... 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...

... (TMS) formations. The samples are obtained in the way that the imbibition rate in the direction parallel and perpendicular to the bedding can be investigated. One-end-open boundary condition, where the specimen is in contact with the rock from one open side only, is selected to better understand...

... to the specimen and then the deformation of the specimen during imbibition is captured using a digital camera. The images are analyzed using a 2D-DIC image processing software to obtain displacements and strains. Tuscaloosa Marine Shale samples with 35% to 52% clay are tested in interaction with water.

In this study, we measure permeability of shale specimens shear fractured at stressed conditions and combine these measurements with concurrent x-ray tomographic characterization of the fracture systems. The fractures were created using a specialized triaxial system configured for either direct...

.... 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...
