UK Oil & Gas declares Horse Hill’s Portland reservoir “commercially viable”
A development of the Portland would comprise up to three production wells and two pressure support wells
It is envisaged that long-term production operations could begin during 2019. The development – of the Portland and Kimmeridge zones - will require additional planning permission. UKOG said the application is nearing completion, and, submission is anticipated before the end of 2018.
UKOG holds an indirect 46.735% beneficial interest in Horse Hill, via its shareholding in the HHDL vehicle which in turn owns 65% of the asset.
"HHDL's declaration of Portland commercial viability is a significant milestone for the Company,” said UKOG chief executive Stephen Sanderson.
“It transforms Horse Hill from solely exploration into a fully-fledged field development with a full-scale oil production start-up targeted in 2019.”
He added: “The better than expected EWT results have robustly demonstrated that the Portland has significant daily production potential in its own right, which could see the first planned horizontal producer attain sustained oil rates of 720-1,080 bopd.
“If realised, these rates could make the Horse Hill Portland oil field one of the UK onshore's top producers.”
Kimmeridge testing continues
Sanderson also highlighted that the Portland conventional oil field project could be combined with the development of the deeper, unconventional Kimmeridge zones – which are presently on the extended test.
Latest results, released earlier this week, exceeded those seen in the previous tests back in 2016.
The first Kimmeridge test has seen oil flow continuously and naturally from the KL3 zone to surface.
Test flows measured production rates between 563 and 771 barrels of oil per day, before further testing programme resumed with pressure build up, clean-up, flow stabilization, oil sampling.
After that, the programme moves on to test production from the KL4 zone where, in 2016, a rate equivalent to 901 bopd was measured over a four hour period.
