Below is a summary of the Company's licence portfolio, to provide investors with a clear overview of the Company's operations, strategy and near-term catalysts ahead of the session.

Pilot field, P2244, 18.75%

Pilot was discovered by PetroFina in 1989 and has been well appraised. The field has excellent quality reservoir and has gross 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 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.

Orcadian successfully farmed out operatorship of the project to Ping Petroleum UK PLC ("Ping"). Ping is progressing a low-emissions, phased, field development plan for Pilot based upon a polymer flood of the reservoir, work by Ping in 2025 has confirmed Orcadian's previous estimates of potential recovery from this field and Ping continues to progress the concept select process with NSTA.

Earlham and Orwell , P2680, 100% Orcadian,

P2680 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, and could deliver 30 bcf of resources, alongside a number of smaller prospects.

Orcadian, with its proposed partners The Independent Power Corporation plc ("IPC") and The Marine Low Carbon Power Company Ltd ("MLCP"), intends to develop Earlham to supply gas to a power station to be constructed by MLCP and located adjacent to the field. The generated power is currently planned to be exported to data centres located on the M25 corridor, where demand for clean, dispatchable electricity has risen beyond the grid's current capacity. Carbon dioxide produced from the reservoir and from the combustion of gas is intended to be reinjected into the Earlham field to maintain reservoir pressure and to enhance gas recovery

Orcadian has a 100% interest in Licence P2482 (blocks 28/2a and 28/3a). P2482 covers the Elke and Narwhal discoveries which contain 54 MMbbl of contingent resources and a further 52 MMbbl of high chance of success, prospective resources. The Elke and Narwhal fields are potential satellite/tie-back opportunities to the Pilot FPSO. Orcadian will be seeking potential farm-out partners for this licence which has the potential to deliver over 100 MMbbl of resources.

Fynn Beauly, P2634, 50%

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 licence. Orcadian has a 50% working interest in the Fynn licence which is operated by Serica Energy. The Fynn licence covers blocks 14/15a, 14/20d and 15/11a. The Fynn Beauly discovery has gross 2C resources of 292 MMbbl, 129 MMbbl net to Orcadian within P2634.

Orcadian and Serica are working jointly to complete the work programme and lay out a path for future development of this opportunity.

Lowlander, P2634, 50%

Lowlander is a well appraised oilfield with light oil contingent resources estimated to lie in the low to mid-twenties. Development has been stymied because of the high hydrogen sulphide content of the oil, Orcadian believes that a solution to this issue can be designed and that a tieback of Lowlander to nearby existing or future infrastructure can unlock this discovery.

Glenlough and Breckagh, P2650, 50%

P2650, the Mid-North Sea High licence 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 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. Orcadian is evaluating the potential use of an electro-magnetic survey to address the main risk on these licences which is that gas saturations are low, but still create seismic amplitude anomalies.
