A drilling mud that has 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.

Jun 13, 2018· Drilling Mud Report. Drilling operations rely on the drilling fluids (mud) to do critical tasks like maintain hydrostatic pressure, transport the drill cuttings to the surface, cool the drill bit, and seal/preserve the wellbore. A daily drilling report often looks at the five basic properties of mud monitored or altered during the drilling …
1. n. [Drilling] An average or baseline measure of gas entrained in circulating mud.This baseline trend pertains to gas that is liberated downhole while drilling through a uniform lithologic interval at a constant rate of penetration.The gas is typically obtained from a suction line above the gas trap located immediately upstream of the shale shaker screens, where the gas evolves out of the mud.
The drilling fluid travels up the annular space between the drill pipe and the wellbore, picking up and carrying the drill cuttings up the hole. Once the drilling fluid reaches the surface, it goes through the mud return line to the gas-mud separator and the solids control equipment.
Jul 12, 2021· Drilling mud or drilling fluid is an important component of almost any drilling operation. Mud is mixed in special surface pits and then pumped through the drilling string into the well. After exiting through the nozzles on a drilling bit, mud …
M-I SWACO mud-gas separators are ideal for use where drilling is likely to encounter large volumes of gas. The separators are used primarily to separate and reliably vent large pockets of free gas from the active mud system. Use when drilling and workover are likely to encounter sour gas or to control the well with small, efficient equipment.
The drilling sites of expeditions GMGS1, GMGS3, and GMGS4 in the Shenhu area were located on the top of gas chimneys or mud diapirs, which provided the pathways by which the deep gas-bearing fluids could migrate into the shallow strata and transported the thermogenic gas generated by the Paleogene source rocks and the shallow biogenic gas in ...
