n: the weights on a beam pumping unit installed on the end of the walking beam, which is opposite the end over the well. The counterbalance offsets, or balances, the weight of sucker rods and other downhole equipment installed in the well.

n: a machine designed specifically for sucker rod pumping. An engine or motor (prime mover) is mounted on the unit to power a rotating crank. The crank moves a horizontal member (walking beam) up and down to produce reciprocating motion. This reciprocating motion operates the pump. Compare pump jack.

Behind-pipe reserves are expected to be recovered from zones in existing wells, which will require additional completion work or future recompletion prior to the start of production.

n: a protective grill or cover for a belt and pulleys.

the equation is used in the design of chokes and explains the manner in which pressure in the body in the body of the choke, downstream of the first pressure drop, is lower than the eventual recovery pressure at the end of the choke.

the returning wave of gravel after the alpha wave when packing a well over about 55o deviation.

n: the first cross-country pipeline with a 24-inch (61-centimetre) diameter. The 1,340-mile (2,157 -kilometre) Big Inch was begun in 1942 with government financing as a part of an emergency construction program (War Emergency Pipelines) to meet the demand for petroleum products during World War II.
