When drilling, the depth of wells is constantly increasing, and as a result, the likelihood of various complications increases. Complications include: loss of drilling fluid; gas-oil-water manifestations, violation of the stability of the well walls, sticking. Almost all complications, if special measures are not taken to prevent and eliminate them, turn into accidents. One of the complications arising from well drilling is hydraulic fracturing. Fracturing pressure is the pressure at which the integrity of the rock in the walls of the well is broken, and artificial fractures are formed. During the drilling process during hydraulic fracturing, the drilling fluid goes into the surrounding rocks. n the proposed scientific work, using the energy condition of destruction, the hydraulic fracturing pressure is determined depending on the mechanical characteristics of the rock and reservoir pressure.
