n: The knockout drum that removes the gas invading into the drilling fluid inatmosphere pressure.

n: 1. water produced with oil. It usually settles out within five minutes when the well fluids become stationary in a settling space within a vessel. Compare emulsified water. 2. the measured volume of water that is present in a container and that is not in suspension in the contained liquid at observed temperature.

1. the excess water that separates from a cement slurry on standing. 2. the first water that separates from the crude oil in the first stage of the separator (free water knockout or FWKO).

the first stage of separation in a crude that contains a large amount of water.

n: (FWKO) a vertical or horizontal vessel into which oil or emulsion is run to allow any water not emulsified with the oil (free water) to drop out.

abbr: free-water knockout.

see Free Water Knockout.

n: a component in the contactor of a glycol dehydration unit that recovers any glycol that has gotten past the mist extractor.

n: a vessel that heats an emulsion and removes water and gas from the oil to raise it to a quality acceptable for a pipe- line or other means of transport. A heater- treater is a combination of a heater, free- water knockout, and oil and gas separator.

n: any liquid condensed from a stream by a scrubber following compression and cooling.

a separator used to remove easily removed or excess gas or water from the produced fluid stream.

n pi: (slang) chemical used to treat an oilfield emulsion when it is being tested to determine the amount of treating chemical required to break the emulsion.

n: a plugging device used to effect a dry tubing during run in. It is opened by knocking it out of the tubing;used with retainer and packers.
