CGG Announces Availability of over 35,000 sq km of Broadband High-Resolution Images across the Northern Viking Graben

Paris, France - 21 November 2017

CGG announced today delivery of the final time-processed data from its Northern Viking Graben multi-client 3D BroadSeis(TM)-BroadSource(TM) survey. This new product offers exploration companies over 35,000 sq. km of state-of-the-art subsurface images across the Norwegian Northern North Sea.

The Northern Viking Graben survey was acquired from 2014-2016 after receiving strong industry support in this area of high exploration activity. This vast new broadband seismic data set provides contiguous and uniform coverage over this highly productive area of the Norwegian Continental Shelf (NCS). It offers the industry a powerful tool for further exploration in this mature region, where significant accumulations of hydrocarbons are still being discovered in the established Jurassic plays, and new plays are also emerging, as demonstrated by the Cara discovery last year. High-resolution imaging of the shallow stratigraphy and improved imaging below the Base Cretaceous Unconformity deliver more accurate interpretation of potentially prospective reservoirs at all levels.

Processed with CGG's latest broadband subsurface imaging technologies, the resulting high-resolution images are state-of-the-art, delivering a structurally continuous "backbone" for CGG's Northern Viking Graben JumpStart(TM) geoscience package integrating key geological and geophysical data.

Jean-Georges Malcor, CEO, CGG, said: "The Northern North Sea is one of the world's most prolific hydrocarbon provinces and is expected to hold significant remaining resources. CGG's expansive Northern Viking Graben data set creates a new baseline for future activity in the region, benefitting players at all E&P stages, from early exploration to development and production."
