... oil. Multiple reservoir levels ranging in depth from 1000m to 3000m are nominally imaged using conventional surface 3D seismic technologies. Natural arctic surface features and man-made sub-surface activities produce local bodies of unfrozen sediment with anomalously low velocity in the surrounding...
