CGG Delivers First Results from IBALT Stagseis Survey

Source: www.gulfoilandgas.com 9/23/2013, Location: South America

CGG announced that the Fast Trax TTI RTM (Tilted Transverse Isotropy Reverse Time Migration) processed data from its IBALT broadband full-azimuth survey covering over 5,000 km2 (221 blocks) in the Keathley Canyon area of the Gulf of Mexico has been delivered on schedule.

The Fast Trax TTI RTM results from IBALT are the first deliverable in a multi-year, multi-client program that CGG is acquiring in the Gulf of Mexico using StagSeis, its next-generation subsalt imaging solution. StagSeis combines all the recent advances in marine acquisition to acquire full-azimuth, ultra-long-offset and broad bandwidth data to achieve innovative illumination in the most challenging areas, where conventional wide-azimuth acquisition fails to image targets below complex overburdens.

A comparison between a portion of the IBALT survey overlapping CGG’s previous Garden Banks wide-azimuth dataset shows that the Fast Trax TTI RTM imaging results deliver better illumination and improved low-frequency penetration to provide enhanced interpretability of subsalt targets. Final fully processed products will be available in August 2014.

CGG is currently acquiring its second StagSeis survey, 'Deux', which covers 357 blocks adjacent to IBALT. Acquisition of Deux is scheduled for completion in November of this year, with Fast Trax data being available in May 2014 and final data in May 2015.

Jean-Georges Malcor, CEO, CGG, said: "The significantly better subsalt images we are seeing from our IBALT Fast Trax TTI RTM results totally validate our design of StagSeis to meet our clients’ need for a new generation of offshore acquisition solutions to reduce E&P risk. We plan to build on the success of IBALT and Deux to offer this technology in other challenging areas of the Gulf of Mexico."
