    摘要: Methods including the steps of selecting a target fracture geometry for a portion of a subterranean formation; selecting a target tip pressure and a target back flow pressure based at least in part on a calculation for the target fracture geometry; selecting a target surface pressure and a target bottom-hole pressure based at least in part on a calculation for the target tip pressure and the target back flow pressure; and introducing a slurry fluid comprising proppant particulates into one or more fractures in the portion of the subterranean formation. The surface pressure corresponds to the target surface pressure, and bottom-hole pressure corresponds to the target bottom-hole pressure.

    摘要: Methods for stimulating a high-permeability subterranean formation are disclosed. In one embodiment, a method comprises the step of selecting a target fracture geometry for a portion of a subterranean formation. The method further comprises the step of introducing a pad fluid comprising a fluid-loss-control additive into the portion of the subterranean formation to create or extend one or more fractures in the portion of the subterranean formation, wherein an amount of the fluid-loss-control additive is determined based at least in part on the target fracture geometry. The method further comprises allowing a barrier to form along at least a portion of the one or more fractures, wherein the barrier comprises the fluid-loss-control additive. The method further comprises introducing a slurry fluid comprising proppant particulates into the one or more fractures, wherein a tip screen-out occurs in at least one of the one or more fractures.
