en.Wedoany.com Reported - Tatneft is advancing carbon dioxide capture and utilization technologies, including a process that enhances oil well productivity through cyclic gas injection. Azat Zaripov, First Deputy Director of Tatneft's Research and Design Institute (TatNIPIneft), explained that in this technology, CO₂ is used as a solvent to improve crude oil mobility.

The company plans to source carbon dioxide for injection into oil wells from the Taneco refinery in Nizhnekamsk. A CO₂ capture unit with a design capacity of 100 tons per day is currently under construction at this refinery.

Following technology validation, Tatneft intends to scale up operations. The company will capture over 9.8 million tons of carbon dioxide from flue gas emissions at the Nizhnekamsk thermal power plant and Taneco, using area flooding to enhance oil recovery more effectively.

The group is also researching projects for CO₂ storage in aquifers and plans to introduce biotechnology in the future, utilizing bacteria to produce methane, methanol, formate, and other products from CO₂.

Tatneft has conducted all necessary scientific research and experiments for creating underground carbon storage reservoirs and has obtained permits for injection into aquifers. A representative from TatNIPIneft stated that a pilot industrial injection aimed at bioconversion is planned for 2027.
