Abstract

Ocean-bottom seismic (OBS) data has recently been acquired over the Njord field with a view to improving the image for the seismic interpreter. Comparisons between OBS and previous generations of streamer data show that faults can be placed with significantly higher confidence on the former dataset. This results from improved definition of rotated Jurassic/Triassic fault blocks, assigned in part to the rich azimuthal illumination associated with the OBS acquisition. Additional structural details contained in the OBS data also emerge using automated trace analysis techniques such as coherency. As such, OBS data acts as a powerful tool to reduce the residual structural uncertainty on the highly compartmentalised Njord field.
