Source Steering

CGG's proprietary integrated vessel and source steering complements quiet, Nautilus-steered Sentinel solid streamers to deliver high repeatability at the surface with minimized acquisition artefacts as part of our advanced 4D marine acquisition toolbox. On its own our source steering system (SSS) delivers a positioning accuracy of 3m, but in combination with the integrated vessel steering this is reduced to less than 2m.

DSS

Benefits

Powerful integrated source and vessel steering enables sources to be positioned more accurately to match the pre-plot better. The improved source positioning combined with Nautilus streamer control for accurate receiver positioning delivers increased 4D geometric repeatability.

Improved repeatability delivers a clearer 4D signal with less 4D noise, enabling weaker 4D signals to be detected and so delivering better data for more accurate dynamic reservoir models.
