On 18 June 2018 BP acquired Premierâs 5% interest in P380 (block 43/26a Ravenspurn North Field Carboniferous Area) which contains part of the Ravenspurn North field. Â   Ravenspurn North was discovered in 1984 with well 43/26-1. The field is a large Permian gas (dry) field and was brought onstream in 1990. It is located adjacent to the Ravenspurn South accumulation which was discovered in 1976. On 2 December 2016, Perenco, on behalf of block operator BP, spudded well 43/26a-E12 targeting the Ravenspurn North Deep prospect. BP believed if successful, it could open a new phase of development in the region. The target was the Carboniferous beneath the depleted Rotliegend reservoir focussing on tight gas. The well was plugged and abandoned on 3 June 2017 and development sidetrack 43/26a-E12Z was kicked off and completed on 22 October 2017. BP states that the play warrants further exploration as the company is aware that the deeper carboniferous sands exist but what isnât clear is that if gas is encountered can long term production from the play be sustained.  Interest in the block is held by BP Exploration Operating Company Ltd (90% + operator) and Perenco UK Limited (10%).
BP acquired 5% stake in P380 block 43/26a Ravenspurn N Field Carboniferous area from Premier Oil.
