  • The Myth of Cheap Russian Gas
    Founded by H.S.H. Prince Michael of Liechtenstein The myth of cheap Russian gas Dr. Frank Umbach Russia & Central Asia Sept. 05 2017 The desolate Arctic landscape of Gazprom’s Bovanenkovo gas field on the Yamal peninsula, 4,300 kilometers away from West European customers (source dpa) A frequent but unquestioned claim about the controversial Nord Stream 2 (NS-2) gas pipeline and the latest round of American sanctions against Russia is that Russian natural gas is much cheaper than that of rival suppliers. This particularly applies to liquefied natural gas (LNG) exports from shale producers in the United States. According to this argument, the European Union should leave it to the market price to determine which gas suppliers European importers choose. But Russia’s cheap gas from its mature fields in Western Siberia are rapidly dwindling, while output from the new gas fields in the Yamal peninsula must be heavily subsidized to offset higher production and transport costs. This question is far from academic at a time when gas prices in Europe and Asia are declining rapidly, and the LNG exports from the U.S. are getting cheaper. In fact, Europe is now entering a new era when Russian gas (if not subsidized) is no longer cheap, and LNG from the U.S. and other producers is no longer expensive. Different product From 2012 to 2016, the average price of Russian natural gas exports to Europe dropped from more than $400 per 1,000 cubic meters (cm) to just $167. That significantly undercut prices at Europe’s main gas hubs (the Netherlands’ TTF and Germany’s NCG), which averaged about $243-$245 per 1,000 cm last year.

The analysis of the data gave us the possibility to study the dynamics and hydrological structure of the southwestern Kara Sea basin. The main elements of the gen eral circulation are the following: the Yamal Current, the Eastern Novaya Zemlya Current, and the St. Anna Trough Current. All these currents are topographically controlled; they flow over the bottom slopes along the isobaths. The Yamal Current begins at the Kara Gates Strait and turns to the east as part of the cyclonic cir culation.

  • Nenets Reindeer Herders on the Lower Yenisei River: Traditional Economy Under Current Conditions and Responses to Economic Change
    Nenets reindeer herders on the lower Yenisei River: traditional economy under current conditions and responses to economic change Konstantin B. Klokov The article is dedicated to the problems of survival and development among the aboriginal peoples of northern Russia in the context of current conditions. Data collected in the western part of the Taimyr Autonomous District allowed us to divide the non-sedentary population of this territory into three groups differentiated by overall way of life, land use and economic “calendar.” These groups are: the nomadic reindeer herders of the tundra (about 250-300 people), the semi-nomadic fishermen- herders of Yenisei delta (about 500), and t6e nomadic herders of the forest-tundra (300-350). The economy and ways of life of the three non-sedentary groups are described. Communities whose traditional subsistence base is reindeers have entered a crucial period. In response to the pressure of the dominant society, these peoples have three possible strategies: isolation, passive adaptation and active adaptation. Only the last strategy can preserve their culture, and create a “neoculture”. Now, however, passive adaptation predominates. The mutual, bi-directional process of cultural integration needs to reinforce positive aspects of acculturation and promote active, rather than passive, adaptation. A necessary condition for this is the appearance among the Nenets of an intermediate social stratum which maintains close links to nomadic reindeer-husbandry and is simultaneously integrated into the dominant society.

It is also the country' s largest investment project in Russia, widely hailed as a fine example of China-Russia cooperation. CNPC participates in the operation of the project throughout the entire industrial chain and has become a vital player in the international LNG industry. Located in the Arctic Circle of the Yamal Peninsula in Russia, the Yamal project is an integrated project encompassing oil and gas exploration and development, natural gas processing, liquefaction, marketing and shipping. CNPC, China' s Silk Road Fund, Novatek and Total hold 20%, 9.9%, 50.1% and 20% of the equity shares of the project, respectively.

The peatlands of the WSL are of major importance to high-latitude hydrology, carbon storage and environmental history. Analysis of the existing Russian data suggests that the mean depth of peat accumulation in the WSL is 256 cm and the total amount of carbon stored there may exceed 53,836 million metric tons. A synthesis of published and unpublished radiocarbon dates indicates that the peatlands first developed at the end of the Last Glacial, with a rapid phase of initiation between 11,000 and 10,000 cal yr BP. Initiation slowed after 8000 cal yr BP and reached a nadir at 4000 cal yr BP. There has been renewed initiation, particularly south of 621N, following 4000 cal yr BP. The initial development of peatlands in the WSL corresponds with the warming at the close of the Pleistocene. Cooling after 4000 Cal yr BP has likely led to increased permafrost and increased peatland development particularly in central and southern regions.

  • Gazprom's Investment Program Can Best Be Understood As a Way to Employ the Company's Entrenched Contractors at the Expense of Shareholders
    Received by NSD/FARA Registration Unit 06/24/2021 6:14:07 PM INVESTMENT RESEARCH ^ SBERBANK CIB RUSSIA | OIL AND GAS MAY 2018 Russian Oil and Gas Tickling Giants ■ Lukoil has finally outlined its capital allocation policy simply and clearly. The company will share the majority of its free cash flows with shareholders, either through dividends or buybacks. It will reinvest 80% of its capex in the Russian business, where it enjoys greater competencies. We believe that if the management follows through on its promises, the market will have no cause to demand the current double-digit free cash flow yield from the shares. We reiterate our BUY recommendation. Our $85 target price implies a circa 9.5% free cash flow yield at $65/bbl oil. Lukoil shares present an especially good bargain whenever the market offers them at or below the oil price. ■ Gazprom's investment program can best be understood as a way to employ the company's entrenched contractors at the expense of shareholders. The three major projects that will eat up half of the capex in the next five years - Power of Siberia, Nord Stream-2 and Turkish Stream - are deeply value-destructive. Moreover, we expect them to be followed by a large-scale revamp of the company's trunk pipeline infrastructure, which is aging fast. Such a project could keep capex elevated indefinitely. We retain our opportunistic BUY recommendation on the hope that a political reshuffle could bring about a reform effort, though we concede the chances are slim. ■ Rosneft has announced it will aim to lower capex and reduce net debt by $8 bln this year, or about 10%.

  • Sources of Natural Gas Within Permafrost North-West Siberia

Moscow State University - 119899, Moscow, Vorobievy Gory, MGU, Geological Faculty, Department of Geocryology. e-mail: [email protected] Abstract Various aspects of sudden natural gas blowouts from within the permafrost sections of deep (greater than 300 m) wells at Yamburg and Bovanenkovo gas fields (northwest Siberia) are presented. Topics covered include: gas geochemistry, blowout intensity (gas flow rate), depth interval and permafrost rock peculiarities in places of these gas releases. The results are compared with similar studies in other polar regions. Although microbial gas is widespread within permafrost, thermogenic gas can also occasionally migrate from deep gas reservoirs along faults or be present locally in areas of gas reservoirs within the permafrost section. Gas can be preserved within permafrost in a free state as well as in hydrate form throughout the permafrost zone. Introduction are prevented by heavy drill mud. Recent changes in drilling procedure in the Yamal gas fields (planned to Sudden gas blowouts originating within permafrost be operated by ÒGazpromÓ in near future) have provi- intervals have been encountered during well drilling in ded an opportunity to study these gas releases in more different parts of the polar region (Yakushev and detail.
