n: the injection of air or gas into a liquid. In the oil industry a common form of aeration is the injection of natural gas into reservoir liquids standing in a well. Aeration with natural gas reduces the density of the liquids and allows declining reservoir pressure to lift the liquids. See gas lift.

n: The technique of injecting air or gas in varying amounts into a drilling fluid for the purpose of reducing hydrostatic head. See also Air Cutting.

intoduction of air.

n: see air-cooled exchanger. aerial river crossing n: a river crossing technique in which a pipeline is either suspended by cables over a waterway or attached to the girders of a bridge designed to carry vehicular traffic.

annular flow valve.

n: The process that various drilling fluid samples react totally in the certain condition through a period.

n: The certain temperature in which mud and slurry lay in order to check out the variable relations between time and performance of mud and slurry.

anchor handling vessel.

n: a roller cone bit that is specially designed for air or gas drilling. It is very similar to a regular bit, but features screens over the bearings to protect them from clogging with cuttings and thicker hardfacing on the shirttail to protect them from abrasive, high-velocity air or gas drilling fluid.

n: a part of a LACT unit installed ahead of the metering equipment to separate and remove mass volumes of air and gas from the fluid.
