StagSeis

StagSeis™ is a 'next-generation' solution for subsalt imaging, designed to reduce exploration and production risk by providing the best seismic images below complex salt. It addresses the most challenging areas where conventional wide azimuth acquisition fails to illuminate targets below complex overburdens. It includes a patented acquisition design (staggered vessel configuration) with very long offsets (up to 20 km) and full azimuth coverage (up to 10 km) for improved illumination.
