3 In the following experiment, the processes of dewatering (for purposes of reducing the volume of a drilling fluid) and flocculating (for purposes of destabilizing the drilling fluid and removing drill cuttings), flocculating agents consisting of polymers and lime were added to a base mud. The resulting reaction caused simulated solids (alum in this case) to flocculate in the mud and with additions of polymeric flocculants caused changes in the mud allowing the solids and liquids to settle out. Concentration ratios of water to mud studied here were 0.5:1, 1:1, 1.5:1, 2:1. The most efficient dewatering and flocculating in the fluids was seen in the lower water to mud ratios of 0.5:1 The results are listed in Table 1 . II. Introduction
