n: a body of permeable oil-bearing rock surrounded or overlain by an impermeable barrier that prevents oil from escaping. The types of traps are structural, stratigraphic, or a combination of these.

n: A configuration of rocks suitable for containing hydrocarbons and sealed by a relatively impermeable formation through which hydrocarbons will not migrate. Traps are described as structural traps (in deformed strata such as folds and faults) or stratigrap

n: The pressure higher than equalized bottom hole pressure displaying on the riser pipe
or casing.

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: an arrangement of pulleys, or sheaves, through which drilling line is reeved and which moves up and down in the derrick or mast. See block.

the block of sheaves or pulleys that moves with the pipe during running or pulling.

n pi: see snubber defn. 1.

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: The set of sheaves that move up and down in the derrick. The wire rope threaded through them is threaded (or reeved) back to the stationary crown blocks located on the top of the derrick. This pulley system gives great mechanical advantage to the action

n: The block pulley hanging equipment in the jack up system,which include crown block ,travelling block,hook,hanger and wire rope.

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.
