... fluid pressures spanning 30-55 MPa , and temperatures spanning 30-300° C . We observe a coupled effect of temperature and pore fluid pressure on the shale fault stability. Due to different depositional environments, the mineral compositions of the Longmaxi shales are highly variable. At in-situ...
