On 25 September 2017 UK Oil and Gas Investments (UKOG) announced that it has acquired a further 10% interest in PEDL 143 from Warwick Energy Exploration and Production Limited. Partner Europa, which is also operator of PEDL 143, is planning to drill an exploration well at a site named Holmwood in the licence. UKOG confirmed on 6 December 2017 that the deal has completed.  On 27 June 2016 Europa reported that it had received OGA approval for a two year extension up to 1 October 2018, to PEDL 143 to enable it to drill the Holmwood well. In August 2017 it was confirmed that the well will spud later in the year. The Jurassic carbonate and sandstone target, located in the Weald Basin, is thought to have potential pre-drill resources of 5.64 MMbo. PEDL 143 was awarded in 12th Landward Licensing Round and covers an area of approximately 91 sq km. The prospect is located close to the Brockham field. Brockham was discovered in 1987 with well Brockham-1 by BP. The field is now operated by Angus Energy. On 29 June 2015 Egdon announced that it had agreed to farm-down 20% of its interest to UK Oil and Gas Investments in return for the latter funding 40% of the well costs. Gross well costs are anticipated at GBP 3 million. Egdon also farmed out 12.5% of its interest in the licence to Angus Energy and 7.5% to Union Jack Oil and Gas. Following completion of the deal, interest in the licence will be held by Europa Oil & Gas Limited (20% + operator), UK Oil and Gas Investments Plc (40%), Egdon Resources U.K Limited (18.4%), Angus Energy Ltd (12.5%), Union Jack Oil and Gas Plc (7.5%) and Altwood Petroleum Limited (1.6%) Â
