Advanced 4D Marine Toolbox

CGG’s advanced 4D marine acquisition package delivers optimal positional repeatability from powerful integrated source, vessel and streamer steering systems. The real-time onboard QC system combines positional validation with illumination repeatability monitoring, source signature stability QC and automatic reshoot prioritization. This toolbox is fully compatible with BroadSource™ and BroadSeis™, to provide the optimum 4D towed-streamer acquisition platform.

receiver steering

Steering the spread to match the base

Nautilus® is a powerful 3-in1 integrated streamer control system providing:

  • acoustic positioning
  • depth control 
  • automatic streamer steering

Enabling accurate receiver position repeatability. The CGG Dovetail™ fanned streamer solution can improve the repeatability of the receiver positions of the survey in areas with challenging currents.

Integrated source and vessel steering

Our proprietary source steering system is automatically driven by Sercel’s SeaPro Nav navigation system and is integrated with vessel steering for optimal source repeatability.

source steering

Our source steering system:

  • Corrects  up to +/- 20 meters laterally for each source independently
  • Includes an underwater system, a steering algorithm and monitoring
  • Is fully compatible with BroadSource

Complete 4D solutions

Our 4D acquisition is complemented by our world-leading 4D processing expertise, SED (Survey, Evaluation and Design) and reservoir capabilities to provide optimal quantitative studies of your reservoir. Our efficient proprietary new 4D co-processing technique provides backwards and forwards compatibility for all geometries, including BroadSeis.
