CGG Delivers First Results From IBALT StagSeis Survey In Gulf Of Mexico

PARIS, France, Sept. 23, 2013 (GLOBE NEWSWIRE) --
CGG  announced today that the Fast  Trax(TM) TTI RTM (Tilted Transverse IsotropyReverse  Time Migration)  processed data  from its  IBALT broadband full-azimuthsurvey  covering over 50,000 km(2)  (221 blocks) in  the Keathley Canyon area ofthe 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 usingStagSeis(TM),  its next-generation  subsalt imaging  solution. StagSeis combinesall  the recent advances  in marine acquisition  to acquire full-azimuth, ultra-long-offset  and broad bandwidth data to  achieve innovative illumination in themost  challenging areas,  where conventional  wide-azimuth acquisition  fails toimage targets below complex overburdens.A  comparison between a  portion of the  IBALT survey overlapping CGG's previousGarden  Banks  wide-azimuth  dataset  shows  that  the Fast Trax TTI RTM imagingresults  deliver better  illumination and  improved low-frequency penetration toprovide  enhanced  interpretability  of  subsalt  targets. Final fully processedproducts will be available in August 2014.CGG is currently acquiring its second StagSeis survey, "Deux", which covers 357blocks  adjacent to IBALT.   Acquisition of Deux  is scheduled for completion inNovember of this year, with Fast Trax data being available in May 2014 and finaldata in May 2015.Jean-Georges Malcor, CEO, CGG, said: "The significantly better subsalt images weare  seeing from our IBALT Fast Trax TTI RTM results totally validate our designof  StagSeis  to  meet  our  clients'  need  for  a  new  generation of offshoreacquisition  solutions to reduce  E&P risk. We  plan to build  on the success ofIBALT  and Deux to offer this technology  in other challenging areas of the Gulfof Mexico."About CGGCGG ( is a fully integrated Geoscience company providing leadinggeological, geophysical and reservoir capabilities to its broad base ofcustomers primarily from the global oil and gas industry.
