Abstract

Appts. for degassing and removing sand particles from drilling mud consists of a tank for the mud in which is situated a housing contg. a rotatable hollow body above which is mounted an integral fan impeller. A duct leads from the centre of the hollow body to the fan through which air present in the mud is drawn and thus removed from the system. Heavy sand particles migrate to the walls of the hollow body as it rotates and can be drawn off at the top, while the bulk of the mud leaves via a higher opening. The movement of the mud is caused only by the motion of the hollow sphere and the fan impeller. Appts. is portable and is used for cleaning up during operation the device floats in the mud slurry holding tank.
