StagSeis
Reduce risk for offshore subsalt prospects with improved seismic image quality, clarity and detail
StagSeis™ seismic technology from CGG addresses the most challenging areas where conventional wide azimuth acquisition fails to illuminate targets below complex salt. It includes a patented acquisition design (staggered vessel configuration) with very long offsets (up to 18 kilometers) and full azimuth coverage (up to nine kilometers) for improved illumination.
Benefits
- Enhanced broadband imaging for subsalt targets obscured by complex overburdens with excellent penetration from low frequencies, and full-azimuth illumination
- More detailed and accurate velocity models with very long offsets and leading CGG TLFWI technology
- Clearer images with natural full-azimuth multiple attenuation
- Addresses anisotropy in complex environments with CGG’s Tilted Orthorhombic (TOR) modeling and imaging
Associated Data Sets
Three StagSeis surveys have been performed in the Gulf of Mexico in some of the most challenging salt tectonic environments to provide enhanced imaging. This data is currently being reimaged with the latest technology, including TL-FWI:
