Horse Hill-1 Test Hits Landmark 50,000 Barrels of Oil Production

UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce that, as at close of business on Friday 7(th) June, total aggregate Portland and Kimmeridge test oil production from the Horse Hill oil field, in which the Company has a 50.635% majority interest, reached a significant landmark of 50,000 barrels ("bbl") of light, sweet, dry oil. Total aggregate test production now stands at 50,871 bbl.

Horse Hill-1 continues to produce Portland oil at a stable rate of over 220 barrels of oil per day ("bopd") via a modest pressure draw down. The Portland has now delivered an aggregate total of 25,777 bbl to date, exceeding the 25,094 bbl produced from the deeper Kimmeridge. During the test, no formation water has been produced from either the Portland or Kimmeridge reservoirs.

Portland test production is now planned to continue until the second half of June when final site preparations for simultaneous HH-2/2z Portland drilling and HH-1 Kimmeridge production operations will commence. To facilitate both safe drilling and coring of HH-2/2z through the Portland, to provide continued oil sales revenues and further valuable test data prior to drilling HH-1z, preparations will include switching test production to the deeper Kimmeridge oil pool. Further necessary logistic and administrative arrangements for the arrival of the drilling rig and associated services are scheduled to be finalised this week.

The Horse Hill oil field and surrounding highly prospective PEDL137 and PEDL246 licences are operated by UKOG's subsidiary company Horse Hill Developments Ltd, in which UKOG holds a 77.9% direct interest.

Horse Hill 2018-19 EWT Oil Production Milestones:

   --    50,871 bbl aggregate Kimmeridge and Portland oil production 
   --    25,777 bbl total Portland production 
   --    25,094 bbl total Kimmeridge oil production 
   --    No discernible formation water produced from either reservoir 
   --    Stable Portland test production continues to prove more oil in the ground 

Stephen Sanderson, UKOG's Chief Executive, commented:

"The Horse Hill Portland continues to produce strongly and consistently under modest pressure draw downs, delivering over half of the landmark 50,871 bbl test production to date. With the much awaited simultaneous HH-2/2z Portland horizontal drilling and HH-1 Kimmeridge test campaign fast approaching, the remainder of the year at Horse Hill now promises to be truly exciting and potentially transformational for both Horse Hill and UKOG."

Glossary

 
 draw down             pressure drawdown ( P) is defined as the difference 
                        between the reservoir pressure and the flowing 
                        bottom hole pressure. Drawdown enables fluids to 
                        flow from the reservoir into the wellbore. The 
                        magnitude of the drawdown is a major controlling 
                        factors of a well's production rate 
 extended well         a well test, as per the permission granted by the 
  test or production    Oil and Gas Authority, with an aggregate flow period 
  test                  duration over each zone of greater than 96 hours; 
                        the objective being to establish whether a discovery 
                        is commercially viable and the optimal methods 
                        of future production and recovery 
                      ------------------------------------------------------- 
 flow test             a flow test or well test involves testing a well 
                        by flowing hydrocarbons to surface, typically through 
                        a test separator; 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 
                      ------------------------------------------------------- 
 oil field             an accumulation, pool or group of pools of oil 
                        in the subsurface that produces oil to surface
