The UKOG news release of 15 April 2015 in full is as follows:

Further to its announcement of 9 April 2015 in relation to the upgrade of its Horse Hill discovery, London quoted UK Oil & Gas Investments PLC (LSE AIM: UKOG) wishes to repeat and clarify a number of points as a result of recent reports in the media.

US-based Nutech Ltd ("Nutech") estimates that the Horse Hill-1 ("HH-1") well in the Weald Basin has a total oil in place ("OIP") of 158 million barrels ("MMBO") per square mile. The upgrade is in relation to the Kimmeridge, Oxford and Lias sections of Horse Hill and does not relate to the previously reported Upper Portland Sandstone oil discovery.

The OIP hydrocarbon volumes estimated should not be considered as either contingent or prospective resources or reserves.

The Horse Hill licences cover 55 square miles of the Weald Basin in southern England in which the Company has a 20.358% interest. It is estimated that the relevant Jurassic section of the Weald Basin is approximately 1,100 square miles. The Company has not undertaken work outside of its licence areas sufficient to comment on the possible OIP in either the approximate 1,100 square miles or the whole of the Weald Basin.

Further development work in the form of appraisal drilling, well testing and assessment of recovery factors will be required to seek to quantify net resources in relation to the Company's licence areas and to prove its commerciality.

Nutech's report to the Company states this OIP of HH-1 lies within a 653 feet aggregate net pay section, primarily within three argillaceous limestones and interbedded mudstones of the Kimmeridge, and the mudstones of the Oxford and Lias sections. Approximately 72% of OIP, or 114 MMBO, lies within the Upper Jurassic Kimmeridge interbedded limestone and mudstone sequence.

In order to establish estimates of total OIP within the licence areas, the semi-regional resource potential of the Weald Basin's eastern footprint is the subject of ongoing analysis under the contracted alliance between Nutech, UKOG and Solo Oil Plc. The results of the estimated OIP within the licence will be reported when completed.

Final assessments of the Upper Portland Sandstone and the Oxford and Lias sections are in progress, with further results expected shortly.

The executive summary of the Nutech report is available on the Company's website at www.ukogplc.com.

UKOG's interest in Horse Hill:

The Horse Hill-1 well is located within onshore exploration License PEDL137, on the northern side of the Weald Basin near Gatwick Airport. UKOG owns a 30% direct interest in Horse Hill Developments Ltd ("HHDL") and a 1.32% interest in HHDL via its 6% interest in Angus Energy Limited. HHDL is a special purpose company that owns a 65% participating interest and operatorship of Licence PEDL137 and the adjacent Licence PEDL246 in the UK Weald Basin.
