IsoMetrix marine isometric seismic technology provides a spatially dealised broadband product in all 3 dimensions: in-line, cross-line and depth. This fine-scale resolution of the wavefield in all directions can translate directly to fine-scale resolution of geology in all directions, enabling a more accurate representation of the subsurface. In a North Sea case study, a workflow that included full waveform inversion and reflection tomography achieved a detailed velocity model that accurately resolved near-surface heterogeneity and improved the imaging of a target formation compared to previous vintages of towed streamer seismic and an ocean bottom cable survey.
