n: a valve, usually only partiallyopen or closed, used to regulate the rate of flow.

n: the volume of fluid that has flowed through a meter during a specific amount of time.

n: the distance from the centerline of the main bearing of a crankshaft to the centerline of the connecting-rod journal. Two times the throw equals the stroke.

a fault’s vertical displacement.

n: a hydraulically operated hammer used in obtaining a seismograph in oil exploration. It is mounted on a vehicle and, when dropped, creates shock waves in the subsurface formations, which are recorded and interpreted to reveal geological information.

n: a collective term for the construction tasks bypassed by regular crews on pipeline construction. Tie-in includes welding road and river crossings, valves, portions of the pipeline left disconnected for hydrostatic testing, and other fabrication assemblies, as well as taping and coating the welds.

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.

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

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.

a fracture treatment, common where high fracture flow conductivity is needed. Very high pressures and very high proppant loadings are applied near the end of a fracture treatment where the tip of the fracture has stopped growing due to bridging of proppan
