On 1 September 2018 Tailwind Energy completed the acquisition of Shellâs and ExxonMobilâs interest in the Triton Cluster in the Central North Sea. Under the deal Tailwind has acquired 29.26% in licence P361, 64.63% in the unitised Bittern licence, 100% interest in licences P1792 and P233 blocks (029/01a Bittern Area), P013 (021/25a Guillemot W / NW (Upper), 021/30a Guillemot W / NW (Upper), Gannet E and 50% interest in P215.  The Triton Cluster comprises of Guillemot NW, Guillemot W, Bittern and Gannet E. Bittern was developed jointly with Guillemot West and Guillemot Northwest as part of the Triton project. The Triton project was initially a subject of controversy as the respective operators of the two blocks it straddled failed to agree on a development scheme. A joint development scheme for the field was finally agreed on 5 November 1997. The solution involved the development of Bittern jointly with Guillemot West and Guillemot Northwest as a subsea development tied back to a new-built FPSO vessel, moored mid-way between the fields. Bittern came on stream on 15 April 2000 and production commenced from the Guillemot Northwest and Guillemot West fields on 20 April 2000. Gannet E is in the process of being redeveloped via a tie-back to three existing wells to the Gannet Alpha platform and then on to the Titron FPSO. Gannet E was shut in, in 2011, but is expected back onstream later in 2018.  Following the completion of this deal interest in P361 is held by Dana Petroleum (E&P) Ltd (65.90% + operator), Tailwind Energy Ltd (29.26%) and Endeavour North Sea Ltd (4.84%). In the Bittern unitised licence the interest is held by Dana Petroleum (E&P) Ltd (32.95% + operator), Tailwind Energy Ltd (64.63%) and Endeavour North Sea Ltd (2.42%). In Licences P1792 + P233 (029/01a Bittern Area), P013 (021/25a Guillemot W / NW (Upper) + 021/30a Guillemot W / NW (Upper) + Gannet E, TailwindÂ holds 100% interest. Lastly in P215 interest in the licence is now held byÂ Dana Petroleum (E&P) Ltd (50% + operator), Tailwind Energy Ltd (50%).
Tailwind Energy has agreed to acquire the entire UK business of EOG Resources, which include 100% in the Conwy field and 110/12a-1 Corfe discovery in the East Irish Sea, a 25% interest in the Columbus gas development and also interest in number of Southern North Sea licences.
