Paris-headquartered geosciences company CGG said it has commenced a new, large, long-offset BroadSeis survey located in the Campos and Santos Basins, offshore Brazil.

The Nebula 3D survey is supported by industry funding.

With an initial focus on Brazil’s 15th License Round blocks, the data is being acquired by the Geo Caribbean and a portion of the survey will provide 3D data coverage where no other 3D data currently exists.

CGG Geoscience’s Subsurface Imaging Center in Rio will employ advanced data processing techniques to deliver improved imaging of pre-salt structures in these prolific basins, the company said.

Dechun Lin, EVP, Multi-Client & New Ventures, CGG, said, “Nebula will further expand our vast contiguous volume of data in the Santos and Campos Basins and interested clients will gain enhanced insight from our high-quality imaging to identify potential prospects over their purchased blocks in this highly prospective region.”
