MANCHESTER, UK – Enegi Oil has obtained 250 sq km (96 sq mi) of processed 3D data over its Phoenix block in the UK central North Sea.
The company plans in-house interpretation, subsurface analysis, and reservoir modeling to determine potential oil reserves recoverable from the Phoenix discovery. This will incorporate analysis that Azimuth is performing under the terms of a recent farm-in agreement.
Independently, Azimuth will evaluate additional exploration potential on the block that could lead to further development activity; prospects include “Lead A” and “Manx.”
Shell discovered Phoenix in 2004 with 22/12a-10, with estimated in-place oil of 93 MMbbl. It is a low-relief dip-closed structure on the Forties-Montrose High, between Shell’s Nelson field 16 km (10 mi) to the northwest and Talisman’s Montrose field 12 km (7 mi) to the southeast.
The Phoenix reservoir is on trend with the Forties, Montrose and Nelson fields, and is known to share many of their properties. The relatively nearby Arbroath and Arkwright fields are also thought to be analogous, sharing the same Palaeocene sandstone formation and producing light sweet crude in the API 38-42° range.
Recovery factors have ranged from 57% for Forties to 34% for Arkwright. Permeability and porosity levels across these fields are also considered strong, helping flow rates.
