n: formation gas that enters the drilling fluid in the annulus. See gas-cut mud.

gas dispersed in a produced fluid.

n: I. a condition sometimes encountered in a pumping well when dissolved gas, released from solution during the upstroke of the plunger, appears as free gas between the valves. If the gas pressure is sufficient, the standing valve is locked shut, and no fluid enters the tubing. 2. a device fitted to the gauging hatch on a pressure tank that enables manual dipping and sampling without loss of vapour. 3. a condition that can occur when gas-cut mud is circulated by the mud pump. The gas breaks out of the mud, expands, and works against the operation of the piston and valves.

n: the low-pressure area of induction port in pump is filled with departed free gas，which will cause suck inproperly even cutout。

n: a drilling mud that contains entrained formation gas, giving the mud a characteristically fluffy texture. When entrained gas is not released before the fluid returns to the well, the weight or density of the fluid column is reduced. Because a large amount of gas in mud lowers its density, gas-cut mud must be treated to reduce the chance of a kick.

abbr: gas-cut mud;used in drilling reports.

abbr: oil- and gas-cut mud;used in drilling reports.

n: a device in which gascut mud is degassed by the action of a vacuum inside a tank. The gas-cut mud is pulled into the tank, the gas removed, and the gas-free mud discharged back into the mud tank.

n: The equipment using through-going and low pressure of vacuum to degas.
