The Duomonte Prospect consists of two similar sized lobes, one in WA-254-P the other in adjacent WA-1-P. WA-254-P potential ranges from 20 (mean) to 44 million barrels of oil recoverable (P10) with primary target formation (pre recent seismic developments) being shallower Legendre Formation sands at approximately 2,500 metres depth. A nearby well Janus #1 targeted Legendre sands at a shallower depth than Duomonte and these sands were found to be water wet with oil shows.

A revised look at the seismic data suggests the younger and shallower Calypso Formation sands are also a secondary target, but could be gas prone. New (Panaeus refresh) seismic data suggest deeper seismic events in structure now also need assessment at North Rankin and Mungaroo levels for a Caribou gas (oil) target before Duomonte is drilled.

WA-254-P was renewed on the 12 June 2006 for a further term of five years.
