HORSE HILL DEVELOPMENTS LTD

Horse Hill Developments (“HHDL”) was formed to drill, appraise and develop any hydrocarbons found at the Horse Hill wellsite, located in licence PEDL137 in the Weald Basin, 3km north of Gatwick Airport. HHDL originally drilled the Horse Hill-1 (HH-1) oil discovery well in 2014 and followed with flow testing in February and March 2016. HH-1 tested at a commercial aggregate stable dry oil rate of 1,688 barrels of oil per day from the Portland and two Kimmeridge Limestone reservoir horizons. In September 2019, Surrey County Council granted Horse Hill Development Ltd (HHDL) planning permission for four more oil wells, plus one wastewater reinjection well, and 20 years of full oil production. The field and surrounding licence is operated by UKOG's subsidiary company Horse Hill Developments Ltd (“HHDL”) in which UKOG has 77.9% ownership.
