Wintershall produces first gas from Sillimanite South field

Wintershall Noordzee BV, a 50-50 joint venture of Wintershall Dea GmbH and Gazprom EP International BV, has started production of the D12-B3 well, the Sillimanite South field discovery well.

 

The gas field was discovered in 2020 following completion of the second Sillimanite development well which was taken into production in June 2020.

 

D12-B3 is the third new well which Wintershall Noordzee has taken into production in the past 12 months.

 

After hook-up activities of the Sillimanite South production well to the D12-B production satellite platform had successfully been completed, first gas was introduced. The D12-B satellite platform is situated close to the Anglo-Dutch border in Dutch territorial waters. From there, the produced gas will be transported via the Neptune Energy-operated D15-A production platform, through the NGT (Noordgastransport) gas transportation system to shore.

 

The unitised Sillimanite gas field stretches across the UK and the Dutch Continental Shelves in licence Block 44/19a on the UK side and Blocks D12a and D12b on the Dutch side.

 

A treaty between the UK and Dutch governments entered into force in July 2018.

 

Sillimanite South field is located entirely in Block D12a.

 

Both Sillimanite and Sillimanite South gas fields are producing from sandstone reservoirs of Carboniferous age at a depth of 3,700 metres subsea.

 

Sillimanite South joint venture partners are: Wintershall Noordzee BV (operator, 39.5%), EBN BV (50%) and Neptune Energy (10.5%).
