Portland Oil Production Resumes at Horse Hill Oil Field

 

UK Oil & Gas PLC (London AIM: UKOG), is pleased to announce that its subsidiary company, Horse Hill Developments Ltd has re-established Portland oil production from the Horse Hill-1 ("HH-1") well in which the Company has a 50.635% majority interest. The resumption of continuous Portland dry oil flow (i.e. oil with zero water content), at a stable daily rate of between 208 to 218 barrels per day ("bopd"), forms a key part of the schedule of works required to finalise the Portland field development plan and to the targeted establishment of permanent long-term Portland production, planned by end 2019.

 

Further details of extended well test ("EWT") results to date are summarised below.

 

Horse Hill 2018-19 EWT Oil Production Milestones:

 

·     Over 30,200 barrels ("bbl") aggregate Kimmeridge and Portland oil production to date.

·    Over 25,000 bbl total Kimmeridge oil production.

·     Over 5,100 bbl total Portland production to date, flow continues.

·     142 tankers of crude successfully exported primarily to Perenco's Hamble oil terminal. The KL's 40° API Brent quality crude containing no produced water, continues to be sold at prevailing Brent crude oil prices, less a small deduction for handling and marketing.

 

Portland Test Production and Future Plans

 

For prudent reservoir management purposes, the average test production rate from the 114 ft vertical perforated Portland section has been maintained below the previously reported 362 bopd calculated optimised sustainable rate. HH-1 test production is planned to continue until the completion of the new HH-2 Portland horizontal well, scheduled to start in spring 2019, and for which planning and environmental permits are in place. Portland test production will then be switched over to HH-2.

 

As detailed in UKOG's 23 January 2019 Strategic Review, the HH-2 Portland flow rate target of 720-1,080 bopd from the HH-2 horizontal well, which has been externally verified as a realistic and viable expectation by Xodus Group Ltd ("Xodus"), is designed to position Horse Hill as the Weald Basin's leading oil producing field by year end. Subsequent planned horizontal wells in 2020 are designed to further boost gross Portland production and to position UKOG as one of the current top three oil producing companies in the UK onshore sector.

 

Kimmeridge Future Test Production Plans

 

In tandem with Portland operations, the Kimmeridge oil pool was shut-in to conduct a further long-term pressure build up test.  Pressure gauges, set within the Kimmeridge reservoir, will monitor the Kimmeridge reservoir whilst the Portland is flowed.

 

Resumption of continuous Kimmeridge test production is now planned to follow directly after the drilling of HH-2. Initially via a short flow test period from HH-1, then by further long term production testing of the new HH-1z Kimmeridge sidetrack, for which planning and environmental consent are in place. As the HH-1z Kimmeridge horizontal has similar flow rate targets as the Portland, there is significant potential to increase aggregate production towards the 3,500 bopd envisaged maximum detailed in the recent planning application.

 

Stephen Sanderson, UKOG's Chief Executive, commented:

 

" After a 6-month shut in period, the continued good flow performance from the Portland further reinforces the viability of Xodus' and the Company's 720-1,080 bopd horizontal well production targets. We remain on course to commence the first two horizontals in Spring, with long term production testing of both wells planned to follow directly afterwards. The flow test results to date, combined with the prospect of further near term drilling, place Horse Hill in a strong position to deliver positive "free" cash flow to UKOG in the near and foreseeable future."

Glossary

 

°API	a measure of the density of crude oil, as defined by the American Petroleum Institute
oil field	an accumulation, pool or group of pools of oil in the subsurface that produces oil to surface.
extended well test (EWT) or production test	a well test, as per the permission granted by the Oil and Gas Authority, with an aggregate flow period duration over all zones of greater than 96 hours and generally up to 90 days maximum flowing time per productive horizon. The objective being to establish whether a discovery is commercially viable and the best 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.
horizontal well	a well that during drilling is steered so as to follow and remain within a particular geological stratum or reservoir unit having a trajectory that runs  approximately parallel to the top and or base of the target horizon
positive "free" cash flow	Revenues that have paid back the full capital cost of the activity, in this case the cost of the well. If the prognosed target rates are met, and at current oil prices, the planned horizontal wells are expected to pay-back capital costs in under 6 months.
sidetrack	re-entry of a well from the well's surface location with drilling equipment for deviating from the existing well bore to achieve production or well data from an alternative zone or bottom hole location
