On 6 March 2018 Baron Oil Plc announced that it has entered into a deal with Corallian Energy Limited in which Baron will take a 5% interest in licence P1918 which contains the Colter discovery. Under the terms of the deal Baron will pay 6.67% of the well costs, capped at GBP 8 million, costs above this cap will be funded at 5%. Along with 5% share of back costs unrelated to the well the total amount payable by the company is GBP 425,000. The deal is subject to regulatory approval.  The Colter discovery was made by BP in 1986 where 41.9Â° API was recovered on test from a 10.5 m oil column. Through the merging and reprocessing of 3D seismic Corallian has mapped 100 m of vertical relief up-dip of 98/11-2. Licence P1918 was initially awarded to Infrastrata from the 26th Seaward Licensing Round prior to Corallian taking the acreage. The company reprocessed 156 km of 2D seismic and 33.5 sq km of 3D seismic over the licence. It is thought that Colter could hold mean prospective resources of 26.8 MMb (recoverable). The plan is to appraise the discovery in 2018 with a Jack-Up rig drilling a well to a TD of 1,800 m and if successful the field could be developed via the Wytch Farm facilities.  Interest in the licences following completion of the deal will be held by Corallian Energy Limited (45% + operator), Corfe Energy Limited (40%), United Oil and Gas Plc (10%) and Baron Oil Plc (5%).
