n: a meter that is proved using a certified prover and then used to calibrate other provers or to prove other meters.

n: a calculation used to inventory the fluids produced from a reservoir and the fluids remaining in a reservoir. Using the equations of the calculation, the volume of original oil in gas in place, the amount of drive-water influx, forecasts of production rates for several years, and estimates of ultimate recovery can be made.

n: (MER) the producing rate of a well that brings about maximum volumetric recovery from a reservoir with a minimum of residual-oil saturation at the time of depletion. It is often used to mean the field production rate that will achieve maximum financial returns from operation of the reservoir. The two rate figures seldom coincide, however.

v: measure the valid length of kelly bar that above the rotary.

n: see pipe prover.

n: a speed-control device on an engine. Mechanical governors consist of flyweights, springs, and mechanical connections to the engines speed control. Compare electrically-actuated governor;hydraulic governor. See governor.

n: the power loss to overcomes the mechanical friction of gears, bearings pistons, packing, or crosshead.

n: schlumberger wireline tool that recovers either 20 or 50 core plug samples in one trip. The cores are cut with a special corebit and driven by an electric motor. Useful to recover high quality core plugs without the demage that explosive core samling caus

n: a weather forecast covering a week or less.

n: the metric unit of service given by a hoisting line in moving 1,000 newtons of load over a distance of 1,000 metres.
