Ocean Bottom Seismic

CGG can process your ocean bottom seismic (OBS) data to the highest possible standard. We have the necessary breadth and depth of resources and expertise to process and image all kinds of ocean bottom seismic: ocean bottom cable (OBC), ocean bottom nodes (OBN) and permanent life-of-field data. We have experience working with data from all over the world and can handle any challenges unique to each location. In addition, we offer a full range of the latest interpretation and reservoir services, ensuring we can provide the full solution for your ocean bottom seismic data. Our extensive experience of integrating your seabed data with, and processing alongside, your marine streamer data brings benefits such as enhanced coverage, improved imaging and 4D applications.

Recent Developments

OBS processing benefits from the latest techniques such as:

  • Joint PP and PS processing and joint velocity model building
  • OBN water column statics (deep water)
  • Broadband OBN processing
  • PS least squares depth imaging and PS-CBM
  • Joint PP and PS elastic inversion
  • Vector Vista 4.0 software, offering the full range of 4C data analysis and interpretative tools in an interactive package
