UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce that following this morning’s arrival of a small workover rig, planned routine intervention operations at its 85.635% owned Horse Hill-1 well have now commenced.

The short intervention seeks to further optimise oil flow via reperforating the full Portland oil producing section, insertion of a new simplified production tubing string and by setting the downhole pump at a deeper level to increase pumping efficiency.

**Further updates will be issued in due course following completion of the intervention.**

The Horse Hill Portland and Kimmeridge oil field is operated by UKOG’s subsidiary company Horse Hill Developments Ltd (“HHDL”), in which UKOG has a direct 77.9% interest. HHDL has a 65% interest in the field and surrounding PEDL137 and PEDL246 licences, with the remaining 35% interest held by UKOG’s wholly owned subsidiary, UKOG (137/246) Ltd.

**Qualified Person’s Statement**

Matt Cartwright, UKOG’s Commercial Director, who has 37 years of relevant experience in the global oil industry, has approved the information contained in this announcement. Mr Cartwright is a Chartered Engineer and member of the Society of Petroleum Engineers.

**Stephen Sanderson UKOG’s Chief Executive commented:**

“We look forward to safe, swift and successful operations and to the resumption of stable oil production at Horse Hill as soon as possible.”
