Yuzhno Russkoye 600 billion cubic meters of natural gas reserves

The Yuzhno Russkoye field, which has recoverable reserves of more than 600 billion cubic meters, is situated around 3,500 kilometers northeast of Moscow in the autonomous district of Yamal-Nenets. The Russian gas field was officially commissioned by Gazprom and Wintershall at the end of 2007, making Wintershall the first German company to directly produce natural gas in Western Siberia. Wintershall has a 35 percent share in the commercial success of the field through its participation in the operating company Severneftegazprom. Together with Gazprom, the German company Uniper is another partner that is involved in developing the Yuzhno Russkoye field.

The Yuzhno Russkoye gas field was discovered back in 1969. The entire concession covers 722 square kilometers. The gas is now produced mainly from the Cenomanian formation, which lies at a depth of around one kilometer. The natural gas has a very high degree of purity, with a methane content of 98 percent.

Production 25 million cubic meters of gas per year

A genuine milestone was the first trial production well of the joint venture Severneftegazprom in December 2011, which was used to recover natural gas from the Turonian formation at a depth of 810-840 meters.

Two Turonian wells are currently in trial operation, from which a total of 320 million cubic meters of natural gas have already been recovered. At the same time, plans for the extensive production from this formation are being developed. The production tests for the Turon formation are expected to be completed by 2018.

To date, more than 140 production wells (including two Turonian test production wells) are currently in operation. The total daily production is about 70 million m³ of natural gas, subject to seasonal influences. The plateau production of 25 billion cubic meters of gas per year has therefore been reached.

exploration phase
1979 Start of the first
exploration phase
1969 Discovery of the
Yuzhno Russkoye reservoir

The reserves in the Yuzhno Russkoye gas field are exposed to low temperatures, which means that precautions have to be taken to prevent hydrate formation.

In addition, there are high reservoir pressures and the reservoir rock has low permeability. As a pioneer in this regard, Severneftegazprom is currently testing the development of the Turonian formation, where there has been very little practical experience in Russia until now.

The bundling of technological expertise and the expert know-how of the partners, including Wintershall, are decisive for the successful development and implementation of the project.

Key project figures Yuzhno Russkoye in facts and figures

In addition, sandstone formations in Lower Cretaceous and Jura strata in the Yuzhno Russkoye license area, which are up to 4,000 meters deep, have been undergoing testing since April 2014. In 2016, the sixth out of a total of eight planned exploratory wells was begun.

As part of the exploration activities being carried out by Severneftegazprom, roughly 200 meter-long drill cores shall be extracted from each well in order to gain additional information about possible natural gas, gas condensate and oil deposits.
