Seismic depth imaging
Integrated imaging – Why ?
• Integrate seismic with alternative geophysical techniques to build the most accurate near sub-surface model characterized by a high level of spatial resolution at low cost
• Exploit recent breakthroughs in non-seismic technologies
• Enhance depth imaging & reduce risk
