OFFSHORE geophysical company Polarcus has started work on a major 3D multi-client survey over the Roebuck basin, offshore Western Australia.

The Polarcus Capreolus project will incorporate seismic acquisition over the Phoenix area of the basin that contains the recent Phoenix South-1 oil discovery.

The survey is using two high performance 12-streamer Polarcus vessels, Polarcus Amani and Polarcus Asima, operating in tandem in order to maximise production.

The Capreolus 3D multi-client project aims to provide a basin-wide high quality broadband 3D seismic dataset over 1.5 million hectares.

The basin is one of the few remaining underexplored parts of Australia’s North West Shelf and considered to have the potential to become a major new oil province.

The data acquisition phase is estimated at about eight vessel months (four calendar months), with the resultant data being processed through a pre-stack depth migration routine by DownUnder GeoSolutions in Perth.

Final data products are expected to be available within the second quarter of 2016.

The news came after Polarcus received another commitment for a broadband 3D marine seismic acquisition project in Australasia from a client it would not name.

The project, subject to the execution of a service contract, will commence in the first quarter of 2015 and is expected to run for about two months.
