The duo launched TopSeis on Monday at ONS 2016 in Stavanger. Based on an original idea from Lundin, the technology has been "specifically designed to overcome the intrinsic lack of near offsets inherent in 3D towed-streamer seismic", CGG said.

TopSeis has been developed over the last two years by undertaking synthetic modeling, field trials and conducting both a 2D and 3D pilot survey and is now a commercially-ready solution.
