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.

Method of treating a well with the formation of proppant structures (variants)

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.

Method of treating subterranean formation

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.
