Analysis of technologies enhancing oil recovery from reservoirs of Azerbaijan’s fields

Wang Jiaojiao - Azerbaijan State University of Oil and Industry

This article focuses on the analysis of modern technologies aimed at enhancing oil recovery from the reservoirs of the Kirmakinskaya Suite on the Absheron Peninsula. The development of these fields is complicated by high heterogeneity, multilayered structure, and variability in geological and production characteristics. The main enhanced oil recovery (EOR) methods are reviewed, including thermal, gas, physicochemical, and microbiological technologies. Among thermal methods, steam-assisted recovery and in-situ combustion have shown successful results in reducing oil viscosity. Gas injection methods, such as carbon dioxide (CO₂) injection, are highlighted for their effectiveness in improving rock wettability and increasing oil mobility.
Special attention is given to ASP – flooding, which utilizes alkali, polymer, and surfactant compositions and has demonstrated high efficiency in increasing the oil recovery factor. The paper presents results of acid treatments and biotechnologies applied in Azerbaijani oil fields, which have significantly boosted oil production. The importance of an integrated approach combining modern modeling techniques, monitoring, and intelligent reservoir management technologies is emphasized.
The study highlights the necessity of considering all physical and geological parameters at the early stages of field development to maximize the recovery of hard-to-extract reserves. The implementation of the discussed technologies enhances the efficiency of mature field development while minimizing environmental impact, which is particularly crucial for the long-term exploitation of Azerbaijan’s oil fields.
