ABSTRACT A centrifugal drilling mud degasser for use in degas- sing gas-cut drilling mud. The degasser comprises a cas- ing having an inlet port for receiving a gas-cut drilling mud and an outlet port for discharging degassed drilling mud; a rotatable shaft disposed longitudinally within the casing; a plurality of accelerating paddles disposed along the longitudinal axis of the rotatable shaft and attached thereto for moving drilling mud in a rotary motion to create a centrifugal force field and thereby create a vortex within such drilling mud such that drilling mud will move axially towards the outlet port, such that the heavier liquid/solid phase of the mud will be directed toward the inside wall of the casing, and such that gas dispersed within the mud will escape from the mud inwardly towards the shaft to discharge from the casing; and means operably associated with the rotatable shaft for driving the rotatable shaft.
