The article considers a development system based on controlling the formation stress state. This development system combines the advantages of using horizontal wells with fractures oriented across the horizontal wellbore for fluid production, and horizontal wells with longitudinal fractures for injection of displacement agent. The required orientation is achieved by controlling the direction of fracture growth by controlling the stress state of the formation. The mechanism that allows to control the direction of hydraulic fractures is based on the influence of the pore pressure gradient on the local stress state of the rock mass. However, for the successful implementation of a development system, it is necessary to analyze its stability to a number of geological, geomechanical and technological parameters. A simulator for calculating the direction of initiation and growth of fracture was used as an analysis tool. This simulator is based on a physical and mathematical model of the stressed state of a formation with arbitrarily oriented fractures and a non-uniform pressure field. The model is based on the theory of poroelasticity using the maximum tensile stress criterion to determine the direction of formation and calculate the trajectory of a growing crack. It is shown that the development system is most sensitive to those parameters that are responsible for the energy of the stressed state in the formation. Such parameters include, in particular, the initial stress contrast, as well as the parameters of reservoir thickness and Biot constant. The direction of regional stress does not directly relate to the energy state of the formation, but can affect the energy of the hydraulic fracture system depending on their direction. The permeability of the reservoir determines the time interval in which stress reorientation occurs, the propagation pressure of a hydraulic fracture determines the degree of fracture trajectory deviation of the from the original direction. With the observed deterioration in the reservoir properties of fields, the implementation of this development system with transverse fractures will improve the efficiency of development of hard-to-recover reserves.
