Sillimanite

The Sillimanite unit is a cross-border field extending towards the UK and Dutch sectors of the North Sea, 200 km northwest of the coast of the Netherlands near the city of Den Helder.

As a cross-border unit, Sillimanite is operated under an intergovernmental agreement between the UK and the Netherlands and a unitization agreement signed by a consortium of companies with respect to three license blocks. The consortium for the asset is composed of: WINZ, EBN, Gazprom International UK Ltd., Neptune, and ONE with WINZ as the operator.

Sillimanite was discovered back in 2015 and has been developed from February 2020 onward. Two production wells, D12-B1 and D12-B2, produce natural gas from Lower Ketch carboniferous deposits.

Produced gas is pipelined to the onshore transport system.
