Houston One of the damaging results of mud/elastomer incompatibility is a "chunking" effect. Note that chunks of the stator's elastomer have broken loose, impairing the surface (Fig. 1[17,210 bytes]). This drilling-motor stator has failed because of hysteresis (the conversion of mechanical energy into heat) generated by cyclic pressures in the wellbore. New synthetic drilling fluids contribute to the hysteresis (Fig. 2 [8,942 bytes]). Because of drilling-fluid/elastomer incompatibility, the elastomer in this drilling...
