a measure of the conductivity of the formation corrected for the viscosity of the flowing fluid. kh/mu.

n: The ratio of the velocity of cuttings to the velocity of drill fluid in the annular in drilling process,which display the throughput capacity of drill fluid.

n: The actual velocity of cuttings in the annular.

n pI: the sum of the fixed costs and variable costs of moving gas or oil.

n: a sucker rod insert pump in which the working barrel travels and the plunger remains stationary. The working barrel is connected to the sucker rod string through a connector and the traveling valve;the standing valve is connected to the top of the plunger, which in turn is connected to the bottom hold-down.

n: one of the two valves in a sucker rod pumping system. It moves with the movement of the sucker rod string. On the upstroke, the ball member of the valve is seated, supporting the fluid load. On the downstroke, the ball is unseated, allowing fluid to enter into the production column. Compare standing valve.

the valve at the top of the pump in a beam pump.

n: a horizontal device in a tower that holds liquid and provides a vapor-liquid contact step. Several common types are bubble-cup, perforated, or valve trays.

n: a vessel wherein gas and liquid, or two miscible liquids, contact on trays, usually countercurrently.

n: a vessel in which oil is treated for the removal of S& W or other objection- able substances by the addition of chemicals, heat, electricity, or all three.

a separator vessel.

n: The ratio of the volume of drill fluid processed by cleanning equipment to circulated volume.
