CGG extends northern Viking Graben Dual-Azimuth multi-client survey

CGG 9 MarchCGG has announced the phase two of its multi-client 3D survey in the Northern North Sea, which is expected to expand on the phase one acquisition initiated in 2020 to add a second azimuth over CGG’s existing Northern Viking Graben (NVG) multi-client 3D survey and extend coverage into the UKCS

The survey is supported by industry pre-funding.

Commencing in early May and continuing throughout the North Sea season, the 2021 phase two acquisition will add approximately 8,000 sq km of new data in an E-W direction. Similar to the 2020 phase one, multi-component technology will be used for the acquisition, and this new data will be processed together with the existing N-S data, using CGG’s latest velocity modeling and imaging technology, to produce a dual-azimuth volume

As already confirmed by initial results from the 2020 phase one acquisition, the added azimuth is set to enable CGG’s advanced proprietary processing to address and improve the imaging of the multi-directional fault patterns prevalent in the region. Improved resolution will help resolve complex and marginal reservoir stratigraphy. 

Fast-track data from the phase two acquisition are expected to be available by the end of 2021, and final processed data during the second half of 2022.

Sophie Zurquiyah, CEO of CGG, said, “With phase two of our planned multi-year project, CGG continues to follow its strategic path of expanding and enhancing its data library in mature and prolific hydrocarbon regions.”

Zurquiyah further added, “This expansion draws on CGG’s extensive understanding of the Northern Viking Graben and builds on our 44,000 sq km of existing coverage in the Northern North Sea. Early results from the 2020 phase one acquisition demonstrate that, with CGG’s superior imaging, the new data will further de-risk existing fields and unlock the significant remaining near-field potential.”
