Abstract
An improved gas trap for mud logging is vertically mounted such that its lower end is constantly beneath the surface of mud flowing in a tank. The mud is drawn into the housing where it is agitated to release the entrained gases which are drawn off for measurement. The spent mud is returned to the tank through a mud exit port and related pipe to a point below the level of the mud and remote from the mud intake to the gas trap. This gas trap is insensitive to mud level changes and is relatively free of maintenance requirements.
