RE: Horse hill ... ongoing plans.... for Kim and Portland3 May 2021 11:59
spot the differences;
11.9.19 RNS from UKOG
"The planning consent gives permission to produce oil over a period of 25 years at up to 3,500 barrels of oil per day from a total of six wells within the Portland and Kimmeridge oil pools, including the existing Horse Hill-1 ("HH-1") and the forthcoming HH-2/2z horizontal well. Consent also includes permission to drill one water reinjection well to help maximise oil recovery. All existing and future wells will be drilled from within the existing 20 x 15 metre concrete pad. No further drilling sites beyond Horse Hill are required."
Compare that to the 1st April 2021 SUBMISSION OF AMENDED PLAN & FORM , page 12
"The proposed activities to be undertaken at the well site are the extraction, storage and export of crude oil. The Applicant proposes the construction of a process and storage area and tanker loading facility to enable the production of hydrocarbons from two (2) wells for a period of twenty (20) years inclusive of well maintenance workovers and sidetrack drilling operations. The activities will consist of the extraction of petroleum from the well formation via the wellbores (HH-1 and HH-2z) to surface where it is processed through a three (3) phase separator."
Only two wells mentioned and I note reduced length of production life in years.
This is what UKOG say is "likely technical recoverable"
"For guidance purposes only, the Company's qualified persons ("QP") consider that the 1C value of 0.6 mmbbl carried for Horse Hill in Table 3, below, provides a reasonably representative view of HH-1's likely technical recoverable Portland reserves at the end of 2020. "
(from annual results RNS)
If only we could view the in house depletion curve that caused the huge write down in HH value.
Think 20 years to end of HH commercial production and 600,000 barrels. The simple mathematics do not suggest a high daily production for any significant length of time.
Pity UKOG do not publish their own self generated depletion curve.
