Test II

Question 1

A high-volume well just recently fell below its required economic limit rate due to the continued decline in the natural formation GLR. This well is likely a good candidate for:

Answer 1

gas lift

Question 2

A waterflood is being carried out in a gas-depleted, moderately-deep sandstone reservoir.High WORs are expected. Wells in this field are likely good candidates for

Answer 2

electrical submersible pump

Question 3

A remotely-located gas well makes 10 BFPD. This well is likely a good candidate for

Answer 3

plunger lift

Question 4

Artificial lift becomes necessary when the pwf required to deliver a certain inflow is less than the change in ptbg caused by a fluid with a given flowing gradient. Gas lift provides a solution by artificially

Answer 4

artificially lightening the produced fluid column leading to a reduction in the change of ptbg

Question 5

It is always the best economic decision to produce a well on gas lift at the highest rate possible as determined by optimum gas lift rate calculations

Answer 5

False

Question 6

The best plunger for use in wells with deviations in the tubing inner diameter is a

Answer 6

pad plunger

Question 7

the best plunger for use in wells with paraffin problems is a

Answer 7

solid plunger

Question 8

The part of an electrical submersible pump “pump stage” that adds kinetic energy to the fluid to be produced by accelerating it is called the

Answer 8

impeller

Question 9

An electrical submersible pump is typically set 300-500 ft below the working fluid to

Answer 9

prevent the pump from sucking gas
