Abstract

AbstractIn this study a review is conducted of natural geological formations in European Russia in terms of their suitability for storage of carbon dioxide (CO2) and radioactive waste. The geological conditions of European Russia are described, and the regional features and locations suitable for nuclear waste disposal are identified. A scheme is presented of the location of endogenous activity zones (seismic risks, volcanism) and increased radon risk in European Russia. A map showing suitable areas for nuclear waste storage is presented. The clay formations of the St Petersburg region are reviewed as a potential area for radioactive waste disposal. The main characteristics of the geological conditions that have potential as CO2 storage sites are determined. A conceptual scheme of the CO2 storage potential in north-west Russia, the most favourable region, is presented. Information about geological structures and depleted oilfields in north-west Russia is provided. The near-term outlook for CO2 enhanced oil recovery in the oilfields in north-west Russia and the Kaliningrad region is given. A table of comparative assessments of the geological and economic characteristics of radioactive waste and CO2 storage is also presented in the review.KeywordsRadioactive waste disposalCO2 storageGeological formationsEnhanced oil recoveryRussian Federation
