n: a part of a LACT unit installed ahead of the metering equipment to separate and remove mass volumes of air and gas from the fluid.

n: a body of air that remains for an extended period of time over a large land or sea area with uniform heating and cooling properties. The air mass will acquire characteristics (such as temperature and moisture content) of the underlying region.

n: an area over which an air mass rests and develops temperature and moisture characteristics typical of that location.

radioactive decay process where the loss of an alpha particle from the nucleus lowers the atomic number by two and the atomic mass by four.

the ratio of the mass loss of actual corrosion of an anode to the theoretical corrosion mass loss calculated from the quantity of electricity that has passed between the anode and the cathode using Faraday’s law (from NACE).

chemicals which prevent hydrate crystals from sticking together and forming a larger mass.

v: 1. to collect a mass of sticky consolidated material, usually drill cuttings, on drill pipe, drill collars, bits, and so forth. A bit with such material attached to it is called a balled-up bit. Balling up is frequently the result of inadequate pump pressure or insufficient drilling fluid. 2. in reference to an anchor, to fail to hold on a soft bottom, pulling out, instead, with a large ball of mud attached.

n: The phenomenon that drill bit or drill tool is surrounded by cutting and viscous mud in drilling progress.

a mass of sand or other materials deposited in the bed of a stream channel.

n: reservoir rock formed from a mass of sand, gravel, or alluvium deposited on the bed of a stream, sea, or lake by waves and currents.
