1. Introduction/General Overview of Petroleum
Production
1.1 Definition
In the petroleum industry, production is the
phase of operation that after drilling deals with
well completion, bringing the well fluids to the
surface (pumping), and preparing them for their
trip to the refinery or processing plant (handling
and transportation).
i. Completion
The present production era started in 1808
with a saltwater well that two brothers, David
and Ruffner, had dug in order to extract salt. To
extract more of the concentrated salt water from
the bottom of the well, the brothers decided that
running a pipe or tube (wrapped twine wood)
from the well bottom to the surface would seal
off water in the higher zones and prevent it from
Figure 1: Running a pipe to line the sides o
well and sealing off the outside of the pipe
the bottom prevented Fluids from the form
near the tops from entering the well.
ii. Pumping
In the decade after Drakes discovery well in
1859, a cable-tool drilling rig remained on a well.
The walking beam on the rig that the driller used
to raise and drop the bit could later be adapted
to operate a reciprocating pump. In those days,
steam-driven equipment popularly called
iii. Storage and handling
The industry also had a problem with what to
do with the oil after it came out of the well.
Often wooden barrels were the only containers
available, and early operators used these for
collecting, storing, and shipping petroleum (Fig.
2). A barrel of crude, as it remains till date for
measuring petroleum, equals 42 gallons, or
0.1589 m3 (1m3 is 6.2897 bbls).
Later, earthen pits were used. Handling and
separation were difficult in any scale and became
even more when considerable amounts of water
and sand came mixed with the produced oil.
Tanks slowly replaced wooden barrels, first made
of wood, rivet iron , and finally bolted or welded
steel.
After 1920s, large advances were made in the
operation of lease facilities. Petroleum engineers
improved methods for oil, gas, and water

2.0 Modern Production Methods
In this lecture, the modern methods in
production exercise discusses the advancement
made compared with the techniques and
methods used in designing facilities for well
completion, pumping and handling/storage of oil
and gas in the modern times. It is hereby
