Severneftegazprom Taking the next step
The Yuzhno-Russkoye field has constantly supplied an annual volume of around 25 billion cubic metres of natural gas. To keep production at this level, the joint venture is developing the next layer of the challenging reservoir.
Together with Gazprom and OMV, Wintershall Dea operates the Severneftegazprom joint venture, which produces 25 billion cubic metres of natural gas per year for Western Europe from the Yuzhno-Russkoye field. The field is located about 3,500 kilometres north-east of Moscow in the Yamal-Nenets Autonomous Area in Western Siberia and is one of the largest in Wintershall Dea‘s portfolio in terms of production.
Four challenging rock strata
The Yuzhno-Russkoye field consists of four rock strata containing natural gas and oil: Cenomanian, Turonian, Lower Cretaceous and Jurassic. Natural gas has been produced from the Cenomanian deposits since 2007. Booster systems are used to counteract the natural drop in pressure and decline in production.
Taking on the next rock strata
The technical challenges of developing the deeper geological formations in the Yuzhno-Russkoye field are enormous. In order to extend the plateau production from the field, Severneftegazprom is developing the Turonian formations, for which little practical experience has been gained to date. Severneftegazprom started operating the first test wells in the Turonian formations in 2011. Over 120 new wells will be drilled between 2020 and 2033 as part of the production start-up from the Turonian formations. The first Turonian well clusters of the full field development came on stream in 2020 and the acceleration of the development is ongoing. Until December 2021, Severneftegazprom produced 10 billion cubic metres of Turonian gas.
Furthermore, the Lower Cretaceous deposits were tested with six appraisal wells during 2015-2017 and further appraisal works will follow under a separate appraisal project. In the Jurassic layers two appraisal wells are committed to be drilled.
At Severneftegazprom we work according to the highest standards: we use the latest technologies, have good equipment, qualified personnel and a budget that allows us to carry out our demanding projects. It couldn't be better.
Implementing cutting-edge technological solutions
Harnessing the potential of digitisation in gas production, Severneftegazprom is currently developing the “Digital Twin of the Geological-Technological Model” project aimed at more effective and efficient development of the Cenomanian and Turonian formations. By reducing operating costs and increasing reliability and production efficiency, it will take already successful performance of Severneftegazprom to the next level.
