The MegaSurvey in Australia
The Carnarvon MegaSurvey covers 50 000 sq.km of fully matched and merged contiguous 3D seismic data in the Carnarvon Basin(encompassing parts of the Exmouth, Barrow, Dampier and Beagle Sub-basins).
The key regional seismic events are interpreted, all major wells are tied and the single balanced dataset allows explorationists to obtain a fully integrated regional overview in the major oil- and gas-producing basin of the North West Shelf.

The Vulcan MegaSurvey comprises 18 500 sq.km of fully matched and merged 3D seismic data in the Vulcan Sub-Basin, an oil-prone sector of the Bonaparte Basin, and the large areal coverage of a single, balanced dataset over known discoveries makes it possible to rapidly screen prospective intervals, while allowing a re-evaluation of both held and open acreage.
