ANALYSIS OF NEGATIVE CONSEQUENCES DURING A HYDRAULIC FRACTURING

Background Currently, the share of hard-to-recover natural oil reserves in the development of oil and gas-oil fields is increasing, and the volume of work to increase the oil recovery ratio is increasing. Hydraulic fracturing is one of the effective methods of production enhancement and enhanced oil recovery. Aims and Objectives To determine the qualitative geological and physical information about the structure of the development object when designing the processes of geological and technical measures. To prove the negative consequences arising after the work on intensification and increase of oil recovery factor. To establish the effect of water-cut wells on the effectiveness of hydraulic fracturing. Results The main aspects of the correct construction of the geological and hydrodynamic model are selected. The possible negative consequences arising due to improper design of the hydraulic fracturing process are analyzed, and ways to prevent them are justified. The influence of the aquifer interlayers was noted during hydraulic fracturing in production wells with a high level of irrigation.
