Full-scale drilling tests were run to evaluate the effect of mud chemistry on penetration rates in Pierre shale cores. Two polycrystalline-diamond-compact (PDC) bits and nine different muds were used in the tests. In addition to penetration rate, occurrence of bit balling with a given mud type was studied. Results indicate that bit type and mud chemistry affect penetration rates and bit balling significantly.
