Sercel launches Sentinel HR, a high-resolution seismic streamer

Sercel Sentinel HR PRThe Sercel Sentinel HR. (Image source: CCG)CGG announced on 4 April that 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 characterisation, as well as high-resolution 3D (HR3D) seismic surveys for detailed mapping of geological features

The latest member of the Sentinel streamer range has been developed with a close channel separation of 3.125m to achieve high-resolution surveys. Sercel’s new-generation Seal 428 marine seismic recorder allows for 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, opening up new possibilities for HR3D survey configurations.

Drawing on the commercial and operational success of the well-established Sentinel solid streamer family, which has over 40,000 streamer sections deployed in the field to date, offering great reliability. Delivering a high-quality signal-to-noise ratio and pressure measurements from its hydrophone sensors, the Sentinel HR has been designed to meet the challenges of high-resolution surveys, enabling the detailed imaging of complex subsurface geology.

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 Passive Acoustic Monitoring (PAM) system, which been 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.”
