Abstract:
A method of fracturing a tight subterranean formation comprising: introducing a cement composition comprising cement and water into the tight subterranean formation thereby creating or enhancing a fracture in the tight subterranean formation, wherein the tight subterranean formation comprises at least one formation zone with a permeability of less than 1 millidarcy; allowing the cement composition to set within the fracture; and creating a permeable flow path within the set cement composition using pressure pulses. Another method comprises introducing a treatment fluid into the tight subterranean formation at or above the fracture gradient of the set cement composition to create or enhance a permeable flow path within the set cement composition.
