Integrated geoscience company CGG has started its acquisition of a 3D broadband survey, Santos VIII, in the pre-salt area of the deepwater Santos Basin off the coast of Brazil.
The multi-client survey is part of CGG’s ongoing pre-salt programme and is expected to deliver ultramodern seismic data that allows bidders to better evaluate pre-salt opportunities for Brazil’s pre-salt licensing rounds.
It will cover an area of more than 8,000km² near the Peroba, Pau Brasil and Boumerangue fields.
The company will use its full-waveform inversion (FWI) technology at its Rio de Janeiro Subsurface Imaging Center to image the resulting BroadSeis data.
Thereafter, the data will be merged with the Constellation reprocessing project to provide a regional broadband image of the basin.
CGG CEO Jean-Georges Malcor said: “The addition of Santos VIII will extend our world-class broadband data coverage in the highly prospective deepwater Santos Basin.
“It is the latest instalment of our contiguous volume of over 94,000km² of seismic data and integrated geologic studies that bridge the Santos and Campos Basins to cover the entire pre-salt area.
“These multi-client data sets are an essential resource for oil and gas companies to complete a detailed picture of the complex Santos Basin in advance of Brazil’s future licensing rounds.”
The company aims to offer fast-track products in the fourth quarter of this year, while final products are expected to be available in the second quarter of next year.
Constellation is a 44,000km² project that aims to upgrade the company’s existing Cluster and Cluster Extension surveys with its latest subsurface imaging technology, in order to deliver detailed broadband pre-salt images.
