n: the prevent sticking joint that connected the top of fishing tool.

v: To stop drilling or production operations when it becomes unprofitable. A wildcat may be abandoned after poor results from a well test. Cement plugs are placed in the wellbore to prevent fluid migration between different zones.

v: I. to take in and make part of an existing whole. 2. to recover liquid hydrocarbons from natural or refinery gas in a gas- absorption plant. The wet gas enters the absorber at the bottom and rises to die top, encountering a stream of absorption oil (a light oil) travelling downward over bubblecap trays, valve trays, or sieve trays. The light oil removes, or absorbs, the heavier liquid hydrocarbons from the wet gas. See bubble-cap tray, sieve tray, valve tray.

to fill part or all of the pore spaces.

a precision sized micron particle material used for testing the solids stopping capability of filters.

n: English system buttress thread whose top angle is 29°. Mainly used to convey dynamic.

n: a reaction in which an element has been changed into an unstable isotope during bombardment by neutrons.

near formation area is irradiated with neutrons that transform some nuclei into isotopes. The isotopes produced can be detected by radioactive energy levels and decay time. The original elements can be described from this behavior.

n: in tank sampling, a sample that is obtained by submerging a stoppered beaker or bottle to a poinias near as possible to the draw-off level, then opening the sampler and raising it at a rate that makes it about three-quarters full (maxi- mum 85%) as it emerges from the liquid.

a patented screen design that allows gravel packing slurry to flow past an annular bridge point that would normally stop the placement of gravel.

n: a hydrocarbon trap in which petroleum accumulates in the top of an anticline. See anticline.
