Rainer Hartmann (Head of E.ON Ruhrgas AG Moscow Office)

This 4th issue of Gazovaya Promyshlennost Digest maintains a 2006 series of focused publications derived from the original journal and targeted on its readers world-wide.

05/31/2009 Marine gas hydrates: geology, geochemistry, and development prospects
Ye.V. Perlova, S.A. Leiniv, V.S. Yakushev, and N.A. Makhonina (VNIIGAZ)

In the near future, accumulations of marine gas hydrates - which are supposed to have a significant hydrocarbon potential - could become the most promising type of unconventional natural gas resources. At the same time, gas hydrates can be indicative of far deeper hydrocarbon reservoirs as well. Russia's forecast potential for marine hydrates is much higher than that for inland hydrates. The Black Sea and the Sea of Okhotsk are this country's key areas of marine gas hydrates exploration and pilot production.

05/31/2009 Modelling gas hydrate thermal stimulation: well hole temperature gradient while heat agent injection
K.S. Basniyev, S.N. Boziyev, B.I. Medvedev, and V.B. Nagayev (Gubkin Oil & Gas University)

When analysing the applicability of thermal methods for gas hydrates recovery, two key issues typically emerge: the choice of heat source, and how this heat can be delivered to target area. Several existing filed development technologies use heat-transfer processes to cool gas media. It is therefore believed promising to combine such cooling processes with the use of generated heat for methane hydrates decomposition. It is obvious that the efficiency of heat transfer largely depends on heatexchange area and, as such, on injecting well geometry. This paper considers a model for one chosen injection well configuration.

05/31/2009 Prospects for gas hydrates development
K.S. Basniyev, A.I. Yermolayev, V.V. Kulchitsky, and A.V. Shchebetov (Gubkin Oil & Gas University)

Gas hydrates development is increasingly drawing attention worldwide. Above all, this focus is closely interrelated with successful exploration drilling in gas hydrate accumulation areas along with recent advances regarding the studies of gas hydrate formation and decomposition in porous media. Over the past decade, several major gas hydrate accumulations have been discovered in Japan, Canada, and India. First gas hydrate samples have been recovered, and potential commercial gas production from hydrate accumulations has been initially tested. However, a cost-effective way of gas hydrates development still has to be found.

05/31/2009 Metastable states of gas hydrates
V.A. Istomin (Moscow Physical and Technical Institute), V.G. Kvon (VNIIGAZ), and V.A. Durov (Moscow State University)

Since recent years, most authors have been attributing the metastable states of gas hydrates to the so-called self-preservation phenomenon. In fact, many different metastability effects in hydrate systems can exist. Apart from the academic interest, research activity in this area can also bring the significant commercial results in the nearest future.

05/31/2009 Self-preservation phenomenon of gas hydrates
V.A. Istomin, V.S. Yakushev, and N.A. Makhonina, V.G. Kwon (VNIIGAZ); E.M. Chuvilin (Moscow State University, MSU)

The self-preservation phenomenon means that gas hydrates may exist in metastable state for prolonged time. The self-preservation phenomenon in gas hydrates paves the way to wide-scale use of various hydrate technologies in the oil and gas sectors. At present, this area is focal for R&D centres in the United States, Norway, Canada, Russia, Japan, and other countries of the world.

05/31/2009 Gazprom’s geological exploration performance in offshore Arctic areas
B.A. Nikitin and V.S. Vovk (Gazprom), A.Ya. Mandel and V.A. Kholodilov (Gazflot)

Russia's offshore zone comprises vast, but a largely undeveloped promising area accumulating huge resource potential for the oil and gas sector. Initial cumulative gas, condensate and oil reserves account for over 45% of World Ocean totals. Arctic seas - such as the Barents, Pechora, Kara, Laptev, East Siberian, and Chuckchee seas - hold the greatest development potential, and 85% of total offshore resources discovered to date are concentrated in the Barents, Pechora, and Kara seas.

05/31/2009 Subsea production system operations in shallow waters of freezing seas
S.I. Shibakin (LUKOIL)

Subsea production systems have been widely accepted for gas and liquids production in shallow zones of offshore fields in freezing seas, since such systems offer significant reduction in capital costs involved in field facility construction. Continuous, year-round development well drilling has been tested to boost the overall operating efficiency in such conditions. Innovative mobile, ice-resistant drilling platforms are believed to help achieve this goal.

05/31/2009 In-situ coal gasification technology
E.V. Kreinin (Promgaz)

Environmental friendly thermal power plants have become quite common to the West. Domestically, an underground coal seam gasification technology (or in-situ coal gasification) has been under development for some 50 years, and the success to date is evidenced by its "clean" benefits at all implementation phases - from production, transportation and storage to a burner tip. This technology is believed to provoke keen interest in both the power and the coal sectors.

05/31/2009 Flared gas: How to generate power and utilise combustion products for CO2 recovery
V.E. Finko and V.V. Finko (NTF)

These innovative technologies incorporate utilisation of LP petroleum gases - which are normally flared - for electricity generation and extraction of carbon dioxide from flue gas for subsequent injection into beds to enhance oil recovery. Progressive phasing out of gas flaring is expected to reduce the environmental loads and help Russia meet its Kyoto commitments. Given the relatively short payback periods for such energy installations (about 2 years), it is believed essential to set up a legal framework for government-driven, accelerated abandonment of flaring operations in oil and gas fields, presumably with the widest achievable coverage in the energy sector.
