Abstract
Unconventional reservoirs, in terms of their totality of properties, are unique geological objects for which there are no generally accepted and widely tested effective methods for studying cores, interpreting well logging and seismic forecasting. For the effective development of this type of reservoir, as a rule, horizontal wells with multistage hydraulic fracturing are used, providing the maximum possible stimulated volume of rocks (SRV) and an increase in the initial and accumulated production rates. The result of hydraulic fracturing largely depends on the brittleness of the rocks and the presence of zones of natural fracturing. Prediction of these properties in the interwell spacing is a complex task that requires modern seismic processing and interpretation approaches
