The Luno Discovery, Imaging Outside the Mute Zone

The area around southern part of the Utsira High in the Norwegian sector of the North Sea has been a repeated target for exploration ever since the first well (16/2-1) was drilled in 1967. For the last 6 years this has been a main focus area for Lundin Norway. Three substantial discoveries has been made on and around this part of the Utsira high (The Haugaland High) with Lundin Norway as operator (Figure 1). The combined contingent resource estimate of the Luno, Avaldsnes and Apollo discoveries are reported to be in the order of 200-615 MMboe. For many years, this area has proven to be very challenging to image by the use of conventional streamer seismic as the reservoir is situated directly below a thin high velocity Chalk layer. To address the seismic imaging problem a small wide-azimuth, multi-component seafloor seismic data-set was acquired over the Luno field proper during the summer of 2008. During the summer of 2009 and 1660 km2 combined gravity and Geostreamer survey was acquired to cover the entire Haugaland high.
