• The participant will have the complete workflow for various Wavelet Determination, Velocity Modeling & Depth Conversion techniques.

This course is designed for all Oil industry Technical Professionals, which will cover from fundamental theoretical background to high-level real work information/techniques/workshop.

This training course is suitable to a wide range of professionals but will greatly benefit:

• Seismic Interpreters.
• Geophysicists
• Geologists
• Geo-Modelers
• Petrophysicists
• Drilling Engineers
• Reservoir Engineers
• Technical Support Personnel
• Team Leaders
• Managers

The course will not only be presented by showing and interpreting the material in detail, but also the participants will work together using a real Seismic data to apply all the workflow and to project their previous knowledge and experience onto the course, they also encouraged to bring their own data so that real working examples can be reviewed and interpreted.
