n: The physicist A. E. Boycott found that the blood cell deposits faster when test tube deflects, especially 40°-50°, than when test tube is vertical. The same situation will be found in the drilling fluid in the horizontal well. That is why people call this

n: the theory that minerals such as oil and gas are fully owned in place before they are extracted and reduced to possession. Despite this theory, title to oil and gas may be lost by legitimate drainage and by the rule of capture. Also called ownership in place. See rule of capture.

n: a hypothetical temperature at which there is a total absence of heal Since heat is a result of energy caused by molecular motion, there is no motion of molecules with respect to each other at absolute zero.

zero point on the absolute temperature scale;equal to -273.16 degrees C, or 0 degrees K (Kelvin),or -459.69 degrees F, or 0 degrees R (Rankine).

n: The correspondent curve of actual time from kicking down to completion and depth. Sometimes it includes the moving time.

n: a choke in which the position of a conical needle, sleeve, or plate may be changed with respect to their seat to vary the rate of flow;may be manual or automatic. See choke.

n: A choke in which a conical needle and seat vary the rate of flow.

a pressure step-reduction choke that can be changed while actively flowing the well.

n: a large, sloping sedimentary deposit at the mouth of a canyon, laid down by intermittently flowing water, especially in arid climates, and composed of gravel and sand. The deposit tends to be coarse and unworked, with angular, poorly sorted grains in thin, overlapping sheets. A line of fans may eventually coalesce into an apron that grows broader and higher as the slopes above are eroded away.

land counterpart of a river delta. Characteristic of sediments that have been transported by a fast moving stream then dropped out of the flow as the stream velocity drops as it spreads out. Typical of zones of heavy water runoff such as found at the base

n: a professional multinational organisation of persons employed by governmental units responsible for full-time programs of hygiene and worker health and protection. Address: 1330 Kemper Meadow Drive;Cincinatti, Ohio 45240;(513) 742-2020.

differences in rock – segments showing different responses when measured.

abbr: a trademark name for an annular pressure-responsive valve for a DST string.

annular pressure relief valve. Used in reverse circulating to prevent pipe collapse.
