The article notes that Russia currently has more than 20 prospective major oil and gas sites and 36 open fields, including the Rusanovskoye, Shtokman and Leningradskoye gas fields (in the Western Arctic), and those on the Sakhalin shelf and around the Caspian basin. The latter appear to be one of the most promising hydrocarbon production sites discovered in the 21st century. The critique relates that the resource base is of comparable size to the overall hydrocarbon reserves in the North Sea, but more congenial from climactic and physiographic perspectives. These two factors, it notes, have influenced the development of medium- to long-term economic activities primary ones, including fisheries and agriculture, plus secondary oil, condensate and gas-related ones in the Caspian basin. At this stage, the presentation refocuses on data acquired from a systematic toxicological analysis of the environmental conditions in the northern (Russian) sector of that aquatic body. This information shows that the Sea has a reduced level of hydrocarbon pollution and heavy metals, but an inflated one of phenolic compounds. In conclusion, the analysis has rated as satisfactory the existing eco-environmental conditions in the Caspian basins northern sector, with this assessment undertaken during both developmental and production periods of its hydrocarbon fields.
