...") and diametrical (D×L=2"×1") compression using a precision 100kN Instron electromechanical load frame with a constant displacement of 0.05 mm/min. Specimens had distinct lamination and natural fractures. An ARAMIS 3D-DIC image acquisition system was positioned to monitor the samples at a rate of 2 frames per...

... fluids. To measure total tortuosity, a pair of companion plugs, from either Berea SS or the Wolfcamp, were hydrostatically pressurized to 100% saturation, separately with dodecane and 2.5wt% KCl brine (both fluids have NMR Hydrogen Index - HI of 1). Each saturated specimen was then imbibed with its...

.... The fracture properties can be measured in two major experiments: direct shear test and triaxial shear test. Direct shear test is widely used to measure the strength and stiffness properties of rock fractures (Goodman, 1976; ASTM D5607-08, 2008), since it is easy to utilize large scale specimens at both...
