Sercel has launched Sentinel HR, a high-resolution solid streamer designed to meet the specific imaging needs of shallow-target applications, such as oceanology, civil engineering and reservoir characterization, as well as high-resolution 3D (HR3D) seismic surveys for detailed mapping of geological features, announced CGG.
The latest member of the Sentinel streamer family has been developed with a close channel separation of 3.125m to achieve reliable and cost-effective high-resolution surveys. Recent enhancements available in Sercel’s new-generation Seal 428 marine seismic recorder allow a higher channel count, enabling up to 6km of Sentinel HR to be deployed with full data and power redundancy to provide non-stop acquisition, opening up new possibilities for HR3D survey configurations.
The Sentinel HR adapts to all types of survey spreads, from comb deployment to larger configurations integrating the Nautilus steering system. In addition, the Sentinel HR can also provide marine mammal monitoring when combined with QuietSea, Sercel’s revolutionary Passive Acoustic Monitoring system, which is integrated into the seismic streamers.
“Sercel’s Sentinel HR is a robust new member of our Sentinel product family that will help to achieve a better understanding of subsurface geology for a broad range of industries,” said Pascal Rouiller, CEO, Sercel. “Built on field-proven technology recognized by the global seismic industry, the Sentinel HR is a cost-effective and powerful tool for both exploration and field development that will meet the intrinsic requirements of a wide range of specific shallow-target market applications.”
