The optimum composition of the drilling mud was 40 wt% Ririwai biotite as weighting agent. The optimum composition gave mud density and plastic viscosity of 9.0 lb/gal and 3 cp respectively. At the optimum composition, the weighting agent increased the mud density by 2.3% while the plastic viscosity decreased by 50%.
