Denmark 3D is a multi-client reimaging program that covers about 10,650 km2 of the Danish offshore area, from the Mid North Sea High to the Tail End Graben, in quadrants 5605, 5604, 5603, 5503, 5504 and 5505 of the Danish North Sea. This 3D dataset is comprised of multiple contiguous vintage surveys that are currently being reprocessed to create a continuous regional volume from field tapes to PSDM. Phase 1 will combine three different existing legacy surveys, and will be completed in January 2020. The aim of this phase is to boost exploration activity by providing a modern, affordable 3D depth-imaged data set.


The North Sea is one of the most prolific hydrocarbon basins in the world and the Danish sector has been producing oil and gas for nearly five decades, with numerous hydrocarbon discoveries totaling over 100 MMboe recoverable reserves from nearly 20 fields. Therefore, this varied and interesting geological setting, with plays in multiple stratigraphic intervals, makes Denmark the perfect location to demonstrate the value of a regional depth reprocessing project.


Denmark 3D provides solutions to imaging challenges associated with the HPHT prospectivity, Chalk-Jurassic interface and new emerging Paleozoic play types. The larger of Denmark’s producing discoveries were found across multiple stratigraphic levels, ranging from Early to Late Jurassic, and Lower and Upper Cretaceous, predominantly within the chalk, while a significant number of smaller discoveries have been made within the Permian, Triassic and Palaeogene clastics.

ION is leveraging proprietary processing experience and latest processing flows to tackle these challenges to provide a product that will support the industry as they seek to maximize the value of these remaining reserves.
