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.

Figures and facts

Bovanenkovskoye is the largest field in the Yamal Peninsula in terms of explored gas reserves.

Its initial gas reserves amount to 4.9 trillion cubic meters.

Bovanenkovskoye’s design gas production capacity is 115 billion cubic meters per year. In future, gas extraction is expected to reach 140 billion cubic meters per year through the development of Neocomian-Jurassic deposits.

Development

The primary development target at Bovanenkovskoye is the field’s Cenomanian-Aptian deposits.

The deposits are developed by three gas production facilities, which were consecutively brought into operation in 20122014, and 2018.

In order to feed gas from Yamal into Russia’s Unified Gas Supply System, Gazprom built a new gas transmission corridor extending from Bovanenkovo to Ukhta. The Bovanenkovo – Ukhta gas pipeline became operational in 2012, and Bovanenkovo – Ukhta 2 came onstream in 2017.

Technologies

Overcoming the Yamal Peninsula’s harsh climate and environment, Gazprom has made Yamal its launch pad for efficient, safe and innovative technologies and technical solutions. Many of them have been developed by leading Russian research institutes and companies specifically for Yamal on the Company’s order.

For instance, 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. Every facility operating at Bovanenkovskoye uses modern automation systems and lightly manned technologies.

For the purpose of transporting gas via Bovanenkovo – Ukhta and Bovanenkovo – Ukhta 2, the onshore gas pipelines were for the first time in history designed for a working pressure of 11.8 MPa (120 atm), which helped use less metal for the project.

The unique domestically-produced 1,420-millimeter pipes used in construction are made 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 for over 500 kilometers. When constructing the railroad, the Company laid a unique bridge over the floodplain of the Yuribey River: the 3.9-kilometer bridge is the world’s longest beyond the Arctic Circle.

Environment

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

Impacts on the permafrost are reduced through such technologies as vapor-liquid heat stabilizers and thermally insulated pipes for wells. In-plant water recycling systems are used to eliminate 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.
