Approaches to the effective implementation of SWAG-technology and technology for intrastratal carbon dioxide generating

Abstract

This article provides an overview of the results of studies of water-gas methods and carbon dioxide generation in reservoir conditions as methods for increasing oil recovery. It is shown that the efficiency of technology implementation is influenced by the choice of technical device and the composition of the selected agents selected for injection into the reservoir. The effectiveness of the implementation of these methods is directly influenced by reservoir conditions (pressure and temperature), as well as the mineralization composition of the liquid phase (injected in the form of a water-gas mixture or formation water). It turned out that in the case of an optimal mineralization composition of the liquid, the technological efficiency of the methods increases. In other cases, it is necessary the composition and concentration of surfactants are given. Recommendations on the composition and concentration of surfactants are given. To implement methods in a specific field, it is recommended to conduct laboratory studies to determine the optimal composition of the agent acting on hydrocarbon-saturated rock.
