Abstract
Abstract The purpose of the article is to enhance the oil recovery coefficient of lower Menilite deposits of the Strutynsky oil field by using an ASP solution (a mixture of three agents: alkaline, surfactant and polymer (ASP)). The tasks were solved by choosing an effective method of enhancing oil recovery by using EORgui software and hydrodynamic modelling software by using Petrel, Eclipse software. Calculations of computer simulations indicate the possibility and technological efficiency of residual oil extraction through the use of ASP solution. After using the method of oil recovery enhancing in the lower Menilite deposits of the Strutynsky oil field by means of ASP solution, the coefficient of final oil recovery will increase from the initial value of 10.4% to the predicted 17.6%. For the first time, geological and hydrodynamic models have been created for the conditions of the Lower Menilite deposits of the Strutynsky oil field, and the most appropriate method for oil recovery enhancing by using the EORgui program has been selected. The suggested method for oil recovery enhancing can be applied within the framework of the concept for reviving the Lower Menilithic deposits of the Strutynsky oil field, as well as in other oil fields of Ukraine, which are developed with waterflood patterns and have similar geological and physical characteristics.
Highlights
Large oil fields with major reserves were discovered in the 60s-80s of the last century and were actively developed and at present time are depleted, full with high water products, and their remaining reserves have moved into the category of hard to recover and depleted [15]
The Strutynsky oil field entered a period of oil production declining and the final stage of its development
The results of the computer simulation testify to the possibility and technological effectiveness of residual oil recovery through the use of alkaline – surfactant – polymer (ASP) solution
Summary
Large oil fields with major reserves were discovered in the 60s-80s of the last century and were actively developed and at present time are depleted, full with high water products, and their remaining reserves have moved into the category of hard to recover and depleted [15]. For effective development of such fields, it is necessary to develop stagnant and undrained zones, to select production zones with smaller thickness in previously allocated areas, and both the undrained under gas cap zones and oil and gas zones to be developed Considering such complicated natural and man-caused conditions because of the small size and uneven production of deposits, the most appropriate way is to use numerical modelling methods and, in particular, the creation of permanent mathematical (computer-based) models for the development process of each individual field, both old and just opened, in order to be used for their development and redevelopment designing.
