Figure 4 The differential sticking potential of mixed metal hydroxide (MMH) and KCl/glycol water based muds with and without the ULIF. At low density (9.5ppg), and therefore low solids content, the base mud already has a low sticking potential and the addition of the ULIF has only a small benefit.... More
