a surface piston driven pumping unit, similar to a beam lift unit.

n: a beam pumping unit on which the counterbalancing is done by means of an air cylinder.

n: any method used to raise oil to the surface through a well after reservoir pressure has declined to the point at which the well no longer produces by means of natural energy. Sucker rod pumps, gas lift, hydraulic pumps, and submersible electric pumps are the most common means of artificial lift.

one of several methods that provide pressure assistance to increase flow from a well. The most common systems lighten (decrease density) of the flowing fluid (gas lift),or remove all or part of the liquid head from the reservoir (beam and electric submer

n: (1) the extreme width (breadth) of the hull of a ship or mobile offshore drilling rig. (2) a walking beam. See walking beam.

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.

an artificial lift system, common to low pressure, lower rate oil wells, with a plunger type bottom hole pump operated from the surface by a rod string.

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.

n: a well whose fluid is being lifted by rods and pump actuated by a beam pumping unit.

n: a beam pumping unit that has a counterbalance weight on the walking beam.
