Final results from IBALT and DEUX, the first and second surveys of CGG’s StagSeis™ multi-client program of 871 offshore blocks in select locations of Garden Banks, Keathley Canyon, Walker Ridge and Green Canyon, are now available and widely recognized as the clearest subsalt images in this complex area of the Gulf of Mexico. Final results from the third survey, TROIS, are due next year.

The original IBALT survey commenced acquisition in 2012 but planning began three years earlier. At the time, wide-azimuth (WAZ) surveys with advanced processing techniques provided the best subsurface images in the Gulf of Mexico, but some features below more complex salt structures remained difficult to illuminate and image fully.
