Scientists from the Siberian Federal University (SibFU), which is part of the Yenisei Siberia Research Center, have developed a composition of nanosuspensions to increase oil recovery. Studying the oil recovery processes, experts came to the conclusion that the various additives depend on what the oil recovery coefficient will be, and how much it will increase in comparison with standard oil production methods.
The extraction process using a suspension is as follows: nanoparticles of various shapes are added to a liquid that replaces oil in the reservoir. Penetrating into the porous structure of the reservoir, it pushes oil, which cannot be obtained by other means, to the surface.
“This makes it easier for oil to separate from the rock, and the reservoir’s output increases significantly. This is especially important for hard–to-recover oil reserves, the number of which is very significant in the Russian North,” said Vladimir Zhigarev, co-author of the study and researcher at the Laboratory of Physico-chemical Technologies for the Development of hard-to-recover hydrocarbon reserves at SibFU.
SibFU scientists are currently experimenting with formulations and testing a range of nanosuspensions with the addition of spherical particles of silicon oxide and aluminum oxide, as well as aluminum oxide nanofibers.
The research was carried out with the financial support of the Ministry of Science and Higher Education of the Russian Federation.
For reference:
The world-class scientific and educational center “Yenisei Siberia” was established in 2019. It is an interregional association initiated by the Krasnoyarsk Territory, the Republics of Khakassia and Tuva. The participants of the REC include 28 scientific and educational organizations and enterprises of the real sector of the economy. During its operation, the Yenisei Siberia Scientific and Educational Center has formed more than 50 comprehensive projects for the development of new technologies, bringing together leading scientific, educational and industrial organizations of the region and the country.
