... stimulation with monotonic injection. Our test results show that the pre-breakdown cyclic injection fracturing reduces the FBP by as much as 60% compared to the monotonic injection pressure and enhances the fracture permeability by a factor of 2-to-6 even at 5000 psi confining pressure. SEM statistical...

An increase in injectivity implies an increase in fluid volume that can be injected per time at a given injection pressure. Our results suggest that the injectivity of hydraulically...
