ENHANCING COMPLEX FRACTURE NETWORKS USING NEAR-WELLBORE AND FAR-FIELD DIVERSION

摘要

Methods comprising introducing a treatment fluid into a wellbore and through a perforation into a first propped main fracture at a first treatment interval above a fracture gradient of the subterranean formation, the treatment fluid comprising a first aqueous base fluid, expandable particulates, and degradable particulates; expanding the expandable particulates to fluidically seal the first propped main fracture to fluid flow between the first propped main fracture and the wellbore with the expanded expandable particulates and the degradable particulates; diverting the treatment fluid to a second treatment interval in the subterranean formation along the wellbore, wherein the rate of the treatment fluid creates or enhances a second main fracture therein; introducing a proppant fluid comprising a second aqueous base fluid and proppant particulates into the wellbore at the second treatment interval; and placing the proppant particulates into the second main fracture, thereby forming a second propped main fracture.
