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.
Nautilus® is a powerful 3-in1 integrated streamer control system providing:
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.
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.
Our source steering system:
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.
Better 3D coverage, improved 4D repeatability, reduced infill. Integrated streamer control with acoustic positioning, depth control and automatic steering.
Best signal-to-noise ratio. Lowest frequencies. Most reliable 4D. Widest weather window. Broadband ready. For the most demanding applications, choose Sentinel.
