... and interpreting the toughness from the breakdown pressure (Abou-Sayed et al. 1978). However, the interpretation of the observed breakdown pressure relies critically on assuming that (i) the fluid pressure in the slots and the cracks ahead is uniform and (ii) the peak (breakdown) pressure is the fracture...

... 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...

... ABSTRACT: We conducted laboratory experiments that demonstrate how an increase in fluid pressure can induce “stick-slip” events along a preexisting fault. Our sample is a 760 x 356 x 76 mm poly(methyl methacrylate) (PMMA) plate with a saw cut simulated fault deformed in a biaxial loading...

Through our investigations, we find that the competition between the fluid pressurization and mechanical stress transfer associated both to pressurization and co-seismic rupture is a viable mechanism for seismic events...
