Fig. 4From: Laboratory experiments on the effects of corrosion inhibitor on the mechanical properties of reservoir rockSample strain (axial) versus differential stress (Ļdiff) curves for the Treuchtlinger Marmor limestone samples, obtained at different confining pressures (Pc). Legend is the same for all three panels and shown in panel c. To improve readability, the repeat experiments (performed at 10Ā MPa) are assigned a purple colour instead of yellow. Stressāstrain curves are significantly influenced by fluid type, with different effects depending on the confining pressure. a Limestone with water; b Limestone with inhibitor 1 (3000Ā ppm); c Limestone with inhibitor 2 (3000Ā ppm)Back to article page
