Abstract

Introduction. The object of the study is the carbonate deposit of the Lower Triassic Neftekumsk Formation (Zimnyaya-Stavka field and Pushkarskoye field) in the Eastern Stavropol Territory. The purpose of the study is to increase the efficiency of oil field development based on the analysis of field and geological data, deciphering of satellite images and interpretation of structures of central type (SCT).

Materials and methods of research. Regional studies of the fields of the Eastern Ciscaucasia, data on oil deposits and satellite images of various levels of generalization were used. New, non-traditional methods were employed, among which a field-lineament approach and a new method for selecting objects for the additional development of oil fields, based on deciphering of satellite images and interpretation of the structures of central type, taking into account data on the location of zones of increased productivity. Results and discussion.

Research results and their discussion. As a result of the analysis and mapping of wells with the largest accumulated oil recovery from the main productive formations of the studied field, local centers of high-yield zones were identified. A scheme of oil and gas geological zoning of the central type structures and lineament nodes at the studied oil field was built, promising targets for infill drilling and geological and technical operations were identified to increase the degree of development of residual reserves, indicating specific areas for further development of this field.

Conclusion. Based on the analysis of the geotectonic activity of the studied region, the influence of the geodynamic factor on the productivity of wells was established. The use of these approaches will improve the efficiency of forecasting carbonate reservoirs in order to identify promising and developed objects of additional exploration and development for infill drilling, geological and technical operations, and increase the degree of reserves development.
