... that the formation response to the injection is dominated by the DFN. At a pumping rate of 20 bpm for 15 minutes, sufficient increase in fluid pressure resulted in failure of some area of the DFN both in tension (opening) and shear (slip). The cases with DFN dilatancy indicate lower injection pressure. The case...
