Investigation of dynamic pore pressure in shale gas reservoir during the multi-fracturing and its influence on fault slip

Casing deformation and micro-seismic event in shale gas reservoir has been of growing interest in the industry, which is attributed to the fault slip induced by multi-fracturing in shale gas wells. It has been widely acknowledged that the variation of pore pressure affects fundamentally the fault slip. However, the currently reported analytical models of pore pressure is not available to specially couple the key effects of shale anisotropy and...
