NSU Scientists Study Carbon Dioxide Storage in Russia

The carbon dioxide storage method (Сarbon Сapture, Utilization and Storage — CCUS) has been used abroad for a long time in Norway, Canada, Germany, the USA, China, etc. to mitigate the effects of climate change. There are currently no active projects in this area in Russia, although there are good prerequisites for its application in the country. Scientists at the ³Ô¹Ï¹ÙÍø and the Trofimuk Institute of Petroleum Geology and Geophysics SB RAS (TIPGG) studied the regions of the Russian Federation from the point of view of the prospects for the storage of carbon dioxide (implementation of CCUS projects) according to regional characteristics. They compiled that shows the zones with the maximum useful «green» effect.

The most promising methods for the disposal of carbon dioxide in world practice are underground gas storage (UGS), depleted hydrocarbon deposits, deep-lying aquifers that are not used for drinking and domestic water supply, as well as artificially created facilities in salt, clay, coal, basalt, and other low-permeability deposits. Since the application of the method is associated with a violation of the natural hydrogeological, hydrodynamic, and geothermal regimes and can lead to atmospheric pollution, scientists studied the prospects in each region. 

Sergey Golovin, Doctor of Physical and Mathematical Sciences, Professor at the , and Director at the «Gazpromneft-NSU» Scientific and Educational Center, talked about this work,

The most generalized forecast level is regional. This makes it possible to assess the territory as favorable or unfavorable for CO2 storage and includes an assessment of the geological structure, structural and tectonic conditions, clarification of lithological, hydrogeological, and geothermal features and environmental restrictions. The next level is zonal. This level makes it possible to map prospective aquifers for the implementation of CCUS projects in plans and geological sections. The third, the local level, of the forecast is conducted taking into account the current license agreements for various types of minerals and the justification of specific objects for the design of landfills for carbon dioxide injection. To date, we have completed the regional forecast, started implementing the zonal level, and created an interactive map describing each region of the country from the point of view of the prospects for storing carbon dioxide. 

As a result of the analysis, Novosibirsk scientists found that within the East European hydrogeological region, the most promising are the Moscow, North Dvina, Vetluzhsky, Volga-Khopersky, Volga-Sursky, and Kama-Vyatka artesian basins. The Pechora artesian basin, located within the Pechora-Barents Sea platform plate, is also highly promising. The promising regions in the West Siberian region are the Tazovsky-Pursky and Irtysh-Obsky, and in the Arctic sector of the East Siberian hydrogeological region it is the Pyasino-Yenisei and Balakhna artesian basins. To the south, the Putoransky, Nizhne-Tungussky, Katangsky, and Priangarsky artesian basins stand out.

Dmitry Novikov, Candidate of Geological and Mineralogical Sciences, Head of the Laboratory of Hydrogeology of Siberian Sedimentary Basins of the TIPGG SB RAS, and Associate Professor at the , described their future plans,

We plan to use the numerical modeling methods of hydrogeochemical processes that accompany CO2 burial and combine their results with geospatial data on hydrogeological structures. This will become the basis for the digital transformation of zonal hydrogeological models and will allow us to offer recommendations on specific burial sites.
