Tatneft Prepares for CO2 Injection into the Reservoir
Tatneft has received a subsurface license for the Tukaevsky-1 site in Tatarstan for the construction and operation of underground facilities where the company plans to store carbon dioxide (CO2).
The site covers the territories of the Nizhnekamsky, Tukaevsky, and Zainsky districts, according to Interfax. According to the State Register of Subsurface Sites and Licenses, the right of use is granted until May 28, 2030.
Based on a decision by Rosnedra, part of the Tukaevsky site was excluded. This was done within the framework of the license for geological exploration and evaluation of the site’s suitability for the construction and operation of underground facilities.
In August 2024, it was announced that the State Reserves Committee (GKZ) recognized Tatneft’s site near the Nizhnekamsk industrial zone as suitable for CO2 storage.
“Usually, within a year after the results of the examination, a project is prepared,” explained Nina Yerofeeva, Head of the Department of Oil and Gas Geology, Groundwater and Facilities at Rosnedra. “And then comes the construction.”
Tatneft has repeatedly announced plans to capture carbon dioxide from exhaust gases at the Nizhnekamsk CHPP-2and at the Taneco refinery. CO2 injection into the subsurface is intended to enhance oil recovery from reservoirs.
Tatneft has developed a technological scheme for injecting liquefied CO2 into geological structures. Specialists have also selected equipment for pipelines, designed wells, and developed surface infrastructure.
At present, at least ten similar licenses have been issued to Russian subsurface users. In recent years, Gazprom Neft, Novatek, Rosneft, Lukoil, EuroChem, Rosatom, and other companies have announced similar site studies.
