Cygnus: New 3D Multi-Client Project Offshore Australia 17 Dec 2015

Spectrum has announced the commencement of a new 3D Multi-Client project over the Vulcan Sub-basin, offshore North West Shelf, Australia, which is adjacent to Spectrum’s Cartier Main 3D survey, acquired in 2010 and recently reprocessed to broadband PSDM.

The Cygnus 3D Survey is being acquired in collaboration with Polarcus and DownUnder GeoSolutions, and is supported by industry funding. The survey will comprise a minimum of 4,000 sq. km and is designed to provide exploration companies with a basin-wide high quality broadband 3D seismic dataset over this proven hydrocarbon province.

Polarcus will use its XArrayTM configuration with a 12.5 m triple source shot interval and continuous recording, delivering 33% improved cross line sampling. Processing will be done by DownUnder GeoSolutions through a broadband Pre-SDM workflow and final processed data will be available from Q3 2016, with Pre-STM fast track data available from Q1 2016.

With this latest survey, Spectrum’s 3D coverage in the Australian North West Shelf will total 40,000 sq. km of newly acquired 3D multi-client data (less than five years old).

Spectrum currently holds a total of 133,000 sq km of 3D seismic data and over 250,000 km of 2D data offshore Australia, predominantly on the North West Shelf.
