ABSTRACT:
Water injection wells are fractured by a proppant-laden fracturing fluid to create a propped fracture and wherein the proppant-laden fluid is followed by injection of a substantially proppant-free fluid so that the near wellbore portion of the fracture is free of proppant to minimize pressure drop during water injection and to produce higher injection rates for a given injection pressure. The fracture treatment may include the use of viscous fracturing and displacement fluids which are degraded by the injection of acid-bearing fluids at the end of the fracture treatment cycle. Stimulation or displacement liquid (water) injection may commence immediately after the fracture treatment and may be alternated with miscible gas injection.
