Abstract: A process for hydraulically fracturing a permeable subterranean formation in which the fracture faces are treated to reduce their permeability to the fracturing fluid and propping agent is placed in the fracture in a conventional manner whereby the bulk of the propping agent is deposited in the fracture at a location remote from the well, and thereafter the fracture faces are treated to restore their permeability to subsequently injected fluids and propping agent is again injected into the fracture whereby the bulk of the propping agent is deposited in the fracture adjacent to the well. In this manner, fluid conductively through the fracture is assured.
