UKOG was founded in December 2013, via a reverse listing on the UK Alternative Investment Market and the renaming of its predecessor company, Sarantel Group Plc. The Company took the strategic decision to specifically focus on a portfolio of investments in UK oil and gas assets.

UKOG’s first investment, also in December 2013, was to acquire a 7.5% ownership interest in Horse Hill Developments Ltd (HHDL), which owns 65% of the two Horse Hill licences, located about 3 miles from Gatwick Airport.  Subsequently, UKOG further increased its interest in HHDL to 30%, making UKOG the largest HHDL shareholder today.

In February 2014, the Company acquired a 6% ownership interest in Angus Energy Limited (Angus), which operates and produces low cost oil from both the Lidsey and Brockham oil fields in the UK Weald Basin south of London. Like UKOG, Angus is an owner of HHDL.

A further key transaction by UKOG was the acquisition in July 2014 of the UK subsidiary companies and UK assets of Northern Petroleum (NOP):

  • Three NOP companies were acquired and renamed UKOG (GB) Limited, UKOG Weald Limited and UKOG Solent Limited
  • The acquisition was completed in October 2014
  • Five UK licences were acquired, four onshore and one offshore, all located in the South of England
  • The assets acquired include the Horndean and Avington onshore producing oil fields, an offshore Isle of Wight exploration licence and the Baxters Copse and Markwells Wood onshore oil discoveries
  • In October 2014, UKOG jointly applied for a 200 square km onshore licence, adjacent to the offshore Isle of Wight licence, including an exploration well, as part of the UK’s 14th Landward Licence Round (14th Round)

HHDL’s milestones in 2014 included:

  • September - November 2014: Drilling operations at the Horse Hill-1 exploration well (HH-1)
  • Announcement of conventional Upper Portland Sandstone oil discovery at HH-1
  • December 2014: Update on HH-1 discovery, including the recognition of the Upper Jurassic limestone oil potential.
