Abstract

This paper discusses a medium-scale borehole friction tester with dynamic-filtration capabilities that showed that friction coefficients are affected by mud quality, mudcake, and lubricant addition in low-solids, water-based muds (WBM's). Most measured values, including those from oil-based muds (OBM's), were between 0.2 and 0.3. This paper also reports on new effects of filter cake and solids deposition on borehole friction.
