Annotation:
Despite the long history of oil fields development, today carbonate reservoirs remain poorly studied compared to terrigenous ones. The main reasons for this are the imperfection of the existing methods applied for conducting hydrodynamic studies, core material studies and the lack of correlation of direct interaction in the inter-well space along fractured reservoirs due to their anisotropy. The article studied the azimuthal anisotropy in the crack propagation intervals during hydraulic fracturing and the data obtained by acoustic method and ground micro-seismic monitoring method are compared to determine the directions of natural fracturing of carbonate reservoirs of the Vereiskian-Bashkirian deposits of the Dachnoye deposit in the Republic of Tatarstan. The results obtained by the authors can be further applied when designing and developing oil deposits in this region.
