New advanced seismic data resolve the imaging challenges present on the Halten/Dønna Terrace in the Norwegian Sea and reveal the remaining potential in the region, write Kjetil Roverud, Stefan Möller and Jens Beenfeldt from

ALT Zoom in on the Urd field area and the Jurassic fault blocks imaged by a GeoStreamer X depth seismic line (Left). At an apex depth of ca. 1,830 m below seabed, high-impedance reflectors can be seen. These are caused by interbedded coals in the Åre Fm (blue arrow). Åre sandstones are proven reservoirs along with overlying Viking Group sandstones. A high degree of fault segmentation is obvious and critical in field development strategies. Note the difference in fault plane visibility, fault plane extent (orange arrows), and reflector termination against the faults (yellow arrows) compared with the single azimuth seismic (Azimuth 34) section in the section on the right.
