CGG starts OBN survey in U.S. Gulf of Mexico

French seismic company CGG has started its first multi-client ocean bottom node (OBN) survey in the U.S. Gulf of Mexico. The survey is being carried out in the north-central region of the Gulf of Mexico.

CGG said OBN survey would provide well-sampled, full azimuthal coverage with long offsets, “to deliver exceptional data for imaging the geologically complex structures in Mississippi Canyon.”

Acquisition services are being provided by Seabed Geosolutions and the data will be processed by CGG Geoscience’s Subsurface Imaging in Houston.

CGG said the survey would provide an improved definition of drilling targets, with preliminary data expected to be available in the third quarter of 2019.

“Supported by industry prefunding, CGG’s Mississippi Canyon Node survey paves the way for further CGG multi-client OBN surveys in the future,” CGG said.

Sophie Zurquiyah, CEO, CGG, said: “We are pleased to initiate our first multi-client OBN survey, in this strongly growing market, as clients take advantage of the enhanced geologic understandings that OBN data and advanced imaging can deliver.”

Seabed Geosolution, the company carrying out the survey, in a separate statement said the ocean bottom nodes would be deployed by remotely operated vehicles to 2,100-meter water depths, “illuminating a challenging target area in one of the deepest offshore production areas in the world.”

Stephan Midenet, CEO, Seabed Geosolutions: ‘We are excited to embark on our first OBN project with CGG over the highly prospective Mississippi Canyon area using our proven CASE Abyss node technology. The survey will combine our expertise in ocean bottom seismic operations with CGG’s advanced OBN imaging technology and experience.’
