a fluid, usually dead oil or water, pumped downhole to operate a pump.

n: in subsurface hydraulic pumping, the crude oil that is produced by a well, cleaned, and pumped back into the well to energize the subsurface pump.

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.
