Tricky growth of crack during the hydraulic fracturing process predetermines technological complications in terms of proppant placement. One of the consequences may be the generation the effect of screenout at the end of the crack. In the process of this generation, the injection can be continued for some time with the accompanying early the proppant fallout and the crack propagation stopping. The practice of artificial application of this process is widespread, when the crack growth is specially stopped. By increasing the crack width, the conductivity increases.
