PARIS –CGG has started to re-image all of its Cornerstone multi-client data to create 35,000 sq km (13,514 sq mi) of contiguous broadband PSDM volume in the Central North Sea.

An early fasttrack product will be available late 2013 as part of the planned 2014 delivery of 8,500 sq km (3,282 sq mi) of PSDM data focused on the high-pressure/high-temperature area of the Central Graben.

Theexisting conventional north/south long-offset data will be reprocessed with a deghosting technique to produce an extended-bandwidth dataset as a complement to the growing BroadSeis broadband east/west coverage.

CGG’s next-generation multi-layer tomography, TomoML, will be used to deliver a high-quality PSDM product. TomoML will incorporate CGG’s latest 3D tomographic shallow channel inversion which CGG says is producing excellent results in this area.
