Achim Development has commenced the hot commissioning of Area 5A of the Urengoyskoye oil, gas and condensate field in Siberia.
Following the production of first gas from the Achimov formations in Area 4A, the two production complexes are currently undergoing testing procedures under operating conditions.
The commencement of this process represents a milestone for Wintershall Dea and Gazprom in the development of the Achimov deposits.
Achim Development is the joint venture of Wintershall Dea, which holds a 25.01% stake and Gazprom with 74.99% interest.
The firm began the work of simultaneous preparation of Areas 4A and 5A in 2018 for production start-up to develop gas and gas condensate reserves of the Achimov formations in the Urengoyskoye field.
In addition to the harsh climatic conditions and sensitive environment of the Siberian tundra, Achimov formations lie at depths of up to 4,000m in a region with complex geology, posing additional challenges for drilling operations.
The hot commissioning of the start-up complex was launched in January.
In the first phase of developing the required infrastructure and facilities, Achim Development got support from Achimgaz, a 50:50 joint venture between Wintershall Dea and Gazprom Dobycha Urengoy.
Achimgaz has been operating Area 1A of the Urengoyskoye field since 2008.
Although this process is ongoing, Achim Development has commenced complete field development of Area 4A/5A.
Wintershall Dea board member Thilo Wieland said: “Russia is a very important core region for our company, and our projects in Russia are a central pillar in achieving our company’s strategic goals. The start of hot commissioning of both Area 4A and Area 5A is an impressive achievement and another great success in our long-standing partnership with Gazprom.
“I am delighted that together with our other joint ventures in Western Siberia, Severneftegazprom and Achimgaz, Achim Development will significantly contribute to our production for many years to come.”
Following the completion of hot commissioning, Achim Development will now work on ramping up its production volumes towards complete project capacity.
This will lead to a huge increase in Wintershall Dea’s production in Russia.
The total annual planned production capacity of Area 4A/5A is 14 billion cubic metres of dry gas.
