What we do
Orcadian’s strategy is to secure discovered resources at low cost and to transform those resources into reserves and onto production
The Pilot field is our key asset. The field is well appraised and ready for development, Orcadian has selected, as the very best development concept, a low salinity polymer flood with two wellhead platforms, a dedicated FPSO, and a floating wind turbine. The next step is to secure development partners (either operators or an alliance of contractors) so that we can deliver a fully financed FDP to the NSTA.
To support the NSTA’s Net Zero initiative we have significantly reduced process heat demands by including heat pumps in our process design and we have selected a floating wind turbine to provide power backed up by highly efficient gas fuelled reciprocating engines to ensure a continuous power supply.

79 mmbbls
Proven plus probable reserves
Pilot is well appraised and development ready. Orcadian has submitted a Concept Select Report to the NSTA based upon a low salinity polymer flood, the NSTA issued a Letter of No Objection in November 2021 and Orcadian submitted a draft FDP in June 2022, the field will be developed using an FPSO and two wellhead platforms with power supplied by a floating wind turbine.
53 mmbbls
2C contingent resources
The Elke & Narwhal discoveries can be developed using two wellhead platforms tied back to the Pilot FPSO. There are also significant appraisal opportunities on the Elke discovery with contingent resource upside of over 22 mmbbls and prospective resource potential of 61 mmbbls.
25 mmbbls
2C contingent resources
This licence contains the Blakeney discovery (25 mmbbls, 2C) which can be developed using a wellhead platform tied back to the Pilot FPSO and some minor discoveries. There is also the prime exploration opportunity on our acreage, the 43 mmbbls Bowhead prospect, and channels which may be part of Pilot.
29 mmbbls
2C cont. resources, mgt estimate
Fynn – Andrew is estimated to hold 50 mmbbls in place, while the heavy oil discovery Fynn – Beauly could hold between 600 mmbbls and 1,300 mmbbls in place, although only between 77 mmbbls and 202 mmbbls lie on this block. Parkmead operate this block which lies in the Outer Moray Firth.
How polymer flooding works
Play VideoPolymer primer
The addition of a small amount of polymer to the injection water increases the water viscosity. The viscosified water can then sweep the oil with a stable flood front which accelerates production and increases recovery.
In our process design all produced water will be reinjected, thereby avoiding the possibility of releasing any polymer into the sea, but the polymer we add to our injection water is commonly used as a flocculant in water and wastewater treatment, and as a soil conditioner, so is not considered terribly damaging to the environment.
