Reduced Decommissioning Liability

In accordance with the Company's policy of maintaining a minimal well stock sufficient only to fulfil its production aims, Angus Energy plc (AIM : ANGS) is pleased to announce a further review of its abandonment liabilities at the Saltfleetby Gas Field.

Specifically the Company has obtained firm quotation for the abandonment of Wells 6 and 7 for an aggregate total of £335,000 ex VAT. Together with the £70,000 of costs of abandoning Wells 1 and 3, already successfully completed, the total cost of decommissioning four of the field's eight wells will be less than £405,000 as against an original gross estimate of £1.75 million for decommissioning all eight wells (excluding £0.75m of site restoration costs) of which Angus share is 51%.

SF01 & SF03: Fully Abandoned - cost c. £70,000

SF06 &SF07: Cost for Abandonment - c. £335,000

SF02 & SF04: Ready for immediate resumption of production

SF05: Target well for side-track in 2021

SF08: Near-term producer completed to the reservoir with pressure to surface

Also potential longer term candidate for storage/geothermal

We will proceed immediately to submit an abandonment programme for well SF06 to the relevant authorities. The Company will follow with a programme for SF07 as soon as it is clear that SF05 is a workable proposition for sidetracking in 2021. If SF05 is not, then the Company would use SF07 as the side-track well and abandon SF05 in its place.

George Lucan, Managing Director, comments "On the basis of third party quotations to date, our estimates for overall decommissioning liability appear to have been very conservative. We will complete a full review and costing of the remaining four wells but at present it seems likely that overall decommissioning liability will be substantially smaller than originally anticipated.

Angus' exposure for this decommissioning liability is only 51% following first gas. This accelerated programme would therefore expose Angus to 100% of the cost but we have now agreed in principle cost recovery from future revenues of all partners in the Field."
