... experiments have been conducted on four shale samples using methane and nitrogen as flowing fluid. At each stage, mean pressure and mean effective stress is held constant and permeability is measured at various gas flow rates. Mean pressure is then raised and the tests are repeated at the next stage...

... computing, is used to simulate the permeability tensor inside the fracture. Significant proppant embedment is observed in the sandstone rock when the effective stress is increased to 4,200 psi. Consequently, fracture porosity is reduced by nearly 70%, and permeability is reduced by two orders of magnitude...

... ) or displacement discontinuity methods ( Tao et al., 2009 ). The approach considered in this study assumes that the nature of the creation/enhancement of fracture system can be represented by pseudo-continuum with dynamically changing permeability (as a tensor) as a function of effective stress. The matrix...

.... Different phenomena affecting the magnitude of fracture width are easily examined, such as the presence or absence of leak-off, isothermal or non-isothermal fracturing as well as initial effective stress in the formation. Results show that the fracture width continuously decays with time due to the effect...
