Gas has greater displacement drive than water, thus making depletion drives more effective.

Determining a well’s back-pressure relationship, as described on pages 28 and 29 of your text, makes it possible to analyze many operating problems and to predict future behavior of a well. (Back-pressure behavior consists of the daily rate of a well’s delivery contrasted with the pressure drop within its reservoir.)

Hydrocarbon pore volume may be expressed in cubic feet, barrels, or acre-feet (the volume of liquid or solid required to cover 1 acre to a depth of 1 foot).

Stage separation allows the recovery of a more stable stock-tank liquid.

A long narrow oilfield would probably be served by a loop gathering system.

All of the following methods of preventing chemical erosion except –

The relationship between the daily rate of delivery of gas at a well and the reservoir pressure decline is usually referred to as the ____________________ behavior of a well.

A convenient standard used with a standard temperature when comparing different quantities (volume) of gas is the _____________________.

If the pores in rock are connected in such a way as to make fluid passage between them possible, the rock is defined as ______________________.

In order for migrating petroleum to accumulate into a commercial amount, it must be stopped by a trap that is –
