28 Claims

1. A method, comprising:

pumping a first stage consisting essentially of a fracturing pad fluid into a subterranean formation under conditions of sufficient rate and pressure to create at least one fracture in the subterranean formation, the fracturing pad fluid consisting essentially of a carrier fluid and a plurality of bridging particles, the plurality of bridging particles forming a bridge in a fracture tip within a far field region of the formation;

then, pumping a second stage comprising a fluid consisting essentially of a first plurality of fibers into the subterranean formation to form a plug with the plurality of bridging particles directly after pumping the first stage; and

then, pumping a third stage comprising a proppant fluid consisting essentially of a plurality of proppant particles after pumping the second stage.
