OFFSHORE WEST GREENLAND NON-EXCLUSIVE SEISMIC DATA
|
|  |
9460 km data provide an integrated regional grid covering major play types off West Greenland
943 km data form a prospect survey over the Kangāmiut Ridge around the Kangāmiut-1 well (K-1). Data reprocessed in 1999/2000
711 km regional data in the Disko Bay area for sale at a reduced price
Data acquired 1990, 1991, 1992 and 1995 using tuned airgun arrays; recording to 8 s at 2 ms intervals on 3000 m cable with 120 channels (240 to 360 channels 1995)
Processing with special emphasis on removal of strong seabed multiples and migration of the 60 fold stack

FURTHER INFORMATION
The seismic data can be inspected at GEUS's office in Copenhagen on a Landmark workstation. GEUS can also give presentations of the geology offshore West Greenland either at GEUS's Copenhagen offices or at companies' own offices. For all presentations, appointments should be made in advance.
Information regarding licensing policy, licensing terms, and legal and economic matters concerning hydrocarbon and mineral exploration and exploitation in Greenland can be obtained from the Bureau of Minerals and Petroleum in Nuuk, Greenland.
Prices
The price for the seismic data is US$ 60 per km. There is no minimum
sale, but only complete lines can be purchased. However, lines exceeding
200 km may be purchased in portions minimum 100 km long. Data from the
Disko Bay area can be obtained at 25% of the above prices. GEUS offers
discounts for purchase of large amounts of data. Data is available as
1:50,000/5 cm/s films, SEG-Y tapes or Landmark workstation tapes.
Further details can be obtained from GEUS (contact info-data@geus.dk).
