CGG Starts Ocean Bottom Node Survey in Mississippi Canyon, GoM

CGG announces commencement of its first multi-client ocean bottom node (OBN) survey, taking CGG’s offshore data library to the next level of excellence. Located in the north-central region of the Gulf of Mexico, this dense OBN survey will 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. Implementation of CGG’s most advanced OBN processing techniques will provide a fine-tuned velocity model and improved definition of drilling targets. Preliminary products will be available in Q3 2019, and final products are expected in Q1, 2020.
