PEDL137 Horse Hill Oil Field (UKOG 46.735%)
· The Company's primary 2019 operational goal will be to deliver continuous oil production from Horse Hill via continued extended well testing ("EWT") of Horse Hill-1 ("HH-1") and by the drilling and production testing of two horizontal wells, HH-1z and HH-2, both planned to start in spring 2019. Planning consent and environmental permits are in place and UKOG is fully funded for both wells.
· The first new horizontal well, HH-2, will target the Portland oil field, while the second, HH-1z, a horizontal sidetrack of HH-1, will target the combined 358 ft thick Kimmeridge Limestone 3 ("KL3") and KL4 oil pool, currently on sustained test production from the HH-1 wellbore.
· Utilising the reported flow rates from the current HH-1 vertical wellbore's EWT campaign, both HH-1z and HH-2 each have targets of initial sustained daily horizontal well rates of 720-1,080 bopd. These targets are deemed by the Company's 3rd party reserve auditor and principal reservoir engineering advisor, Xodus, to be viable and realistic, conforming with the established petroleum engineering benchmark that an optimally placed horizontal well within a reservoir with reasonable vertical permeability can be expected to deliver 2 to 3 times the flow rate of a vertical wellbore from the same reservoir.
· Further horizontal production wells and a water reinjection well are planned to be drilled in early 2020 following the grant of regulatory approvals for permanent oil production, applications for which have been submitted. Permits to cover 20 years of production are expected to be in place by autumn 2019.
