The Chayandinskoye oil and gas condensate field is located about 150 km west of the city of Lensk, on the territory of the Mirnensky and Lensky districts of the Republic of Sakha. The development strategy for gasification and gas supply throughout the Far East and Eastern Siberia is determined by the basic document - the state Program. It is aimed at creating in the regions a unified system for the extraction, transportation of fuel and providing them, taking into account the possible export of the markets of China and other Asia-Pacific countries. The Eastern program was approved in autumn 2007 by order of the Ministry of Industry and Energy of the Russian Federation.
Organizational matters
The coordination of the necessary actions in the course of implementation was entrusted by the Government of the Russian Federation to Gazprom. The Chayandinskoye field under the Program is one of the promising centers for the extraction of raw materials. At the same time, new gas production zones are being formed in the eastern part of Russia. This, in particular, the Irkutsk, Krasnoyarsk and Kamchatka centers, as well as the region of. Sakhalin (shelf areas). A key factor in the organization of Gazprom’s work is an integrated approach. It consists in the synchronous commissioning of facilities, including the formation of a gas production center in Yakutia. The creation of new facilities, as well as the process of processing and transportation of hydrocarbons, is closely interconnected with other state infrastructure projects in the Republic of Sakha, which are financed from the federal budget. To date, the network, transport and energy supply sectors of the economy are actively developing in Yakutia. At the same time, special attention is paid to optimality in making decisions that can provide the maximum number of emerging needs, including for gas workers. The full development of the gas production center in Yakutia is supported by the high level of professional training of the involved personnel. Personnel also have the opportunity to receive advanced training directly in the Republic of Sakha. For this, the government of Yakutia, together with Gazprom, created a specialized department at the North-Eastern Federal University in Yakutsk.
Partnerships
The strategic partner of the Republic of Sakha is Gazprom. The interaction of the parties is carried out and regulated by the Cooperation Agreement and the Gasification Agreement. The implementation plan of existing projects of OJSC in the territory of Yakutia includes not only fuel supply, but also stable economic development of the region.
Resources
According to preliminary estimates, the prospective reserves of Sakha’s raw materials are 10.4 trillion m³. The basis for the formation of the production center and its effective development is the Chayandinskoye oil and gas condensate field. The volume of pledged resources of the C1 + C2 group is 1.2 trillion cubic meters of gas, 791 thousand tons of oil and condensate.
Location
A characteristic feature of the Chayandinskoye field, however, like other natural deposits located in Eastern Siberia, is the presence of specific thermobaric reservoir conditions. In addition, the area has a complex geological structure. The gas produced in this area is distinguished by its multicomponent composition, as well as a high helium content. The development of the Chayandinskoye field will be carried out in the harsh climate of the Republic of Sakha. The temperature here in winter can drop below minus 50 ° . The pipeline route from the Chayandinskoye field in Yakutia to the city of Vladivostok is planned to be laid through mountainous, swampy, and seismically active areas.
Permits
Gazprom is authorized to use the resources laid in the bowels of the Chayandinskoye field. This organization right was granted by order of the Government of Russia on April 16, 2008. To ensure the effective development of a center for the extraction of raw materials in the Republic of Sakha and the optimal use of the fuel and transport system, it is planned to connect all the resources of this region to work. Since December 2011 OAO Gazprom also has a license permitting the use of the subsoil of the Verkhneveluchanskoye, Sobolokh-Nejelinsky, Srednetyungskoye and Tas-Yuryakhskoye fields located in the region.
Program Implementation
In September 2010, the commission for the development of hydrocarbon deposits approved a technological scheme in accordance with which the Chayandinskoye field will be developed. The final project on issues related to the justification of investments in the preparation of deposits, processing of raw materials and transportation was approved in October 2012. To this day, exploration work is ongoing at the Chayandinskoye field, the geometry of the deposits, the features of saturation of productive horizons, and the geological structure of the field are being studied. generally. More than half of the resources of raw materials laid in the bowels have already been transferred to the group of explored deposits. The completion of all the work necessary for the implementation of the program is planned for 2015. A set of measures for the development and development of the field is organized by the established branch of the Chayandinsky Oil and Gas Production Department of Gazprom Dobycha Noyabrsk LLC.
General information
The raw materials extraction center in Sakha is connected with the Irkutsk unified fuel and transportation system under the name “Power of Siberia”. With its help, the supply of raw materials extracted in these areas will be carried out through Khabarovsk to Vladivostok. The system got its name following the results of a specially held competition. First of all, it is planned to build the Yakutia-Khabarovsk-Vladivostok gas pipeline to transfer raw materials over long distances. After that, the centers in Sakha and Irkutsk will be connected. The route of the main gas transmission system, the main centers of which will be the Kovykta and Chayandinskoye fields, will be laid along the route of the existing oil pipeline with the direction “Eastern Siberia - Pacific Ocean”. This solution can significantly reduce energy costs, as well as infrastructure. The GTS path will extend through mountainous, swampy, and seismically active areas.
Development prospects
The creation of a gas production center in the Republic of Sakha will be the beginning of a large-scale development of the fuel industry in the East of Russia. The construction of the gas pipeline and the development of the Chayandinskoye field are not the only tasks set by the Management Company. In addition, it is planned to simultaneously produce plants for the processing of raw materials and helium production in Belogorsk. The raw materials, which are rich in the Chayandinskoye field, can be used to create gas chemical industries. This can subsequently attract investment by core companies. The main goal of the Yakutia gas production center is to provide consumers with raw materials in the territory of the Russian Federation. For this, all necessary measures will be taken to achieve the long-term development of the fuel supply of the Republic of Sakha and other regions of the Far East. The opening of the Yakutsk center will also be a starting point in the creation of a new complex for the extraction of raw materials in the East of Russia, in which the Kovyktinskoye and Chayandinskoye deposits will be of key importance. The center will be formed to organize the export of raw materials abroad. To this end, Gazprom plans to build a plant specializing in the production of liquefied gas in Vladivostok in the near future . At the moment, the project is at the stage of developing justifications for the investments necessary for construction.
Features of the Irkutsk Center
The next stage in the development of the gas program will be the development of the Kovykta gas field. It is located in the Irkutsk region. Kovykta is a rather promising gas field discovered in 1987. It is located in the Kazachinsko-Lensky and Zhigalovsky districts, 450 km north-east of Irkutsk. The field is located in an uninhabited area. The territory is an alpine plateau with dark coniferous taiga. Some areas of Kovykta are in the permafrost zone. The local relief is dotted with numerous canyons. The climate is sharply continental, severe. According to preliminary estimates, the natural gas deposits of the Kovykta field are approximately 1.9 trillion. m³ of pure gas, 115 million tons of gas condensate, 2.3 billion m³ of helium. To implement the development program, the construction of the highway will be organized. Its total length will be more than 550 km along the Kovykta – Sayansk – Angarsk – Irkutsk highway. It is also planned to build a helium and gas separation plants.
