For a intermittent flow injection, use the following data and graphically
decide depth for single point of gas injection.
[10]
Given data :
Depth = 9900 ft. Expected rate = 1070 bbls/day. (100% oil) Tubing size =
2 3 8 inch. Flowing well head pressure = 150 psig, SBHP = 2900 psig.
P.I. = 3.0, Formation GLR = 300, SCF/STB, Sp. Gravity of injection gas
= 0.7, S/C operating pressure = 1000 psig, API = 41, S/C Temp. = 122
F B.H. Temp. = 222 F. 300 psi/1000 ft = flowing gradient of FBHP.
22 psi/1000 ft = casing pressure gradient. Subtract 100 psi from point of
balance. Also calculate the daily gas injection rate necessary if, optimum
GLR = 650 SCF/STB.

Well Depth = 6850 ft.
The static liquid level = 2000 ft. Casing = 5 1 2 inch O.D. Tubing = 2 3 8
inch O.D. T = 164F. During the test on this water well it was seen that,
it is producing 800 bbls/day with liquid level at 3100 ft in the csg., which
then stabilized to above 2300 ft. Use 100 ft safety in setting pump. Tubing
friction is given as 30 ft / 1000 ft. At the surface there is 2100 ft of 2.0
inch flow line with an increase in elevation = 40 ft., with friction = 30 ft/
1000 ft.

b) RCT University has expanded very rapidly introducing a number of
programmes and increasing student intake capacity. It has recently
computerized its examination process based on some off-the-shelf
software. The library had already been computerized a couple of years
back using a freely distributed Library Automation System. Daily cash
transactions are also handled by computers in the Finance and Accounting
Division, using accounting software. For further improvement of
efficiency, the new governing body of the University have entrusted the
task of developing an MIS for the University to a software company.
All these developments were welcomed by a cross-section of the
University Community except a few. One of them is a faculty member at
the Management Science Department who commented that the University
is burdening itself with too many independent information systems. He
strongly favored an integrated information system on the lines of an ERP
for a business organization.
