irregular or reducing pipe.

n: a well that produces from a reservoir of low permeability and thus stabilizes slowly. Such wells show slow buildup of bottomhole pressure on a buildup test, and the flowing pressure does not stabilize quickly at a constant value on a flow test.

v: to add oil to a system, which causes the oil to break out and rise to the surface.

trip in hole.

n: The swivel that there have a tiltable hydraulic cylinder in it ,which can slope along the axis.

n: an automatic sample usually obtained from a pipeline and taken at regular timed intervals.

n: feature built into oilfield inhibitors that allows them to be introduced into production systems and their active ingredients to be released at timed intervals.

n: a layer of rock, with or without facies variations, deposited during a distinct geologic time interval. Compare rock stratigraphic unit.

n: the relationship of all moving parts in an engine. Each part depends on another, so all parts must operate in the right relation with each other as the engine turns.

n: a set of gears in an engine, driven by the crankshaft, set to drive the equipment necessary for the engines operation. Engine equipment driven by the timing gears includes the oil pump, intake and exhaust valve mechanisms, fuel injectors, and magnetos.
