Apparatus and test methodology for measurement of bit/stabilizer balling phenomenon in the laboratory

Patent

Description

A novel process and apparatus have been contrived for the study of the bit/stabilizer balling phenomenon in the laboratory. The device permits a standard testing procedure using a specially designed bob simulating the drill bit for comparing degrees of balling for different rock formations under different drilling conditions involving variable and controlled parameters like weight-on-bit, revolutions-per-minute (rpm), drilling fluids, etc.
