GEOLOGICAL-GEOPHYSICAL ANALYSIS OF FEDOROVSKOYE OIL FIELD DEVELOPMENT

Abstract

Background There were 3867 field-geophysical studies carried out in extractive wells and 2364 studies in injection wells, as well as 4413 studies to establish and refine current gas saturation and gas-oil contact at the Fedorovskoye oil field. Studies were carried out in almost all wells that opened the object АС4-8. Over the period from the beginning of field development, the results of 4379 hydrodynamic studies were collected, interpreted and analyzed. Aims and Objectives Profitability analysis of Fedorovskoye oil field development and operation based on geological, hydrodynamic and field data. Results Fedorovskoye oil field development (displacement of oil) through separate productive intervals is extremely uneven. This is indicated by the electrometry data of the condensing wells drilled in the later period of reservoir development and revealed the already planted areas of the oil field. The highest values of the displacement coefficient are attained in high-permeability reservoirs, which lie mainly in the upper and middle parts of the thickness of the reservoir. As a result, the reservoir current state is represented by a layer-by-layer alternation of high-water and medium-watered interlayers. This circumstance considerably complicates the intensification of the remaining oil reserves development in the reservoir being developed.
