Gazprom Neft and TATNEFT to deploy enhanced oil recovery (EOR) technologies

Gazprom Neft and TATNEFT have concluded an agreement on cooperating in implementing enhanced oil recovery (EOR) projects, under a document signed at the 2021 St Petersburg International Economic Forum by Alexey Vashkevich, Director for Technological Development, Gazprom Neft, and Azat Yagafarov, Deputy Director General, TATNEFT, and Director of TATNEFT’s Moscow Office.

The agreement, which runs to 2030, envisages the establishment of technological test sites at Gazprom Neft’s and TATNEFT’s assets in Western Siberia and the Prizhvolsky Federal District. The partners plan to undertake joint investigations on using surfactants and polymers (polymer and chemical flooding) in EOR operations. Both companies will share experience and skills in devising strategies for developing in-demand oil equipment and services in those locations in which they operate, and are also discussing the possibility of establishing a joint venture to consolidate resources and skills in developing EOR technologies.

Cutting-edge EOR solutions are one of the most important development strategies at mature fields. Gazprom Neft is successfully implementing pilot EOR flooding projects that have seen the oil recovery factor (ORF) at one of its fields in the Khanty-Mansi Autonomous Okrug-Yugra reach 69% — almost twice the average in the Russian oil industry.

TATNEFT has developed and patented more than 200 EOR methodologies, which are being successfully deployed at the company’s facilities and beyond. Engineering processed cover the full production cycle from laboratory investigations to implementation at production facilities — with all knowledge and insights generated from this maintained in a digital library.

“The oil recovery factor in international practice typically varies from 20–50%: in Russia that figure is around 35%. Chemical EOR can significantly increase efficiency in developing even very mature — depleted — fields. These technologies will, literally, give a second life to fields in Western Siberia, and launching the deployment of these is a task of industry-wide proportions.” – Director for Technological Development, Gazprom Neft Alexey Vashkevich.

“EOR methodologies are driving the development of the oil and gas industry: but in developing and launching major innovative projects directed at delivering a significant increase in oil recovery, government support is also required. Combining TATNEFT’s and Gazprom Neft’s experience and skills will make it possible to implement complex projects and solve challenging scientific and industrial tasks, delivering the maximum macroeconomic benefit for the country.” – Deputy Director General, TATNEFT, and Director of TATNEFT’s Moscow Office Azat Yagafarov.
