n: a gas measurement device that consists of a mutiple-ported Pitot tube installed inside a pipe through which gas is flowing;it is installed perpendicular to the flow of gas. The length of the annubar is equal to the diameter of the pipe in which it is installed. An annubar senses the difference between total flowing pressure and static pressure;gas volume is calculated from this difference. See Pitot tube.

a gas flow rate measurement device using Pitot tubes. Common in pipelines.

a formed metal bar (zinc, aluminum, etc.) attached by electrical wire to a structure to be protected and buried in conductive soil near that structure.

the strike plate over a TCP, drop-bar firing system.

n: a cylindrical steel bar (similar to the handle or bail of a bucket, only much larger) that supports the swivel and connects it to the hook. Sometimes, the two cylindrical bars that support the elevators and attach them to the hook are called bails or links. v: to recover bottomhole fluids, samples, or drill cuttings by lowering a cylindrical vessel called a bailer to the bottom of a well, filling it, and retrieving it.

n: A rounded steel bar that supports the swivel and connects it to the hook. May also apply to the steel bars that connect the elevators to the hook (links).

remove solids or fluids from a well.

v: to move or turn (as a flywheel) with a bar used as a lever.

a mass of sand or other materials deposited in the bed of a stream channel.

pressure in atmospheres, approx 14.7 psia.

small diameter hole made in the ground to obtain a sample for the purpose of searching for a gas leak in a pipeline.
