Australia Cygnus Vulcan Sub-Basin 3D

With the Australian 2016 Federal Release, Polarcus Cygnus 3D Multi-Client survey in the Vulcan Sub-basin is in prime position to unlock further potential within this producing basin. 


The survey comprises 6,200 sq. km and is designed to provide a basin-wide, high quality broadband 3D-Seismic Dataset to exploration companies over this proven hydrocarbon province. The first phase was completed in 2016, providing new RightBAND™ multi-client data over the Vulcan Sub-Basin, offshore North-West Shelf, Australia.

Polarcus acquired this survey, in part in collaboration with Spectrum, in the structural dip direction using an XArray™ configuration: 10 x 112.5m x 8,100m with a 12.5m triple-source shot interval and continuous recording, delivering 33% improved cross line sampling without any interpolation.

The main exploration targets in the Vulcan Sub-basin are sandstones in the Upper Triassic Challis and Nome Formations, fluvio-deltaic sandstones of the Middle Jurassic Plover Formation, Oxfordian shoreface/barrier bar sandstones of the Montara Formation, Tithonian submarine fans of the upper Vulcan Formation and submarine fans of the Upper Cretaceous Puffin Formation. Plays occur in stratigraphic traps, pinchouts, unconformity truncations, tilted fault blocks, horst blocks and anticlines.

Historically, sub-optimal acquisition and processing strategies have not been able to address the geological and geophysical challenges, such as the energy absorption and multiple issues caused by the thick Late Cretaceous-Tertiary carbonates.
