Oil recovery factor express evaluation during carbonate reservoirs development in natural regimes

Abstract
The article provides a geological and field analysis of the productivity factor and specific balance reserves per well influence on the current and final oil recovery factor during the development of the deposit in natural conditions. The analysis was carried out for various groups of deposits in carbonate reservoirs confined to the lower and middle Carboniferous systems of the Volga-Ural oil and gas province. Empirical dependencies allowing the deposits development monitoring, evaluating the effectiveness of using secondary and tertiary enhanced oil recovery techniques, making sound management decisions to improve the development process not only for the objects of analysis but also for analogue objects have been obtained. Keywords: oil recovery; well grid density; specific balance reserves; oil flow rate; production; oil recovery factor; productivity factor.
