Polarcus at 50% completion on Capreolus

Oilfield Technology,

Polarcus has now reached the 50% completion milestone in the acquisition of the Capreolus 3D multi-client project, the largest single 3D survey ever acquired offshore Australia.

Survey details

Polarcus will acquire a minimum area of 22 130 km2 of high resolution broadband 3D seismic data including coverage over the Phoenix South-1 oil discovery and surrounding blocks in an area previously assumed to be gas prone. The 2014 Phoenix South oil discovery in permit WA-435-P has opened up a new oil-prone fairway within one of the few remaining underexplored parts of the northwest shelf. The Capreolus 3D survey will provide multiple opportunities for reduced risk and play-based exploration targeting Triassic and Jurassic structural and stratigraphic traps.

Data currently being processed

Seismic acquisition commenced early January 2015 with two Polarcus A-Class 3D seismic vessels, Polarcus Amani and Polarcus Asima, operating in simultaneous acquisition mode in order to maximise production. This operating technique has delivered over 11 000 km2 of 3D seismic data in less than three months. The data is currently being processed through to pre-stack depth migration by DownUnder GeoSolutions (DUG) in Perth, Australia, with final data products expected to be delivered within 1Q16.
