The 50th anniversary of Gazovaya Promyshlennost journal
A.G. Ananenkov (Gazprom)
l proudly come to its 50th anniversary. But I I believe, rather than this age alone, the greatest tribute should be paid to huge contribution of its editors, and authors who represent the most significant part of the gas engineering society, both in Russia and outside in countries with extensive focuses on the Russian energy sector.
The Russian resource base - a key to gas sector long-term future
A.G. Ananenkov (Gazprom)
Russia is a leading gas nation globally, in terms of its available in-place resources, explored gas reserves, together with production, transport, and export flows. Only in terms of gas consumption Russia is ranked the second nation, giving way to the US, although still consuming more gas than all the EU-15 countries altogether. Successful development of the Russian gas industry is driven by two main factors. First, by enormous resource potential - an inestimable national endow. Second, by unique production, scientific, technical and human potential which is created in this area and accumulated by generations. The domestic gas sector is essential for the national economy and countryís energy security.
Justification of Yen-Yakhin field product composition
A.G. Kasperovich (Gazpromrazvitie), O.P. Kabanov and V.A. Stavitski (Urengoigazprom), V.V. Prytkov and D.A. Rychkov (TyumenNIIGiprogaz)
TyumenNIIGiprogaz is coming with its advanced method designed for detailed analysis of components present in the reservoir fluid and gas/condensate production flows, as well as in field treatment and processing yields. This method was central for identification of initial reservoir fluid composition for En-Yakhin field, and to estimate expected compositional changes in the produced flow over the entire production period. The approach employed for this comprehensive task is analysed in detail.
Geological and geophysical modelling of new prospects
S.M. Karnaukhov (Orenburggazprom), M.A. Politykina and A.M. Tyurin (VolgoUralNIPIgaz), S.M. Poberezhski, V.I. Dnistryanski, and V.I. Gorelikov (Orenburggazprom), V.V. Drozdov, Z.I. Zenkina, and R.A. Syumbayeva (VolgoUralNIPIgaz)
Since 1999, Orenburggazprom has been involved in digital geological/geophysical modelling of various oil and gas prospects. The first promising results have been obtained with Vershinov play using Pangeya - an advanced data interpretation package.
A laser-based information and metering system for moisture and hydrocarbons dew-point monitoring
A.M. Derevyagin (NPF Vympel)
Since recent years, the KONG family gas dew-point metering systems have been increasingly used in gas field and pipeline operations - both in Russia, FSU, and in Western Europe. Experience with dew-point measurements to date has promoted the emergence of second-generation KONG-Prima-10* dew-point analysers featuring numerous advantages. In fact, this new instrument comprises an information/metering system designed for precise dew-point measurements indicating water and heavy hydrocarbons in natural and associated gas streams, under a range of compositions and operating pressures.
Two-dimensional analysis of elastic stress patterns in a borehole zone
A.M. Svalov (IPNG, RAS)
Well casing quality, bottom hole conditions, and well performance - all are driven, combined, by stress patterns in rock mass in borehole proximity, and by emergence of stress zones. A traditional approach to analysis of elastic stress patterns which is built around one-dimensional rock elastic equilibrium equations offers only an averaged stress distribution, with no consideration given to formation's roof and bottom implications, i.e. impacts of impermeable formation boundary zones with different properties and loading conditions of surrounding rock. Such assessments are largely unsuitable to quantify the problem, for more point-specific calculations. This twodimensional approach is believed to provide more value.
Automated strength analysis of buried pipelines
V.V. Aleshin, V.E. Seleznev, and V.V. Kobyakov (NPO VNIIEF – VOLGOGAZ)
This finite element model-based ANSYS software package was employed within a numerical approach to development of automated tools focused on buried pipeline deformation status and pipe strength assessment. High performance of this approach is evidenced by successful management, in 2001 - 2003, of several gas transmission challenges associated with pipeline status evaluation and security analysis covering the most critical system segments run by SPP-DSTG, an international gas transmission company.
Dispatching flows in international gas transit systems
V.G. Gerke (Gazprom)
Four interconnected dispatching levels were designed to ensure efficient and uninterrupted Gazprom facility operations. This task incorporates process information management and operating targets communication with follow-up monitoring. Gazprom's Central Operations and Dispatch Department (CODD) focuses on interconnections between its own gas production and pipeline supervisory control divisions, combined with independent Russian producers and foreign gas companies.
Development of equipment diagnostics framework
I.I. Gubanok and V.V. Salyukov (Gazprom), C.P. Zaritski (Orgenergogaz)
Gazprom is strategically focused on a phased transition from traditional operating maintenance principles to an innovative condition-driven scheme. This goal is believed achievable through the development and introduction of a unified equipment diagnostic service and maintenance framework, across the entire gas sector, assisted by a comprehensive database.
Thermal imaging and TV tools assist pipeline burial depth measurements
V.N. Moiseyev and V.N. Rozov (Spetsgazdiagnostika), A.G. Arefiev (Samaratransgaz), V.N. Dedeshko and V.V. Salyukov (Gazprom)
In Russia's Guidelines to Comprehensive Management of Major Gas Pipeline Diagnostics, positional changes of individual pipeline sections are considered to be among the key technical signposts. During helicopter-assisted inspections of several pipeline segments operated by Samaratransgaz, a series of images was produced using Spetsgazdiagnostika's thermal imaging and TV-based instruments. Subsequent image analysis indicates exact position of pipelines under inspection.
Gas pipeline stress corrosion: Diagnostic techniques, scope, and performance
V.V. Kharionovski (VNIIGAZ)
Over the past decade, pipe metal stress corrosion cracking (SCC) has grown into one of the key factors which predetermines the general technical status of Russia's major gas pipelines. Unlike the early 1990s when SCC-caused emergencies were only limited to northern areas, in the latter part of the decade their geography was largely spread into West Siberia, the Urals, and regions of central Russia. Therefore, the SCC issue has become a priority for gas transmission facilities, country-wide.
New technical regulations address energy conservation and environmental control
B.V. Budzulyak and I.Sh. Saifullin (Gazprom)
More than a year-and-a-half have passed since the adoption of Technical Regulations Federal Law 184-FZ dated December 27, 2002. Since then, Gazprom has come with its proposals regarding the Russian government's draft programme concerning the recommended practices, and company's representatives were subsequently entered into the emerging Coordinating Board for Best Practices in the Oil and Gas Sector.
Environmentally compliant ceramic drives for gas turbine equipment
S.A. Fursenko (Lentransgaz) and A.V. Sudarev (Boiko NITS KTD)
Domestic engineering companies are presently challenged by a pressing need for introduction of high-tech equipment including various gas sector applications. Regarding the quality standards, this equipment should be competitive enough to ensure Russian companies' successful bidding both in Gazprom's domestic tenders and internationally. Such technological advancements have been successfully implemented with KGTD-2.5 ceramic gas turbines with 2.5 MW power rating. These devices are viewed as a major breakthrough - in terms of performance, environmental compliance, reliability, and costs.
Waste utilisation: A way to cut GHG emissions in the Baltic area
S.V. Markin (Gazprom), E.B. Bukhgalter and B.O. Budnikov (VNIIGAZ), O.A. Budnikova (MGUP)
Extensive environmental examination programmes undertaken by Gazprom, both domestically and outside Russia, indicate that the company's project design organisations often lack sufficient knowledge of local legal norms and regulations as well as environmental guidelines typical of a country in question. In particular, special emphasis is now placed on global experience with recycling domestic wastes - mainly packaging materials - thereby contributing to easing the global climate challenge.
