Abstract
The study considers the issue of depleting reserves of a development object is at the final stage of development and is characterized by a decrease in the efficiency of the oil extraction process due to the gradual deterioration of the structure of residual mobile oil reserves. Based on the detailing of the geological structure of the object, which has a clinoform structure and includes three terrigenous layers, analysis of field studies and geological and hydrodynamic modeling, it was established that the areas of localization of reserves are confined to the bottom parts, which are characterized by deterioration of filtration parameters and increased dissection. Based on the results of the analysis, a strategy for extracting reserves was developed, which included hydraulic fracturing in high-thickness zones of the dissected part of the reservoir, the further implementation of which showed high success.
Materials and methods
Data on the geological structure, including the sedimentation model, intrastratal correlation and distribution of filtration and reservoir properties over the area and section. Indicators of operation of production and injection wells, results of field geophysical studies, results of inflow stimulation methods.
