Bonanza as drilling firm strikes oil at Gatwick
UK Oil & Gas Investments (UKOG) said drilling of the 55-square mile site at the Weald Basin had discovered 158 million barrels per square mile.
Chief executive Stephen Sanderson said the Horse Hill-1 well required appraisal and testing to prove its commercial viability but that it had “the potential for significant daily oil production”.

Mr Sanderson told the BBC: “We think we’ve found a very significant discovery here, probably the largest [onshore in the UK] in the last 30 years, and we think it has national significance.”
Similar wells in the US had seen “estimated recovery factors” of between 3% and 15% of the oil in place, he added.
He said: “Drilling the deepest well in the basin in 30 years, together with the ability to use concepts, techniques and technology unavailable in the 1980s, has provided new cutting-edge data and interpretations to comprehensively change the understanding of the area’s potential oil resources.”

Hide AdUKOG has an interest of just over a fifth in the Horse Hill site. Shares in the company initially more than quadrupled in value on the announcement.
UKOG has a 30% direct interest in operator Horse Hill Developments Ltd (HHDL) and a 1.32% interest via its holdings in another company, Angus Energy. HHDL owns a 65% interest in the licence for the well.
In a statement today, UKOG said that in order to establish estimates of total oil in place within the licence area, the “semi-regional resource potential of the Weald Basin’s eastern footprint is the subject of ongoing analysis”.
Mr Sanderson told the BBC: “Based on what we’ve found here, we’re looking at between 50 and 100 billion barrels of oil in place in the ground.

UKOG chairman David Lenigas tweeted: “The Weald Basin is 1,110 sq miles and this discovery is very significant for UK. Very significant.”
He told Sky News the discovery would mean “many thousands” of jobs.
It has previously been estimated that the Weald Basin holds 4.4 billion barrels.

It estimates that between 12 billion and 23 billion barrels are left.
