n: 1. a pressurised device capable of transferring liquid;sometimes used to transfer crude oil and water mixtures if pump agitation would create unwanted emulsions.2. a small tank in which liquids are accumulated and drained by applying gas or air pressure above the liquid level. Such a vessel is usually located below a pipeline or other equipment at a location where an outside power source is not convenient for removing the drained liquids. Sometimes referred to as a drip.

n: the part of the opencircuit diving system that allows a diver to expel all used air directly into the water and avoid rebreathing exhaled carbon dioxide. The regulator reduces the air pressure in the tanks to a divers ambient pressure so that he or she can breathe the air with no resistance. Also called open-circuit regulator.

a type of mixer for cement that uses air pressure to propel the dry cement into the flowing water.

n: a device used to determine the permeability of a core sample by forcing dry air through the sample at the flow rate determined by the pressure differential across the sample. The inlet air pressure and the air flow rate are recorded and, with the dimensions of the sample, are used to calculate permeability.

n: the process of remedying or restoring an area or situation to its natu- ral (or as close to natural as possible) state. remote BOP control panel n: a device placed on the rig floor that can be operated by the driller to direct air pressure to actuating cylinders that turn the control valves on the main BOP control unit, located a safe distance from the rig.

n: a method of artificial lift in which a subsurface pump located at or near the bottom of the well and connected to a string of sucker rods is used to lift the well fluid to the surface. The weight of the rod string and fluid is counterbalanced by weights attached to a reciprocating beam or to the crank member of a beam pumping unit or by air pressure in a cylinder attached to the beam.
