Description of business
Orcadian Energy (AIM:ORCA) is a North Sea focused oil and gas development company with five production licenses on the UKCS. The Company’s key asset is the 18.75% carried interest in the Pilot oilfield, with proven and probable gross reserves of 79 million barrels (audited by Sproule BV). The Company also has 53 million barrels of 2C contingent resources (development on hold) in the Elke and Narwhal discoveries, a 50% interest in the Fynn Beauly and Lowlander discoveries (operated by Serica), a 50% interest in gas prospects in License P2650 on the mid North Sea high and a 100% interest in the Earlham discovery and the Orwell redevelopment opportunity in the Southern North Sea.
The Group’s strategy is to license a portfolio of discovered resources, preferably well appraised and most likely on the UKCS, and to create profitable field development plans which attract finance either from oil industry partners or financial investors.
Orcadian is listed on the Alternative Investment Market (“AIM”) of the London Stock Exchange under the stock symbol ORCA.
