Australia Capreolus Roebuck Basin 3D

Icollaboration with DownUnder GeoSolutions, we have completed a major new basin-wide RightBAND multi-client 3D  seismic program across the Roebuck and Northern Carnarvon Basins, offshore North-West Shelf, Australia, delivering optimum  imaging of  this highly prospective area.

We acquired an area of 22,200 sq. km of high resolution broadband 3D seismic data, including coverage over the recent Phoenix South-1X oil field discovery in an area previously assumed to be gas prone. This oil discovery has opened up a new oil-prone fairway within one of the few remaining underexplored sections of the North-West Shelf. The Capreolus 3D survey enables reduced risk and play-based exploration targeting Triassic and Jurassic structural and stratigraphic targets.

The survey was acquired over an eleven-month period by Polarcus Asima, Polarcus Amani and Polarcus Naila in 12 x 100m x 8100/9000m configurations, with 12.5m flip/flop shot interval and 12s record length, providing an unparalleled 162 to 180 fold. Data processing has been completed five months ahead of schedule, using the DownUnder GeoSolutions broadband Pre-SDM workflow.

 

New Interpretation Study

 

Polarcus is pleased to announce the completion of an interpretation study covering the 22,200 sq. km Capreolus 3D multi-client survey, offshore north-west Australia.

The interpretation study, completed by Clearview Oil and Gas Pty Ltd in collaboration with Polarcus and DownUnder GeoSolutions, provides a detailed overview of the geology and prospectivity across the data set, which spans the area from the North Carnarvon Basin across the Thouin Graben into the Bedout Sub-Basin. The recently announced successful flow test of the Roc-2 well from the Triassic Caley Formation has provided further evidence of the prospectivity of the area. The report has highlighted a number of new and emerging plays; this is a result of regional review, mapping of key structural and stratigraphic elements, migration modelling and an interrogation of the seismic, including gathers for presence of DHI’s, several of which are illustrated in the report. The report covers the full extent of the Capreolus 3D area in detail and includes the time and depth seismic picks along with key faults and a well database of tops and picks. Further geochemical modeling work is included, both in the form of maps in the report and as a Trinity (Zetaware) project.
