n: a facility consisting of one or more compressors with the necessary auxiliaries for delivering compressed gas.

n: a device in a compressor that closes while gas is being compressed and opens to allow the compressed gas to discharge and uncompressed gas to be drawn in.

n: a quantity of water, drilling fluid, or compressed gas placed inside drill pipe or tubing to control both annular and formation pressures. Usually mud in the pipe or tubing supports prevents the pipe or tubing from collapsing;mud also holds back formation pressure pushing up the pipe or tubing. But sometimes, such as in drill stem testing, it is necessary to have empty pipe or tubing downhole. The cushion protects the pipe or tubing until it is in place. It also allows control of the rising formation pressure as the cushion is removed, as in drill stem testing, to prevent formation damage.

n: The definite water, drill fluid or compressed gas poured into drill pipe or oil tube.

n: the use of the energy that arises from the expansion of compressed gas in a reservoir to move crude oil to a wellbore. Also called depletion drive. See dissolved- gas drive. gas-cap drive. reservoir drive mechanism.

flooding a oil reservoir from the top of the reservoir or an updip location, to push the oil towards a producing well.

n: (OSHA) a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive),or water reactive.

n: explosive and compressed gas (as defined by the Code of Fed- eral Regulations).
