Severneftegazprom, a joint venture of Gazprom, Wintershall Dea, and OMV, concluded the Turonian drilling campaign that began in 2018.
The JV completed drilling the 100th well in the formation of Yuzhno-Russkoye field in Western Siberia and this year plans to complete the tie-in for all Turonian wells drilled so far.
Gas production from the formation is aimed at complementing production from the Cenomanian deposits and prolonging the plateau production from the field.
Severneftegazprom—the only company in Russia to develop the Turonian deposits on a commercial scale—has so far produced 10 billion cu m of Turonian gas, most of it in 2021.
Wintershall operates the Severneftegazprom JV, which produces 25 billion cu m/year of natural gas for Western Europe from the Yuzhno-Russkoye field. The field lies about 3,500 km northeast of Moscow in the Yamal-Nenets Autonomous Area.
The 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.
