Drilling mud degasification apparatus comprises a degassing chamber located below the level of gas-laden mud in a tank. A propeller pump causes the mud in the tank to flow through a plurality of restricted orifices in the degassing chamber at a rate faster than that at which the mud would normally flow through such orifices to liberate the gas bubbles therefrom. A cyclone separator finally separates the so-liberated gas from the mud.
