UK-based exploration junior Enegi Oil says a self-installing floating tower (SIFT) would be the best development option for the central North Sea Phoenix discovery.
Enegi’s preference for a SIFT follows a work program by Azimuth Limited, carried out as part of a farm-in deal announced last year. The work involved analyzing 3D seismic and well data on Block 22/12b, containing Phoenix.
Based on the results of the subsurface studies, Enegi looked at using a SIFT or a production buoy development solution. It said the SIFT solution offered “the most appropriate technical and economic development solution for the field.”
Enegi is also working on plans for a SIFT on the Fyne field, as part of a farm-in agreement with Anrtim Energy, which it says will help inform engineering on the Phoenix field. Read more: Unmanned buoy concepts grow
Enegi said: “The results to date are very encouraging, as seismic and local well studies are able to resolve and prove the presence of oil-bearing Forties reservoir around the previously drilled 22/12a-10 exploration well. The Partners' efforts are now focused upon resolving the volume of oil contained by the stratigraphic closure in the surrounding area.”
The development scenarios being considered for Phoenix include the number of production wells and possible requirements for water injection.
The Phoenix field is a Palaeocene-aged Forties sandstone between the established Nelson and Montrose fields.
