a device that, by remote influence, can operate valves or other equipment.

n: The resistivity recorded by electrical logging. It is different from the real resistivity due to the influence of cake, invaded zone and surrounding rock.

resistivity recording where the measured value differs from the true or defined state by the influence of the mud column, invasion of a zone by fluids, or wellbore anomalies.

the area surrounding a well within which drawdown and production has changed the saturation and energy of the system.

n: false influence on well logging measurement caused by the borehole environment, e.g., diameter, shape, rugosity, type of fluid, or mud cake.

n: The distortion of borehole log due to the change of diameter and shape of wellbore or drilling fludi invasion.

n: The process that the performance of drilling fluid deteriorates due to the influence of outer factors.

n: The phenomenon that the clay blocks the formation due to the influence of filter of drilling fluid.

n: the amount of force needed to crush the sides of pipe until it caves in on itself. The pipe collapses when the pressure outside it is greater than the pressure inside it.

n: The required pressure collapsing casing from outside.

external hydrostatic pressure that will cause the onset of pipe yielding. Heavily influenced by tension loads on the pipe.

n: a measure and record of limestone porosity. The log is produced using one source and two detectors instead of just one detector, as an uncompensated neutron log does. A compensated neutron log is less influenced by borehole effects than an uncompensated neutron log. See borehole effect.

natural gas in a normal media, capable of flowing without other influences.

n: the process of breaking down large chemical compounds into smaller compounds under the influence of heat or catalysts. In petroleum refining, the two major types of cracking are thermal cracking and
