Russia's Recent Past and Future in Oil & Gas Production Dr. Iskander Diyashev Chief Engineer, Sibneft Member of Russian Academy of Natural Sciences e-mail: [email protected] Summary • Russia is capable of increasing its oil production to 12 mln bbls per day over the next 7 to 10 years. • This will require about 12 bln $ per year in oilfield CAPEX. • The Russian resource base is much larger than it is commonly believed, at least over 150 bln bbls of oil (not just BOE) Recent past and the future • Oil production in Russia has grown from 6 to almost 9.4 mmbopd the last 7 years. Exports: 3.7 mmbopd (1H 2005). • My estimate is that Russian oil production will peak at about 12-12.5 mmbopd (historical maximum of the USSR) during the decade of 2010 to 2020. Available for export 6.7 mmbopd. MajorMajor producingproducing areasareas andand ExplorationExploration maturitymaturity From Dr. Raymond C. Leonard presentation Future of Russian Oil • During 2010-2020 the decline of Western Siberian production will be compensated by the development of the new oil fields in Eastern Siberia (available for export 1.1 mmbopd in the Pacific), Timan-Pechora and Russian Arctic offshore (available for export 1.0 mmbopd in the Atlantic). • After 2020 the decline of Western Siberia will not be compensated completely, and it will result in a gentle annual decline of approximately 5%.

In the present study, the genetic structure of Atlantic walruses (Odobenus rosmarus rosmarus) occupying the Pechora Sea (PEC) in the western Russian Arctic, including walruses from Svalbard–Franz Josef Land (SVA–FJL) and East Greenland (EGR) regions, was investigated using 14 microsatellites (N = 159) and mtDNA sequences (N = 212). Bayesian-based clustering analysis identified two clusters: EGR and the other Northeast Atlantic areas. Pairwise FST analyses based on microsatellites revealed low but significant genetic differences between walruses from the PEC and SVA–FJL groups, which was supported by mtDNA analysis. FST was not significant for all sampling years, indicating a temporal effect or male-biased gene flow. Extended Bayesian Skyline Plots suggested a constant female subpopulation size (Nef) for EGR and an increase for the SVA–FJL and PEC groups that commenced around 40–30 Kyr ago, indicating different demographic histories for walruses in the EGR.

Modern basins in this region contain relics of palaeo-basins of a certain tectonotype formed in varying geodynamic regimes. Petroleum potential estimates of the Western Arctic vary broadly—from 34.7 to more than 100 billion tons of oil equivalent with the share of liquid hydrocarbons from 5.3 to 13.4 billion tons of oil equivalent. At each stage of the development of palaeo-basins, favourable geological, geochemical and thermobaric conditions have emerged and determined the processes of oil and gas formation, Citation: Egorov, A.S.; Prischepa, migration, accumulation, and subsequent redistribution between different complexes.

Experience from development of this field, where there are still many uncertainties, will have large consequences for the further development program and relations with foreign companies. The exploration activity going on is fairly limited, but over the last few years there has been a struggle over licenses and control over exploration capacity. In the medium term the goal of rapid development of the Arctic continental shelf has become intertwined with a comprehensive government effort to modernise the domestic shipbuilding industry to make it able to cover most of the needs offshore. With the shipbuilding industry in a deep crisis these goals are not fully reconcilable. Russia will either have to accept more foreign involvement, or scale down its offshore ambitions. We believe a combination of the two alternatives is likely.

  • North-West Russia As a Gateway in Russian Energy Geopolitics
    North-West Russia as a gateway in Russian energy geopolitics MARKKU TYKKYLÄINEN Tykkyläinen, Markku (2003). North-West Russia as a gateway in Russian ener- gy geopolitics. Fennia 181: 2, pp. 145–177. Helsinki. ISSN 0015-0010. This paper examines Russian energy development and plans and their geopo- litical implications around the turn of the new millennium. Argumentation is founded on the interpretation of the impacts of stakeholders’ interests on geo- politics under new societal conditions and the legacy of past energy produc- tion and logistics. Empirical evidence consists of material from the projects of Russian companies and the plans and politics of the Russian Government for developing the energy sector. The redefined borders and the geographical shifts of energy production have brought about the orientation of Russia’s energy development and interests towards the north. The former empire’s parts bordering on Russia in the west, Belarus and first of all Ukraine, have become problematic due to transit pay- ment conflicts. Consequently, Russian companies develop ports in North-West Russia as well as plan the construction of new oil and gas pipelines through the Baltic Sea Region. On the other hand, the northern location of the infra- structure plans is a geographical necessity, in the way that new oil and gas deposits lie in northern high-latitude zones. Energy stakeholders’ market-ori- ented interests greatly influence the country’s economic orientation to the ad- vanced economies and the global economy. Thus, Russia’s new energy geo- politics means economic integration and networking with partners (compa- nies, nations and economic areas) that are able to co-operate successfully in the economic sector.

  • EU and Russian Policies on Energy and Climate Change
    DIRECTORATE-GENERAL FOR EXTERNAL POLICIES POLICY DEPARTMENT DIRECTORATE-GENERAL FOR INTERNAL POLICIES POLICY DEPARTMENT A POLICY BRIEFING EU and Russian policies on energy and climate change Abstract EU-Russian energy relations are characterised by mutual interdependence. Within the EU, however, the level of Member States’ dependence on Russia varies largely according to Member States’ abilities to diversify their energy mix and their imports. This has created a fragmented internal energy market, as demonstrated by the wide range in gas prices among Member States. Energy supply diversification has become a key concern for the entire EU, although energy policies are still largely overseen by Member States. While Russia is likely to remain Europe’s principal energy supplier in the medium term, the importance of other crude oil and natural gas exporters, including Azerbaijan and Algeria, is likely to grow. The European Commission supports widening the possible range of sources, particularly given its antitrust investigations against Russian companies, which have exacerbated tensions. The EU and Russia are also divided by their environmental policies, stemming from a different environmental sensibility but also from the different availability of fossil fuels. Fighting against climate change, the EU has committed to reduce its overall greenhouse gas emissions by 20 % by 2020. To fulfil this promise, the EU has relied on the EU Emission Trading System, currently the largest international carbon market. Unlike Europe and its ecological considerations, Moscow has long been driven by more economic and geostrategic factors. Despite Prime Minister Dmitry Medvedev’s recent willingness to consider limiting carbon emissions and fostering investments in renewable sources, the country’s refusal to adhere to the second commitment period of the Kyoto Protocol and its environmentally unfriendly Arctic efforts confirm Moscow’s resistance to integrating climate issues in its policies.
