Abstract
Large fields in Western Siberia are at the latest stage of development, which are characterized by low rates of oil production, high water cut of the extracted resources and a decrease in the number of operating well stock. Current circumstances make it necessary to recover undeveloped volumes of remaining oil in place by using hydraulic fracturing on a complicated stock of candidate wells (risky water cut zones, marginal areas of the deposit, poorly continuous shale barrier). All this leads to an increase in the probability of premature flooding of wells due to hydraulic fracture breakthrough in non-target water-saturated formation, and as a result, obtaining a low effect of oil-production rate because of all available reserves are not involved in the filtration process to the well. For optimal planning of hydraulic fracturing design requires reliable information about the geomechanical parameters of the rock, its structure and azimuth direction, which plays a key role. The purpose of the work is to determine the dominant direction of the maximum horizontal principal stresses in the deposits of Western Siberia by the integrated use of well logging and microseismic monitoring for each of the groups of objects (A, B, Achim and J), as well as to provide practical examples of the application of technological methods to hydraulic fracturing that can reduce the level of water cut during the wells exploitation time.
