MASSY, France – CGG has started acquiring its latest broadband 3D multi-client survey in the presalt deepwater Santos basin offshore Brazil.
Santos VIII is designed to deliver data-sets that allow bidders to better evaluate presalt opportunities for the country’s upcoming presalt licensing rounds.
It will cover an area of more than 8,000 sq km (3,089 sq mi) close to the Peroba, Pau Brasil, and Boumerangue fields.
CGG will image the BroadSeis data using its full-waveform inversion (FWI) technology at its Rio de Janeiro subsurface imaging center, with the data then merged with the Constellation reprocessing project to provide a regional broadband image of the basin.
The company expects to issue fasttrack products late this year, with final products available during 2Q 2019.
Constellation is a 44,000-sq km (16,988-sq mi) program designed to upgrade CGG’s existing Cluster and Cluster Extension surveys with the company’s latest subsurface imaging techniques, including 3D deghosting with bandwidth extension and TTI FWI velocity model building, to provide detailed broadband presalt images.
CEO Jean-Georges Malcor said: “It is the latest installment of our contiguous volume of over 94,000 sq km [36,293 sq mi] of seismic data and integrated geologic studies that bridge the Santos and Campos basins to cover the entire presalt area.”
