Paper Number: ARMA-2021-1338
... of the poro-mineralogical skeletons at temperatures up to 200 °C. We demonstrate that at high-temperatures, there is a marked increase in all mechanical properties of the porous shale composite due to loss of adsorbed water, primarily from the organo-clay matrix. This has implications for future development...

... fracture network. In this paper, a two-dimensional fracture propagation model is developed. The finite-discrete element method is used to describe the propagation of the fractures. In this model, the rock matrix units are discretized to obtain a discrete fracture network (DFN). The natural fractures...
