Abstract: This invention relates to the oil and gas industry and can be used to prevent fracture closure by pumping special particulates (proppant) into the fracture after reservoir hydraulic fracturing. According to the invention, the proppant is particulates of sintered ceramic material which are shaped ideal spheres. The use of this type of proppant may increase the well production by 25%.

Abstract: The invention relates to the area of oil and gas production (especially, to the production in which the propping technique is used for the stimulation of a well) and can be used in the development of a composition and a method of production of propping agents (proppant), as well as a method of application of these propping agents. A new type of proppant, proppant production method and use of the proppant are based on allowing the production of proppant having an apparent density of 2.5 to 4.0 g/cm3, as well as a high mechanical strength and a high chemical durability. A proppant contains granules made of the sintered feedstock, wherein the charge mixture containing at least one of the following materials—silicon carbide, boron carbide, titanium carbide, silicon nitride, titanium nitride, boron nitride, silicon oxynitrides, SIALON-type compounds, was used as the feedstock.
