The paper presents various modified technologies to enhance oil production and to stimulate the inflow of high-viscosity oil, based on a combination of the traditional approach and the use of solvents.
The results of laboratory experiments to study the effects of 29 solvents reagents on high-viscosity oil samples from 5 different objects are presented. Based on the analysis of the obtained laboratory data, basic recommendations are formulated to increase the efficiency of extraction of high-viscosity oil using solvents.
In order to determine the potential for modifying oil recovery enhancement and well stimulation methods by adding solvents to their process, a comparative hydrodynamic modeling of 3 treatment options for the bottom-hole zone and subsequent assessment of their economic effect were carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
