Petrobras has chosen CGG to process seismic data from a 3-D ocean-bottom node (OBN) survey covering 2,180 sq km in Brazil’s deepwater Santos Basin, a news release said.

CGG said this survey will be the largest node survey ever acquired and processed in the industry.

The survey will be acquired by Seabed Geosolutions, CGG’s joint venture with Fugro. The dataset will be processed in CGG’s Rio de Janeiro Subsurface Imaging Center, the release said.

“CGG is a natural choice for this high-profile OBN processing contract given our in-depth geological knowledge of the Santos Basin and our recognized track record and proven advanced technologies for OBN processing,” CGG CEO Jean-Georges Malcor said. “OBN surveys are one option at present for acquiring full-azimuth data offshore Brazil and we will work closely with Seabed Geosolutions to deliver the best images of the subsurface in the highly prospective Santos Basin.”
