ABSTRACT: Taking into account Biot constant and anisotropy of elastic properties of reservoir rocks, 3D geomechanical modeling was performed, integrated into the process of planning designs and execution of hydraulic fracturing/MSHF operations. The object under the study is represented by a low-temperature carbonate-dolomite reservoir, that complicate the process of developing hydrocarbon reserves by a system of horizontal wells with MSHF was carried out on them. The geological feature of the formation is the presence of clay barrier of insignificant thickness, which cause high risks of hydraulic fracturing breakthrough in the underlying highly permeable gas-saturated intervals. As a result, the construction of a high-quality geomechanical model and its synchronous adaptation together with hydraulic fracturing models become the necessary condition to achieve the planned goals of field development.
