Orcadian Energy plc

("Orcadian" or the "Company")

Completion of sale of 50% in HALO Offshore UK Ltd

Orcadian Energy (AIM:ORCA) is pleased to announce that, the company has now completed the sale of 50% of the ordinary shares of HALO Offshore UK Ltd ("HALO") to The Independent Power Corporation Plc  ("IPC"). Peter Earl and Mark Preece have been appointed to join Steve Brown and Alan Hume on the board of HALO.

As announced on 13 December 2024, Orcadian and IPC intend to seek production acquisition opportunities for HALO with a preference for low-emissions, non-operated, gas producing licences.

Since 2013 HALO has incurred around £50 million of pre-trading capital expenditures which we expect will generate, on commencement of a ring-fence trade, tax allowances in the region of £115 million when Ring Fence Expenditure Supplement is applied.

In addition, IPC has entered into a loan agreement with HALO for up to £539,000 so that HALO can evaluate and negotiate gas producing licence interests. HALO has reimbursed Orcadian for costs incurred on behalf of HALO and IPC. Orcadian has pledged its share of HALO as security for its 50% share of this loan.

IPC has also agreed to provide, or procure the provision of, non-dilutive funding of at least £5 million; and has also agreed to provide, or procure the provision of, additional dedicated funding lines to finance acquisitions.

About Orcadian Energy

Orcadian is a North Sea focused, low emissions, oil and gas exploration and development company. Orcadian may be a small operator, but it is also nimble, and the Directors believe it has grasped opportunities that have eluded some of the much bigger companies. As we strike a balance between Net Zero and a sustainable energy supply, Orcadian intends to play its part to minimise the cost of Net Zero and to deliver reliable energy to the UK.

Orcadian's key asset is the Pilot oilfield, Pilot was discovered by PetroFina in 1989 and has been well appraised. The field has excellent quality reservoir and contains 263MMbbl of a viscous oil ranging in gravity from 17º API in the South of the reservoir to 12º API in the North. In planning the Pilot development, Orcadian has selected polymer flooding and wind power to transform the production of viscous oil into a cleaner and greener process. Polymer significantly reduces fluid handling requirements and hence energy consumption as well as boosting recovery. Ithaca Energy, operator of the Captain field in the Inner Moray Firth, has enjoyed consistent success in applying polymer flood to the highly analogous Captain field. Following the recent farm-down of Pilot, the project is now under the stewardship of Ping Petroleum UK PLC ("Ping") and is intended to be amongst the lowest carbon emitting oil production facilities in the world.

Ping is progressing a low-emissions, phased, field development plan for Pilot based upon a polymer flood of the reservoir, a Floating Production Storage and Offloading vessel (FPSO) and provision of power from a floating wind turbine or a local wind farm.

Orcadian has an 18.75% fully carried interest in licence P2244 (block 21/27a) and a 100% interest in licence P2482 (blocks 28/2a and 28/3a). Ping is operator of P2244 and the Pilot development project.

Orcadian was awarded three licences in the 33^rd round. The Mid-North Sea High licence, P2650, contains shallow gas leads. Orcadian applied in partnership with Triangle Energy, an Australian listed energy company. Orcadian is licence administrator and holds 50% of the offered licence. The Mid-North Sea High licence covers blocks 29/16, 29/17, 29/18, 29/19, 29/21, 29/22, 29/23, 29/27 and 29/28.

The Fynn licence, P2634, contains a very substantial heavy oil discovery. About 88% of the resource on a best technical case is estimated to lie within the area of the offered licence. Orcadian has a 50% working interest in the Fynn licence which is operated by the Parkmead Group. The Fynn licence covers blocks 14/15a, 14/20d and 15/11a.

The SNS licence, P2680, 50% Orcadian on completion of a proposed transaction, contains the Earlham discovery, a low-calorie gas discovery with 114bcf of methane resources on a P50 basis, the Clover prospect which has P50 prospective resources of 153bcf, and the decommissioned Orwell field which has redevelopment potential, alongside a number of smaller prospects. The Marine Low Carbon Power Company Ltd, an affiliate of IPC is intended to own the other 50% of P2680 and will carry Orcadian to first gas.
