n: a decrease in the volume of a stratum due to pressure exerted by overlying strata, evaporation of water, or other causes.

n: The process of breaking cuttings and compacting it into sample with compaction cell when doing preventing caving test.

a crushing of the matrix structure as overburden loads press down on the rock, reducing the pore space. During production of the well, the load on the matrix increases as the pore-filling fluids are removed. These loads may reduce the porosity of the rock

a drive mechanism in a weak zone that displaces fluid by reducing the overall volume of the formation.

n: an oil or gas field comprising wells operated by various operators.

n: I. a mechanism used to transmit power from the engines to the pump, the drawworks, and other machinery on a drilling rig. It is composed of clutches, chains and sprockets, belts and pulleys, and a number of shafts, both driven and driving. 2. a substance formed by the chemical union of two or more elements in definite proportions;the smallest particle of a chemical compound is a molecule. v: to connect two or more power-producing de- vices, such as engines, to run driven equipment, such as the drawworks.

n: the change in volume per unit of volume of a liquid caused by a unit change in pressure at constant temperature. compressibility factor n: the ratio of the actual volume of gas at a given temperature and pressure to the volume of gas when calculated by the idea] gas law.

the volume change of a material when pressure is applied.

n: the act or process of squeezing a given volume of gas into a smaller space.

n: 1. the ratio of the absolute discharge pressure from a compressor to the absolute intake pressure. 2. the ratio of the volume of an engine cylinder before compression to its volume after compression. For example, if a cylinder volume of ]0 cubic inches (10 cubic centimetres) is compressed into] cubic inch (] cubic centimetre),the compression ratio is ]0:].

the ratio of the absolute outlet pressure of a compressor to the absolute inlet pressure.
