Hydraulic fracturing is one of the most common technologies aimed at increasing the productivity of wells. A detailed analysis of the experience of conducting hydraulic fracturing accumulated for a particular region will help to develop approaches to the successful implementation of the method. In particular, determining size and direction of the fracture is of great interest for the theory and practice of oil production. One of the modern methods to determine the spatial location of a hydraulic fracture and its dimensions is microseismic monitoring. However, not every hydraulic fracturing operation can be accompanied by microseismic monitoring. Thus, in some cases, the application of this control method is hampered by the presence of adverse seismic and geological conditions that impede the passage of waves. It is also necessary to take into account the rise in the cost of the fracturing procedure when it is accompanied by microseismic monitoring. In this regard, it seems relevant to develop a method that allows, according to the integrated processing of geological field material, to solve this problem.
The article presents the results of the data analysis on wells of the Perm region, the hydraulic fracturing of which was accompanied by high-quality microseismic monitoring. For the same wells hydrodynamic research materials under unsteady conditions and production data for 12 months before and after hydraulic fracturing were attracted. A comprehensive analysis of these materials also made it possible to obtain crack parameters with a high degree of convergence with the results of microseismic monitoring. Thus, the article developed an approach to assess the results of hydraulic fracturing based on the use of data from field and hydrodynamic studies, which showed high convergence with the results of microseismic monitoring.
