n: in drilling, the entrance of formation fluids into the wellbore because hydrostatic pressure is less than formation pressure.

influx into the well bore.

n: it is referred to clay swells and flakes off after water influx, one of factors that leads to hole distabilization.

n: an intrusion of formation fluids into the borehole, i.e., a kick.

inflow.

n: a mud whose density is high enough to produce a hydrostatic pressure at the point of influx in a wellbore and shut off flow into the well.

n: a calculation used to inventory the fluids produced from a reservoir and the fluids remaining in a reservoir. Using the equations of the calculation, the volume of original oil in gas in place, the amount of drive-water influx, forecasts of production rates for several years, and estimates of ultimate recovery can be made.

v: 1. for fluid, to fall down a well faster than it can be pumped. 2. to try to pull out of the well faster than the wire line tools are being blown upwards by unexpected pressure. 3. to attempt to pump out a gas influx before the expansion of gas reduces pressure enough to allow the well to kick.

n: in pipeline construction. the hole drilled as the first step of a directionally drilled river crossing. It establishes a pathway for the pipeline.

n: a small-diameter hole that is later opened up to the required diameter. Sometimes used in directional drilling to control wellbore deviation during kick-off.

a small (sometimes) diameter hole drilled through a pay zone to determine the pay top and bottom or various contacts, before the main well position is selected. May also use a pilot hole to better control influx rate.

n: an influx of formation salt water into the wellbore.

n: an operation used to determine temperatures at various depths in the wellbore. It is also used to determine the height of cement behind the casing and to locate the source of water influx into the wellbore.

repeated, regular measurement of temperatures along a unit of depth in a well.
