MASSY, FranceCGG has delivered final time-processed data from its Northern Viking Graben multi-client 3D BroadSeis-BroadSource survey in the Norwegian North Sea.

This comprises more than 35,000 sq km (13,513 sq mi) of what the company described as “state-of-the-art subsurface images.”

The survey was acquired during 2014-2016 in response to industry interest in this area. The resultant broadband seismic data set provides contiguous and uniform coverage over a mature offshore region, where significant accumulations of hydrocarbons are still being discovered in the established Jurassic plays.

New plays are also emerging, as demonstrated byENGIE E&P’s Cara discovery last year.

High-resolution imaging of the shallow stratigraphy and improved imaging below the base Cretaceous Unconformity provides more accurate interpretation of potentially prospective reservoirs at all levels, CGG said.
