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.

Viscous oil

As part of its viscous oil strategy Orcadian has an 18.75% carried interest in the Pilot development project, Pilot was discovered by PetroFina in 1989 and has been well appraised. The field has excellent quality reservoir and has contingent resources of 79 MMbbl 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. P2482 covers the Elke and Narwhal discoveries which contain 54 MMbbl of contingent resources.

The Fynn licence was awarded in the 33^rd round, 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 P2634 licence. Orcadian has a 50% working interest in the Fynn licence which is operated by Serica. The Fynn licence covers blocks 14/15a, 14/20d and 15/11a.

Gas

Orcadian was awarded two gas 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 SNS licence, P2680 100% Orcadian, contains the Earlham discovery, a low-calorie gas discovery with 114 bcf of methane resources on a P50 basis, the Clover prospect which has P50 prospective resources of 153 bcf, and the decommissioned Orwell field which has redevelopment potential, alongside a number of smaller prospects. Orcadian has established Earlham Gigagrid to provide a vehicle for investment in the Earlham development, power station and datacentre potential, without diluting Orcadian's shareholders' interests in its viscous oil and Central North Sea projects.
