De-risk offshore subsalt prospects, better evaluate opportunities, and gain confidence in appraisal wells. CGG’s StagSeis™ shows staggering improvements in subsalt image quality, clarity and detail for better definition of faults and geohazards. Ultra-long offset, full-azimuth, broadband survey provides enhanced geological definition of subsurface, from overburden to previously obscured subsalt reservoirs.
