CGGVeritas has begun field operations on the first in a series of planned wide-azimuth data library surveys in the deepwater
The new data library survey is currently the largest wide-azimuth project in the world, covering 464 lease blocks in the prolific Walker Ridge area of the
The SR/V Veritas Viking is recording the wide-azimuth data along with four newly rigged vessels – the Sigma, Bjorkhaug, Tenor and Vardholm – acting as source vessels. Together, they are using an acquisition configuration modified from the industry-first deepwater
This configuration records double the cross-line offset with each sail line compared to previous wide-azimuth surveys while maintaining optimal data quality.
"Our first non-exclusive wide-azimuth survey brings a whole new scale of data acquisition to a highly prospective area of the Gulf of Mexico," said Tim Wells, president,
Using proprietary software specifically designed for wide-azimuth geometry, including multiple removal, tomography, beam migration and wave equation migration, processing of the wide-azimuth data will begin approximately 2 weeks after the first sail line has been recorded, and a Fast-Trax Migration will be ready approximately 2 months after completion of acquisition in early 2008.
