ABSTRACT OF THE DISCLOSURE The present invention relates to an apparatus primarily intended to serve as a pressurized consisto- meter suitable for determining the thickening time of cement slurries under temperature and pressure con- ditions similar to those encountered in the cementing operations involved in oil and gas well completions. A slurry cup, which also serves as the pressure vessel, is held stationary in an externally heated jacket while a DC motor generator is used to rotate a mixing paddle. The motor current drawn by the generator is used as a measure of slurry consistency and the speed of rotation of the mixing paddle is controlled by a gener- ator feedback signal. Modifications to the apparatus enable the apparatus to be used as a pressurized rheo- meter,as an on-line viscometer, as a fluid loss cell, or as an apparatus for conditioning a cement slurry before transferring this slurry under pressure to a standard high temperature, high pressure fluid loss apparatus.
