Bovanenkovo

 

Strategy

In January 2002 the Gazprom Management Committee identified the Yamal Peninsula as the region of the Company's strategic interests. Commercial development of the Yamal onshore and offshore fields will yield up to 360 billion cubic meters a year by 2030. Accessing Yamal is of principal significance for securing gas production growth.

A new gas production region is being shaped in Yamal to replace the traditional fields of the Nadym-Pur-Taz region. The increasing gas consumption in Russia and abroad will be satisfied mainly by Yamal gas in the nearest decades.

32 fields were discovered in the Yamal Peninsula and its offshore areas with the aggregate reserves (A + B + C1 + C2) and resources (C3) reaching 26.5 trillion cubic meters of gas and some 1.64 billion tons of oil and condensate. The Bovanenkovo field is the most significant one in Yamal as its (A + B + C1 + C2) gas reserves amount to 4.9 trillion cubic meters.

Bovanenkovo field

The Cenomanian-Aptian deposits of the Bovanenkovo field are a paramount development target in Yamal.

In October 2006 Gazprom decided to move on to the investment stage of the project.

The first startup complex, which comprises a comprehensive gas treatment unit (CGTU) with the annual gas capacity of 30 billion cubic meters and 60 wells, was commissioned on October 23, 2012.

The field productivity will gradually increase in proportion to the number of commissioned wells, CGTUs and booster compressor stations. In 2017 the field is planned to reach its design capacity of 115 billion cubic meters of gas annually, corresponding to approximately one-sixth part (17 per cent) of gas produced in Russia in 2011. In future, the design capacity of the field may be increased to 140 billion cubic meters of gas annually.

A total of three gas fields will operate within Bovanenkovo, comprising 4 CGTUs, 12 booster compressor stations and 775 wells. The field development will be carried out by more than 200 process, infrastructure and ancillary facilities, while the number of staff members will exceed 1,800 (about 3,000 including service companies).

Gas pipelines

Gazprom is constructing the Bovanenkovo – Ukhta gas trunkline system (GTS) to deliver Yamal gas to the Unified Gas Supply System (UGSS).

The first line stretching more than 1,240 kilometers (with account of standby lines of submerged crossings) and the first workshop of the Baidaratskaya compressor station have been constructed so far. The second line and eight compressor stations are currently under construction. It is planned to finish the GTS construction in 2016.

Railroad and airport

With a view to ensure deliveries of materials and equipment to the Bovanenkovo fields facilities, the Obskaya – Bovanenkovo railroad was built. In February 2011 regular operation of the railroad to the terminal point – the Karskaya station – was launched. The railroad length from the Obskaya station to the Karskaya station is 572 kilometers (525 kilometers to the Bovanenkovo station).

Moreover, the airport, which is able to accommodate both helicopters and airplanes, was built in the field.

Innovations at work

Coping with difficult environmental conditions of Yamal, Gazprom made the Peninsula a launching ground for high-performance, secure, innovative technologies and engineering solutions. Many of them had been specially developed on Gazprom's order for Yamal by the leading Russian research institutes and national companies.

Particularly, Russia's first integrated production infrastructure for gas extraction from the Cenomanian (520–700 meters deep) and Apt-Albian (1,200–2,000 meters deep) deposits, has been used in the Bovanenkovo field. This approach provides significant saving of infrastructure development costs and increases production efficiency. Producing wells drilling is carried out by the Ekaterina drilling rigs of the fifth generation, manufactured in Russia and manifesting the best engineering ideas.

Gas treatment is carried out applying the most advanced and environmentally clean method of low-temperature separation with the use of domestic turbo expanders.

For gas transmission via the Bovanenkovo – Ukhta GTS the onshore gas pipelines are operated at the working pressure of 11.8 MPa (120 Atm) for the first time ever. It enables to reduce the amount of lines and metal consumption. The unique domestic 1,420 millimeter pipes made of K65 (X80) steel and with a smooth interior coating are used in construction.

In order for the Obskaya – Bovanenkovo railroad to cross the floodplain of the Yuribey River, the world's longest and unparalleled bridge 3.9 kilometers long was built beyond the Polar Circle.

Environmental care

In the construction process Gazprom's primary concern is preserving the unique nature of Yamal. Thus, process facilities occupy the least possible area.

Technologies reducing the impact on the permafrost are applied, such as vapor-liquid heat stabilizers and insulated pipes for wells. In-plant recycling systems eliminating water and soil pollution are used. There are special crossings of utility lines for free migration of deer. Constant environmental monitoring is carried out.

Cooperation

The Yamal-Nenets Autonomous Area has been a strategic region for Gazprom for several decades, and with the start of gas production in Yamal the role of the region in energy supplies to Russia will become ever more important.

Over six years, between 2007 and 2012, Gazprom's capital investments (including subsidiary companies) in regional projects totaled some RUB 1.6 trillion, including investments into the Bovanenkovo field development, construction of the Bovanenkovo – Ukhta GTS and the Obskaya – Bovanenkovo railroad, the Zapolyarnoye, Urengoyskoye, Yamburgskoye fields pre-development, the Urengoy gas transmission hub expansion and the Zapolyarnoye – Urengoy gas pipeline construction.

Gazprom's large-scale activity in the Yamal-Nenets Autonomous Area yields considerable profits to the regional budget. The volume of the Company's tax payments is growing year by year. Thus, Gazprom paid around RUB 45 billion in taxes to the regional budget in 2011, and around RUB 40 billion for 9 months of the current year so far. Eventually, after bringing the Bovanenkovo field to its full capacity, Gazprom's tax payments to the Yamal-Nenets Autonomous Area budget may exceed RUB 70 billion.

The principal document regulating cooperation between Gazprom and the Yamal-Nenets Autonomous Area is the General Agreement. In furtherance of the document the parties annually enter into Agreements of Cooperation. They have also signed a Memorandum of Cooperation, accords on gasification and cooperation in the natural resources exploitation area.
