The Spiral Flow Cylindrical Mud Mixer (SPCMM)* is a unique system recently developed for mixing large volumes of mud quickly under controlled conditions. Its streamlined internal shape allows regular flow by minimizing obstructions. A well organized flow pattern from the outside walls of the mixer into the centrally located suction eliminates dead spots and promotes uniform mixing of the contents. Field tests indicate that this system will mix mud approxiamtely four times as fast as other existing systems. The speed of mixing up to this time has been determined by the limitations of adding materials to the mixer, and not the speed of the mixing action of the mixer.

This new system may be applied whenever an operator needs large volumes of mud with carefully controlled properties to solve well control problems. Plant tests have shown that this mixer will produce 214 bbl. of 17+ lb/gal. mud in a 24 hour period.

The SFCMM* is a unique mixer that provides more uniform mud at higher rates than that provided by other mixers available.
