25 Claims

1. A method, comprising:

pumping a fracturing pad fluid into a wellbore traversing a subterranean formation under conditions of sufficient rate and pressure to create at least one fracture in the subterranean formation, the fracturing pad fluid comprising a carrier fluid, a plurality of bridging particles, and one or more polymers coating the plurality of bridging particles, wherein the bridging particles form a bridge at a fracture tip within a far field region of the subterranean formation;

pumping a treatment fluid into the subterranean formation to mix with the fracturing pad fluid;

adjusting at least one parameter of the treatment fluid being mixed with the fracturing pad fluid, and thereby causing the one or more polymers to form a first plurality of fibers in situ, wherein the first plurality of fibers forms a plug with the bridging particles; and

pumping a proppant fluid comprising a plurality of proppant particles.
