Bovanenkovo

 

Significance

The Yamal Peninsula is a strategic oil- and gas-bearing region of Russia. Explored and preliminary estimated gas reserves exceed 16.7 trillion cubic meters there. In future, Yamal will become one of the three main Russian gas production centers with a potential annual output of 310–360 billion cubic meters of gas.

Reserves

Bovanenkovskoye is the largest field in the Yamal Peninsula. Its explored and preliminary estimated gas reserves amount to 4.9 trillion cubic meters.

Development

The Cenomanian-Aptian deposits are a paramount development target at Bovanenkovskoye. Gas production is planned at 115 billion cubic meters annually. Overall, there will be three upstream facilities in operation. Two of them have been already brought online: the first one – in 2012 (planned output – 60 billion cubic meters of gas per year), the second one – in 2014 (30 billion cubic meters). Gas production is increased gradually, depending on the market demand.

In future, Bovanenkovskoye is to see gas extraction ramped up to 140 billion cubic meters per year through the development of Neocomian-Jurassic deposits.

Gas pipelines

In order to feed gas from Yamal into the Unified Gas Supply System (UGSS) of Russia, Gazprom is building a new gas transmission corridor from Bovanenkovo to Ukhta.

In 2012, the Bovanenkovo – Ukhta gas pipeline was commissioned. At present, the Bovanenkovo – Ukhta 2 gas pipeline is under construction.

Innovations in action

Coping with the difficult environmental and climatic conditions of Yamal, Gazprom employs high-performance and safe innovative technologies and engineering solutions on the Peninsula. Many of them have been developed on Gazprom's order specifically for Yamal by the leading Russian research institutes and companies.

Particularly, Russia's first integrated infrastructure for gas extraction from the Cenomanian (520–700 meters deep) and Apt-Albian (1,200–2,000 meters deep) deposits is in operation at Bovanenkovskoye. This approach helps significantly save on pre-development costs and boost production efficiency. Producing wells are drilled by the fifth-generation Ekaterina rigs manufactured in Russia in accordance with the best design practices. Gas is treated through the state-of-the-art and eco-friendly method of low-temperature separation with the use of domestic turbo expanders.

The onshore gas transmission pipelines of the Bovanenkovo – Ukhta system are for the first time ever operated at a working pressure of 11.8 MPa (120 Atm), which helped use less metal for the project. The unique 1,420-millimeter pipes utilized during the construction process were made in Russia of K65 (X80) steel with a smooth interior coating.

In order to deliver materials and equipment to Bovanenkovskoye, Gazprom built the one-of-a-kind Obskaya – Bovanenkovo railroad stretching over 500 kilometers. When constructing the railroad, the Company laid a unique bridge over the floodplain of the Yuribey River: the bridge is the world's longest (3.9 kilometers) beyond the Polar Circle.

Environmental care

While building various facilities, Gazprom is primarily concerned with preserving the unique nature of Yamal. Consequently, technological facilities occupy the least possible area.

In order to reduce the impact on the permafrost, such technologies as vapor-liquid heat stabilizers and thermally insulated pipes for wells are applied. In-plant recycling systems are used for eliminating pollution of water reservoirs and soil.

Special crossings over utility lines are set up for free migration of deer. The environmental situation is continuously monitored.
