Horse Hill Field Granted Long-Term Production Consent by OGA

UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce that the Oil and Gas Authority has approved the Horse Hill Field Development Plan and consented to the start of long-term production ("Production") from the field.

This key consent will enable net recoverable reserves to be allocated to the Company, a pre-requisite for future potential debt-based funding. It will also permit the Company to enter into long-term field operations contracts which can help reduce operating costs below $19 per barrel, making the field more profitable even at current low oil prices.

Portland oil pool Production will commence via Horse Hill-1 ("HH-1"), with Kimmeridge Production planned to be added in late spring via a conversion of the well to a dual completion. Production from HH-2z is planned to follow upon completion of the current extended well testing campaign.

UKOG holds a controlling 85.635% interest in the Horse Hill oil field and surrounding highly prospective PEDL137 and PEDL246 licences, which are operated by UKOG's subsidiary company, Horse Hill Developments Ltd.

Stephen Sanderson, UKOG's Chief Executive, commented:

"This is an important regulatory milestone, granting governmental Production consent. The Company can now focus firmly upon maximising stable production, reducing operating costs and generating positive cash flow. The ability to book reserves also opens the way to potential debt funding, a positive step towards both creation and preservation of shareholder value."

Glossary

dual completion	a production well with two sets of steel production tubing and pumps which enables two separate oil pools to be produced simultaneously
oil field	an accumulation, pool or group of pools of oil in the subsurface that produces oil to surface
reserves	Those quantities of petroleum that, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable from a given date forward from known reservoirs and under defined economic conditions, operating methods, and government regulations.
well test	or flow test involves testing a well by flowing hydrocarbons to surface, typically through a test separator over a flowing period of up to 96 hours; key measured parameters are oil and gas flow rates, downhole pressure and surface pressure. The overall objective is to identify the well's capacity to produce hydrocarbons at a commercial flow rate and volumes. An extended well test or EWT is a well test with duration of over 96 hours and up to 90 or 180 flowing days aimed at assessing longer term production viability and the connected oil in place seen by the well.
