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: A method of treating a subterranean formation, including obtaining information of a subterranean formation, generating a three-dimensional model of at least a portion of the subterranean formation, and performing an experiment on the three-dimensional model. The three-dimensional model may be constructed by x-ray scanning of a core of the subterranean formation, and by additive manufacturing using the obtained x-ray image. The subterranean formation may be treated using a treatment designed based upon the experiments performed on the three-dimensional model.

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.

Abstract: A technique includes completing a well, including installing a tubing string that includes a screen in the well and installing a fiber-based material outside of the screen. The technique further includes using the well as an injection well, including communicating a fluid into the tubing string to cause an injection flow to be communicated in a fluid flow path from an interior of the tubing string, through the screen and into a formation.

Abstract: A technique facilitates treatment of a subterranean formation. A proppant and a proppant carrier fluid are delivered to a subterranean location for treatment of the formation. At the subterranean location, heterogeneities of proppant structures are generated with the proppant and the proppant carrier fluid. The heterogeneous proppant structures are then transported into the subterranean formation to improve conductivity.

Abstract: Subterreanean formations penetrated by a wellbore may be stimulated by injecting a well-treatment fluid at a rate and pressure sufficient to create and propagate a fracture in the formation. The treatment fluid comprises a first slurry comprising at least one inorganic cement, water and at least one disruptive agent that may cause the formation of open channels in the fracture through which hydrocarbons in the formation may flow into the wellbore. The disruptive agent may comprise (but would not be limited to) water-soluble polymers that cause flocculation and agglomeration of cement solids, expansive agents, explosive agents, degradable materials, or a combination thereof.
