HH-1 is located in licence PEDL137 in which UKOG holds a 46.735% beneficial interest. Key EWT results to date are summarised below:\n \nKey Points:\n \n· KL3 EWT flow sequence commenced ahead of planned KL4 test. \n· KL3 flowed 40-41° API continuously and naturally to surface (i.e. without any pump) over a 50 hour initial planned oil flow period. Oil flow initiated instantaneously with minimal pressure \"draw-down\". First planned 24-hour shut-in and pressure build-up test (\"PBU\") now underway.\n· Sustained continuous oil rates of between 563 and 771 barrels of oil per day (\"bopd\") on 36/64 and 38/64 inch choke, respectively, recorded over last 24 hours through test separator. Gas rates up to 186,000 cu ft per day measured through enclosed flare. Flow sustained at constant stable bottom hole pressure.\n· Recorded sustained rates significantly exceed the 464 bopd over a short 7.5-hour total flow period reported in 2016. \n· Initial well productivity index of between 1.4 to 2.5 bpd/psi is around twice that seen in 2016 KL3 test.\n· To date four tankers of KL3 crude have been exported to Fawley refinery.\n· Zero formation water produced. Metered associated water rates of 52 barrels per day (\"bpd\") decreasing to 14 bpd (i.e. 9% decreasing to 2%) in the past 24 hours. Produced water consists wholly of retur...
