Produced gor = total gas (solution + free) production divided by the oil production volume.

Excludes gas lift gas.

Abbreviation: power take off.

A granular substance (sand grains, aluminum pellets, or other material) that is carried in suspension by the fracturing fluid and that serves to keep the cracks open when fracturing fluid is withdrawn after a fracture treatment.

Abbreviation: pounds per square inch per foot.

See propping agent

Proppants, beads, sand used in hydraulic fracturing operations.

Abbreviation: pounds per square inch, gauge.

A string of tubing used to produce the well, providing well control and energy conservation.

A test of the well’s producing potential usually done during the initial completion phase

A paraffinic hydrocarbon that is a gas at ordinary atmospheric conditions but is easily liquefied under pressure.

It is a constituent of liquefied petroleum gas.

Abbreviation: pounds per square inch absolute.

See absolute pressure.

Same as seal nipple assemblies.

An internal-combustion engine or a turbine that is the source of power for driving a machine or machines.

Any packer designed to make a seal between the tubing and the casing during production

An instrument that measures fluid pressure and usually registers the difference between atmospheric pressure and the pressure of the fluid by indicating the effect of such pressures on a measuring element (e.g., a column of liquid, pressure in a bourdon tube, a weighted piston, or a diaphragm).
