  • Publication number: 20240067862
    Abstract: Methods include pumping 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 including a carrier fluid and a plurality of bridging particles, the bridging particles forming a bridge in a fracture tip of a far field region of the formation. Methods further include pumping a first plurality of fibers into the subterranean formation to form a low permeability plug with the bridging particles, and pumping a proppant fluid comprising a plurality of proppant particles.
    Type: Application

  • Patent number: 11286760
    Abstract: A system includes a hydraulic fracturing system including a tank having a slurry and an injector line, where the injector line is disposed between a high-pressure pump and a treatment line to fluidly couple to a wellhead. The system includes a plurality of valves disposed adjacent to the injector line and a control system communicatively coupled to the plurality of valves. The control system fluidly isolates the injector line using the plurality of valves, fills the injector line with an amount of the slurry using a first valve of the plurality of valves, and injects the slurry into the treatment line using a second valve of the plurality of valves.
