The CGG marine seismic fleet has the largest deployment of Sercel Seal Sentinel® solid streamers in the industry. These streamers are recognized for their low-noise properties and low frequency recording capabilities, providing better signal penetration and benefitting sub-salt, sub-basalt and deep target imaging.
Sentinel is the quietest marine streamer available to-day, with a design that reduces noise and drag. Sentinel is the streamer of choice for consistency, reliability, high signal-to-noise ratio and low frequency recording, as CGG can tow these at up to 50m depth, for the deepest tow in the industry. They are proven in environmentally sensitive areas such as the Arctic, as they are robust and do not leak. Sentinel streamers are deployed throughout the CGG fleet.
In the Sercel Sentinel solid streamer there is a single stress member at the core, isolated from the hydrophone by the PU foam. In fluid or gel streamers the hydrophone is at the core, and is coupled to the strain members. This means that solid streamers do not suffer from towing and environmental noise. This lower noise floor provides a better signal-to-noise ratio at low frequencies, allowing the use of lower low-cut filters. In a vibration tank test solid streamers are 12dB less noisy than gel streamers at 5Hz.
Better 3D coverage, improved 4D repeatability, reduced infill. Integrated streamer control with acoustic positioning, depth control and automatic steering.
Environmentally friendly C-Class vessels. Extreme conditions are no match for our solid streamers. Our people are resourceful. Our experience is deep.
