Abstract

A two-year project entitled "Assessment of the Feasibility of CO 2 Storage in the Russian Permafrost" was carried out in Russia in collaboration with the Siberian branch of the Russian Academy of Sciences. This project delivers new conclusions about the safety role of the permafrost and specific conditions of storage in an area of abnormal geothermal gradient in Western Siberia. One of the specific issues of the project was the potential formation of carbon dioxide hydrates from the injected CO2 and the possible reaction between the existing methane hydrates and the injected CO 2. Maps have been constructed showing the areas of CO2 hydrate stability. A second specific issue was the compatibility of CO 2 storage in the permafrost with oil production. Pilot tests of EOR technologies, involving either the injection of CO2 or the generation of CO2 in situ, proved very efficiency for high-viscosity oil pools. Therefore, we propose to inject CO2 in West Siberia into high-viscosity oil fields. High-viscosity oil fields are mainly located in the centre of the Western Siberian Basin in Khanty-Mansijsk autonomous okrug (KMAO). An alternative or complementary solution is storage in aquifers. Deep aquifers, such as the Pokur formation overlain could also be storage targets, but their potential is unknown because they have not been explored in detail. The inventory of major CO2 sources in Western Siberia has shown that the major CO2 emission in the power sector comes from the KMAO, where power stations in Surgut and Nizhnevartovsk are large CO2 sources. GIS mapping of the permafrost depth and thickness, and the associated stability domain of the CO2 hydrates, has shown that a good overlap could exist between these industrial areas and the stability domain of the gas hydrates, underneath the permafrost. Storage beneath the permafrost as CO2 hydrate is not suitable due to the probable rapid plugging of the porosity by solid gas hydrates. But, the CO2 should be stored at supercritical state in the hydrocarbon fields, with added value of heavy oil upgrading, and trapped underneath a classical cap rock. In addition, the permafrost would act as a secondary cap-rock by trapping the CO2 as hydrates if the primary caprock should fail.
