Sercel has launched Sentinel HR, a high-resolution solid streamer designed to meet the specific imaging needs of shallow-target applications as well as high-resolution 3D (HR3D) seismic surveys for detailed mapping of geological features.
The Sentinel HR streamer has been developed with a close channel separation of 3.125 m.
Recent enhancements available in Sercel’s Seal 428 marine seismic recorder allow a higher channel count, enabling up to 6 km of Sentinel HR to be deployed with full data and power redundancy to ensure non-stop acquisition.
The Sentinel HR can provide marine mammal monitoring when combined with QuietSea, Sercel’s passive acoustic monitoring (PAM) system, which is integrated into the seismic streamers.
Pascal Rouiller, Sercel CEO, said: “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. 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.”
