abbr: choke-line friction pressure. clingage n: the amount of oil that adheres to the wall of a measuring or prover tank after draining.

choke line friction pressureClinker: pea to marble sized pellets of raw cement prior to grinding.

n: see shut-in pressure. closed stationary tank prover n: see positivevolume prove1:

n pi: special segmented weights attached to the guy wires of a guyed compliant platform that keep the guy wires taut as the platform jacket moves with the waves and current of the water. As tension on a guy wire is lessened, one or more segments of the weight drop to the seafloor and re-establish tension on the wire. As tension increases on a guy wire, the tension pulls one or more segments off the seafloor so that the wire is not over stressed.

n: a coupling used to connect and disconnect a driving and a driven part of a mechanism, especially a coupling that permits the former part to engage the latter gradually and without shock. In the oilfield, a clutch permits gradual engaging and disengaging of the equipment driven by a prime mover. v: to engage or disengage a clutch.

secondary recovery technique for oil. The carbon dioxide gas is injected and alternated with water. CO2 lowers the viscosity of most oils, but may trigger severe asphaltene and scale precipitates.

n: any material that forms a continuous film over a metal surface to prevent corrosion damage.

a liquid, liquefiable, or mastic composition that, after application to a surface, is converted into a solid protective, decorative or functional adherent film (NACE).

abbr: combination of forward combustion and water flooding. Also called wet combustion.

a tertiary recovery mechanist consisting of combustion and water flooding.

n: The minimal force breaking some stone which suffers overlying formation pressure and whose particles bind with each other.

n: a workover performed with a continuous steel tube, normally 0.75 inch to I inch (1.9 to 2.54 centimetres) outside diameter, which is run into the well in one piece inside the normal tubing. Lengths of the tubing up to 16,000 feet (4,877 metres) are stored on the surface on a reel in a manner similar to that used for wireline. The unit is rigged up over the wellhead. The tubing is injected through a control head that seals off the tubing and makes a pressuretight connection.

n: the leading edge of a cold air mass that replaces warmer air. The warm air is lifted to ride up over the cool air.
