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 forming a first plurality of fibers in situ 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.

Abstract: This method is designed to facilitate the well treatment with the possibilities for non-uniform/heterogeneous proppant placement in the extended and branched fractures produced by hydraulic fracturing.The essence of the method is to inject a proppant-bearing gel into the wellbore drilled into a productive formation. The low-viscosity fracturing fluid is injected into the wellbore together with the gel fluid (simultaneously or in turns). The method also provides for the injection of gas into the proppant-bearing gel and/or the low-viscosity fluid. The gas can be injected upstream of the junction point, at the junction point, or downstream of the junction point of the flows of the proppant-bearing gel and the low-viscosity fluid. The method further provides for the division of the gel fluid into the separate agglomerates with their subsequent injection into the fractures in the subterranean formation to form the proppant structures in the fracture.

Abstract: The disclosure relates to well systems for producing various fluids, in particular for producing the fluid from the hydrocarbon-bearing formation using hydraulic fracturing. According to the method of hydraulic fracturing of the formation intersected by the wellbore, the wellbore is provided, and the step of injecting the fracturing fluid without proppant to the wellbore is performed to form a fracture in the formation. Then, the step of injecting the fracturing fluid containing a mixture of fine particles and shrinkable polymer fibers is performed and the triggering mechanism is implemented, which causes the shrinkable polymer fibers to shrink, then the flowback of the fracturing fluid is provided and the fracture is cleaned. The provided method allows reducing the impact of the fracturing fluid flow on the proppant pillar geometry, as well as keeping the proppant in a consolidated state inside the agglomerates, pillars, or clogs, and preventing crushing of proppant pillars during the fracture closure.
