UK Oil & Gas Investments PLC
("UKOG" or the "Company")
Drilling Update, Horse Hill-1, Weald Basin UK
UK Oil & Gas Investments PLC (AIM: UKOG) advises that the Horse Hill-1 well has intersected the Portland Sandstone over the weekend and has encountered oil shows identified by mud logging from 2,100 feet to 2,140 feet measured depth ("MD"). At 14:00 hours yesterday, the well was drilling ahead at 3,030 feet MD towards the other primary and secondary targets.
Sandstone drill cuttings recovered from the well have been analysed and are confirmed by the operator to have "a dull yellow fluorescence with a slow diffuse light blue cut with a trace of residual oil ring". This indicates the presence of oil within a porous and permeable rock matrix. Gas readings within the mud over the same interval were also elevated and recorded gases compositions consistent with the presence of oil.
The Horse Hill-1 well is located on the northern side of UK Weald Basin near Gatwick Airport and is planned to test a number of conventional oil and gas targets. The primary oil reservoir targets in this well lie in the Jurassic age Portland Sandstone and the Corallian Sandstone. There are also a number of secondary oil targets in the Jurassic formations, including the Great Oolite Limestone. The well is presently being drilled to the second of the primary targets in the Corallian Sandstone. 
Electric logs will be acquired on reaching the third casing point at approximately 5,900 feet MD before setting a 9 5/8-inch casing. The well will then be drilled with an 8 -inch hole will be drilled to 8,658 feet total depth ("TD") in order to test for Triassic aged formations which are expected to contain gas.
UKOG owns a 20% direct interest in Horse Hill Developments Ltd ("HHDL") and an additional 2.4% interest in HHDL by virtue of its 6% ownership in Angus Energy Limited ("Angus Energy"). Angus Energy owns 40% of HHDL. 
HHDL is a special purpose company that owns a 65% participating interest and operatorship of onshore licences PEDL137 and the adjacent licence PEDL 246 in the UK Weald Basin. The participants in the Horse Hill-1 well are HHDL with a 65% working interest and Magellan with a 35% interest.
David Lenigas, the Company's Chairman, commented:
"Progress on this conventional well has so far been encouraging and we are pleased to report that oil shows have been encountered in the Portland Sandstones. The well will need to be electronically logged at the next casing point to understand the significance of these oil shows in the Portland and we look forward to reporting further drilling updates as the well progresses."
