10/18/2009 Editorial
G.V. Shevchenko (Gasoil Press)

This new issue of The Gas Industry of Russia quarterly digest presents a series of articles focused on gas production, transportation, and storage. This technology chain appears to be immune to economic slowdown and crises.

12/01/2008 The Eastern Gas Programme - early development phase*
A.G. Ananenkov (Deputy Chairman, Gazprom)

The Eastern Gas Programme adopted by the Russian government is set to guide the gas development strategy for the country's Eastern regions. Given the appropriate economic conditions are established, the resources in the Russia's East offer opportunities to set up four new major gas production centres -Sakhalin, Yakutian, Irkutsk, and Krasnoyarsk - which are likely to ensure over 200 Bern annual gas output by 2030.

10/31/2009 Natural gas production in Tyumen region: economic-and-mathematic modelling and forecasting

A.A. Afanasyev (Central Economics & Mathematics Institute, RAS)

In terms of statistical criteria, the proposed production functions of gas sector operations regarding the activities in entire Tyumen region and by Gazprom's subsidiaries appears to adequately describe gas production processes which are essentially predictable. There are good applications available for production economics analysis, planning, and forecasting - with all such areas believed to be useful for both related government authorities and domestic oil and gas companies including Gazprom. In particular, such functions can be applied to development of Russia's new energy strategy and gas industry investment programmes.

10/31/2009 Comprehensive approaches to gain performance benefits with Urengoy development

G.A. Lanchakov, A.N. Dudov, and V.A. Stavitsky(Gazprom Dobycha Urengoy)

Gazprom Dobycha Urengoy has been involved in systematic, and wide-ranging, innovations regarding Urengoy field development technologies aiming to boost its overall performance. Key aspects include sustaining target production levels and protection of vulnerable nature of this Far North area. At present, Urengoy incorporates over 2,500 gas, condensate, and oil fields thereby making these activities the most critical area for upstream operations.

10/31/2009 Oil production and treatment in Urengoy
S.V. Sorokin, O.P. Kabanov, and V.M. Tugarev (Gazprom Dobycha Urengoy)

While over 30 years of pilot and commercial oil fringe operations in Urengoy field, three sites have yielded more than 11 million t of oil and 15 Bcm of gas. Oil fringe production under normal depletion curve features direct reliance of flow on operation of gas and condensate fields. Under formation conditions, this relationship is attributable to hydrodynamic links between oil and gas/condensate production zones, with similar operating links existing between oil and gas field processing facilities.

11/02/2009 Models for gas hydrates decomposition

V.A. Istomin(NOVATEK) and V.G. Kvon(VNIIGAZ)

Experimental data on kinetics of gas hydrates decomposition at atmospheric pressure (after pressure release in a PVT chamber) evidences several peculiar features: the initial stage can follow several metastable phases and kinetic data variability depending on driving force. Different decomposition mechanisms and their competition, driven by particular pT conditions, are possible. Development of such models is believed to be central for prospective gas hydrate technologies targeted by gas industry innovation programmes.

11/02/2009 Oil fringe development optimisation in gas/oil fields

A.V. Akhmetzyanov and I.I. Ibragimov(V.A. Trapeznikov Economy Management Research Centre, RAS),and A.I. Yermolayev (Gubkin Oil & Gas University)

Oil fringe zones in gas/condensate fields are typically confined to hydrocarbon deposits featuring hard-to-recover reserves. There are several underlying causes, with gas/oil and water/oil contact zones being the most significant. Numerous researchers evidenced largely ineffective development of oil fringe areas while natural flow operations. The search for more viable bed stimulation technologies is believed to be critical, along with production optimisation. This paper addresses one of approaches in this area.

11/04/2009 Automatic location of annular welds assisted by gas pipeline magnetic diagnostic data
V.A. Povagin (Spetsneftegaz) and G.S. Korzunin (Institute of Metals Physics, RAS)

This new method offers automatic location of annular welds in pipelines. It is built around diagnostic data obtained by internal inspection of major gas pipelines using magnetic pigs – flaw locators. The method employs numerical modelling of several quality indicators recognised from welds' magnetic images entered for expert-assisted flaw recognition. This paper summarises and tests actual results produced by this innovative algorithm.

11/04/2009 Controlled blast assists gas pipeline crossings construction
O.A. Stepanenko, V.A. Grabovets, A.G. Arefiev, B.V. Smolyakov, and B.V. Ioffe (Gazprom Transgaz Samara)

Gazprom Transgaz Samara offers an innovative trenchless pipelay technology, which provides channel for protective pocket used while construction and workovers in road and rail crossing points. This method employs controlled-blast energy. The paper addresses elements of explosion theory with regards to soils, and highlights rule-of-thumb relationships used for assessment of elongated charge weight. The authors propose a simplified method offering high accuracy of explosion outcome assessments, given the preset hole geometry.

11/04/2009 Geological and hydrochemical monitoring of Inchukalns storage tightness

A. Davis, I. Shcherbitskis, E. Birgers, and E. Kovalevskaya(Latvijas Gaze); O.G. Semenov (VNIIGAZ)

For many years, sealing properties of this storage facility has been tested by regular hydro/gas/chemical and geophysical surveys undertaken since 1968, when it was brought online. The monitoring system incorporates depth observations, and a number of surveys, combined with geophysical monitoring, and sustains reliable geological and environmental monitoring of the facility, to effectively test and confirm its sealing properties.

11/04/2009 Gas storage environmental and geochemical surveys

N.A. Gafarov and S.A. Khan (Gazprom), A.S. Derkach (Gazpromgeofizika); V.F. Shulayevand and S.G. Glaz (NPF Orenburggazgeofizika)

Operating practices with storage facilities constructed in depleted gas fields or watered reservoirs indicate that underperformance of individual wells typically leads to excessive gas accumulations in upper zones. Relatively small, but long-lasting behind-the-casing gas flows or gas leakages could lead to pony gas accumulations causing environmental and safety hazards. The required geochemical studies should be repeated at least every third year, to identify locations of such gas accumulations and migration paths.
