screen 1116 and the screen 1114. Such “double plugging” may be used on either or both screen ends. A fluid and/or particles introduced to the screen 1110 first encounters the screen 1116 and then material flowing through the screen 1116 flows to the screen 1114. The plugs 1119 may be made of the materials described for the plugs 1113, 1115 and the plugs 1119 may be similarly installed and/or secured in place. Any of the plugs 1113, 1115, 1119 may be deleted in certain embodiments.
As has been described previously, any previously-disclosed energizable identification apparatus may be applied to any part of the screen 1110. An energizable identification apparatus 1120 is embedded within a plug 1115 and/or an energizable identification apparatus 1122 is embedded within a plug 1113. Optionally, an energizable identification apparatus 1124 is embedded within a plug 1119 (FIG. 41E).
Optionally, an energizable identification apparatus 1126 with an antenna 1127 extending therefrom is located within the frame 1112. It is within the scope of the present invention when an energizable identification apparatus being used has an antenna extending therefrom, to adhere the antenna to part of the screen or screen assembly and/or to locate the antenna within part of the screen or screen assembly (e.g. within a frame member, hookstrip, or side mount) and/or to locate such an antenna in a mass of material.
FIGS. 42A and 42B show a screen assembly 950 according to the present invention which has a lower support plate 952 and one, two, three, four or more layers of screening material on the plate 952 (three layers 953, 954, 955 shown). Side hookstrips 956 on sides of the plate 952 facilitate mounting of the screen assembly 950 to a deck or mount structure of a vibratory separator or shaker. An energizable identification apparatus 957 is secured to an exterior portion of a hookstrip 956 and/or an energizable identification apparatus 958 is secured to an interior portion of a hookstrip 956.
