Adding gas to an injected fluid or treatment to reduce the injected water volume and provide energy for flowing the well back after the treatment.

n: a well that primarily produces gas. Legal definitions vary among die states.

n: A well that primarily produces natural gas.

n: a device installed in the tubing string of a gas-lift well onto which or into which a gas-lift valve is fitted. There are two common types of mandrel. In the conventional gas-lift mandrel, the gas-lift valve is installed as the tubing is placed in the well. Thus, to replace or repair the valve, the tubing string must be pulled. In the sidepocket mandrel, however, the valve is installed and removed by wireline while the mandrel is still in the well, eliminating the need to pull the tubing to repair or replace the valve.

n: a device installed on a gaslift mandrel, which in turn is put on the tubing string of a gas-lift well. Tubing and casing pressures cause the valve to open and close, thus allowing gas to be injected into the fluid in the tubing to cause the fluid to rise to the surface.

n: a measure of the volume of gas produced with oil, expressed in cubic feet per barrel or cubic metres per tonne. Also called solution gas-oil ratio.

n: a measure of the volume of gas produced with the oil. it is expressed in cubicfeet per barrel.

the number of standard cubic feet of gas contained in a barrel of oil.

n: a well that produces natural gas. gas show n: the gas that appears in drilling fluid returns, indicating the presence of a gas zone.

n: natrul gas well with commercial value .the gas produced by this well
is usually dry gas or the gas contained little condensate oil.

n: in a logging tool, a shutter like device that opens and closes very quickly to permit a measurement of the time a formation is exposed to sound, radioactivity, or other energy;usually timed in millionths of a second (microseconds).

n: a valve that employs a sliding gate to open to open or close the passage in it.

a valve with a sliding bar – common in the oilfield as tree valves.

n: 1. the diameter of a bit or the hole drilled by die bit 2. a device (such as a pressure gauge) used to measure some physical property. v: to measure size, volume, depth, or other measurable property.
