... of sedimentary rock (shale, sandstone, and carbonate) and HDR samples are examined under uniaxial (D 1.5", L 2") and diametrical (D 1.5", L1") compression utilizing a precision 100 kN Instron electro-mechanical load frame with a constant displacement of 0.05 mm/min. HDR samples are collected from the Department...

... model first uses the three-dimensional Displacement Discontinuity Method (DDM) to calculate displacement fields induced by hydraulic fractures. The model then takes into account the occurrence of slippage and calculate the fiber displacement distribution with slippage effect. Additionally, the model can...

.... Firstly, electrostatic forces are the energy that resists displacement of pore water from wet reservoirs during hydrocarbon emplacement. These forces are measured with capillary URTeC 3718137 2 pressure drainage curves. Secondly, the capillary film water and oil phases are immiscible but also bonded...

... Abstract Water imbibition and associated oil displacement is an important process in shale oil reservoirs after hydraulic fracturing and in water-based enhanced oil recovery. Current techniques for water imbibition measurement are mostly "black-box" type of methods. More explicit understanding...

... of equations is used to generate simulated microseismic events for a fracturing treatment. The limited far-field displacement (LFFD) method, is used to generate expected microseismic events. These are then compared with measurements and used to infer the geometry of the created fracture network...
