FRENCH seismic company CGG has started acquiring data in its Davros 3D multi-client survey in the Northern Carnarvon basin on the North West Shelf off Western Australia.

Covering over 1.1 million hectares, Davros is the largest seismic survey ever to be acquired by CGG in the Asia-Pacific region.

CGG chief executive Jean-Georges Malcor said he believed the Davros survey would reveal exciting new exploration opportunities, given its location adjacent to significant discoveries along the Rankin Trend.

“It will significantly enhance interpretation of the area’s Triassic to Lower Cretaceous reservoir units, which exceed 10 kilometres in thickness and are expected to host significant quantities of hydrocarbons, as has been confirmed by these previous discoveries,” he said.

The survey is being conducted by the Viking Vision, using CGG’s BroadSeis variable-depth streamer configuration and BroadSource synchronised broadband multi-level source.
