Full-scale development of Kharasaveyskoye field starts in Yamal Peninsula

A ceremony was held today in the Yamal-Nenets Autonomous Area to mark the launch of full-scale development of the Kharasaveyskoye field. Attending the event were Alexey Miller, Chairman of the Gazprom Management Committee, Dmitry Artyukhov, Governor of the Yamal-Nenets Autonomous Area, and heads of Gazprom’s relevant subdivisions and subsidiaries.

Vladimir Putin addressed the event participants in his opening speech via a conference call.

The Kharasaveyskoye field is the second most important field (after the Bovanenkovskoye field) in Gazprom’s Yamal gas production center. The Yamal center plays an essential part in the Russian gas industry of the 21st century.Gas production at the Kharasaveyskoye field is going to start in 2023. The estimated volume of gas production from the Cenomanian-Aptian deposits is 32 billion cubic meters per year. After this, the Company is going to proceed with developing the deeper-lying Neocomian-Jurassic deposits. While mostly lying onshore, the field also partly spreads into the waters of the Kara Sea. Wells for the offshore part of the field are going to be drilled from onshore.Today, the first truck convoy left the Bovanenkovskoye field carrying construction and supporting equipment to the Kharasaveyskoye field along a specially constructed seasonal road (winter road). Some 5,500 engineers and builders and 1,764 vehicles are going to be involved in the pre-development work.The pad-filling works for roads and production facilities are scheduled for 2019. In June 2020, the Company intends to start drilling gas producing wells.

“Today, we are starting full-scale development of the Kharasaveyskoye field. We chose design and engineering solutions that are as similar as possible to those that have been successfully applied in Bovanenkovo. This means that we can streamline our investment and operation costs.

Gas production in the field is going to be carried out using exclusively domestic equipment. As part of our operations in Kharasavey, we’ll start developing the shelf of the Yamal Peninsula, " said Alexey Miller.

 

Background

The Kharasaveyskoye field is located to the north of the Bovanenkovskoye field in the Yamal Peninsula. The field is unique in terms of its gas reserves that amount to 2 trillion cubic meters.

As of now, the field has a utility system with a camp for shift workers and an auxiliary power station.

The field’s Cenomanian-Aptian deposits are going to be the first development target. Gazprom plans to construct 236 gas production wells, a comprehensive gas treatment unit, and a booster compressor station, as well as a transport and power infrastructure.

In order to transport the gas produced at the field, a 106-kilometer gas pipeline connecting the Kharasaveyskoye and Bovanenkovskoye fields 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 unique Arctic ecosystems. The field is characterized by complex geocryological conditions, including thick permafrost and high soil salinity, which makes it especially difficult to set up industrial 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 heat-insulated tubings and casings. Closed-loop water supply systems will help avoid soil and water pollution. The field’s linear facilities will be equipped with special crossings for deer and wildlife migration.
