The Sillimanite field was discovered by exploration well 44/19-8 drilled in 2015 which tested at good flow rates from Carboniferous sands.

A joint exploration

The field straddles the UK/NL border and a tax treaty is in preparation, while the joint venture is in the process of selecting the development scheme. Infrastructure is nearby and first gas is planned for 2020.
ONE holds a 7.9% unitized interest in the field originating from licence interests in both UK block 44/19a as NL block D12b.
