Fig. 3From: Laboratory experiments on the effects of corrosion inhibitor on the mechanical properties of reservoir rockMohrācoulomb failure envelopes on shear stress (Ļ) versus normal stress (Ļ) plots for Bentheim sandstone. Legend is the same for all three panels. The pink area labelled RMC indicates the uncertainty which was estimated based on the repeat experiments. Slope (friction coefficient Āµā~ā0.8, see Table 2) and intercept (cohesion S0ā~ā19Ā MPa, see Table 2) are unaffected by fluid type. a sandstone with water; b sandstone with inhibitor 1 (3000Ā ppm); c sandstone with inhibitor 2 (3000Ā ppm)Back to article page
