With over 16.6 trillion cubic meters of gas in explored and preliminarily estimated reserves, the Yamal Peninsula is a strategic oil- and gas-bearing province in Russia. Eventually, Yamal is expected to become one of Russia’s three main gas production centers, with a potential annual output of up to 310–360 billion cubic meters of gas.
Figures and facts
The Kharasaveyskoye field is located in the Yamal Peninsula north of the Bovanenkovskoye field, predominantly onshore and partly in the Kara Sea.
The field is classified as unique thanks to its enormous gas reserves, which amount to 2 trillion cubic meters (C1+C2 categories).
It is planned to produce 32 billion cubic meters of gas per year from its Cenomanian-Aptian deposits.
Gazprom will start full-scale development of the field in 2019, with the Cenomanian-Aptian deposits as the primary target. Gas production is slated to begin in 2023. The underlying Neocomian-Jurassic deposits will be developed later.
By now, Kharasaveyskoye is provided with the vital utilities, including a camp for shift workers and an auxiliary power plant.
Infrastructure and transportation
The project envisages the construction of a comprehensive gas treatment unit, a booster compressor station, clusters of producing gas wells, and transportation and power infrastructure. Offshore wells will be drilled from onshore locations.
In winter, materials and equipment will be delivered to the field by the Obskaya – Bovanenkovo railroad and a winter road from the Karskaya station. In summer, cargo deliveries to the Kharasavey port station will be made by sea and river transport.
In order to convey gas produced from the field, a 100-kilometer gas pipeline connecting Kharasaveyskoye and Bovanenkovskoye will be built. The gas will then be fed into Russia’s Unified Gas Supply System.
Gazprom places increased emphasis on maintaining a high level of industrial safety and preserving the unique Arctic environment. Kharasaveyskoye is characterized by complex geocryological conditions, including thick permafrost and high soil salinity, which makes it especially difficult to set up facilities in the area. In order to avoid the risks of permafrost melting, it is planned to widely use vapor-liquid cooling systems. To prevent permafrost from melting during gas production, wells will be constructed with thermally-insulated tubings and casings. Closed-loop water supply systems will help avoid soil and water pollution. The field’s linear facilities will be provided with special crossings for deer and wildlife migration.
