Polarcus and Spectrum have kicked off a new 3D multi-client project over the Vulcan Sub-basin, offshore North West Shelf, Australia. Separately, Polarcus has been awarded a broadband 3D project in South America. 

According to Polarcus, the Cygnus 3D survey, offshore Australia, is being acquired with joint investment from Spectrum and DownUnder GeoSolutions, and is supported by industry funding. The survey will comprise a minimum 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.

The geophysical company said on Wednesday that, historically, sub-optimal acquisition and processing strategies have not been able to address the geological and geophysical challenges including the energy absorption and multiple issues caused by the thick Late Cretaceous-Tertiary carbonates.

The company says it will acquire this survey using a 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 with real data (no interpolation).

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, Polarcus said.


3D project in South America

Furthermore, Polarcus said on Wednesday it has received a memorandum of understanding (MOU) from an undisclosed client for a 3D marine seismic project in South America. The company will be utilizing its RightBAND technique for broadband data acquisition.

The project will start in Q1 2016 and will run for approximately four months.
