n: a system for automatically measuring and sampling oil or products at points of receipt or delivery. See lease automatic custody transfer.

n: The method assuming that borehole axis of two adjoining measured points is a polygonal line. The length of one part of polygonal line is equal to another part. The deviation angle and azimuth of upper part is same with upper measured point and the deviati

a map containing boundaries, locations and survey points.

an isotope tracer in a bead with the same density of the flowing fluid that is used to track fluid flow rates and therefore fluid entry and exit points along the wellbore.

n: contacts that interrupt the current in the primary circuit of the ignition system in a spark-ignition engine.

n: an eccentrically shaped disk, mounted on a camshaft, that varies in distance from its centre to various points on its circumference. As the camshaft is rotated, a set amount of motion is imparted to a follower riding on the surface of the cam. In the intenal-combustion engine, cams are used to operate the intake and exhaust valves.

a completion technique where casing is cemented in the drilled hole and perforations are placed at the most promising flow points based on log interpretations.

n: the curve assumed by a perfectly flexible line hanging under its own weight between two fixed points. A suspension bridge is an example of a catenary structure;an anchor chain is a catenary.

n: the application of a liquid slurry of cement and water to various points inside or outside the casing. See primary cementing, secondary cementing. squeeze cementing. cementing barge n: a barge containing the cementing pumps and other equipment needed for oilwell cementing in water operations.

v: To prepare and pump cement into place in a wellbore. Cementing operations may be undertaken to seal the annulus after a casing string has been run, to seal a lost circulation zone, to set a plug in an existing well from which to push off with directional

n: The process that different material points attract each other and become major object.
