Reliable forecast of fracture propagation during hydraulic fracturing operations in complex reservoirs rocks is a complicated task. It is tightly coupled to studying their mechanical parameters, microstructure at various scales and elastic strength characteristics of rocks. The goal of this work is to investigate and evaluate the mechanical parameters and boundary conditions of the studied intervals at microscale that need to be created in unconventional rock reservoirs in order to obtain an extensive network of non-main fractures. The scope of the study is in integrating results of microstructural investigations of reservoir rock samples at microscale and dry-state geomechanics. The study addresses the problem of hydraulic fracture optimization by suggesting stress-strain conditions in rocks at which main fractures would have a number of high-branching non-main fractures in order to maximize drainage zone.
