Advanced Seismic Data Processing
Who should attend:
Geophysicists who are actively involved in advanced or special seismic data processing, especially those who are a member of a multi-disciplinary team.
Overview:
With the new techniques of seismic data acquisition, new processing methods have been developed. Existing and new data sets are exploited for optimal information retrieval. Other data types like well data and geological information should be properly integrated in inversion studies to constrain the results.
This course deals with advanced processing methods that are often carried out as part of a special study, and involves integration of data acquisition, processing and interpretation; as well as petrophysics, petroleum geology and reservoir engineering. The topics that will be discussed cover a wide spectrum and are representative for what has become feasible nowadays.
Content:
The following topics will be discussed:
- Stress-strain relationships
- The wave equation
- Wave-field extrapolation
- Anisotropy
- Migration; time migration, depth migration, true-amplitude migration: theory and algorithms
- DMO (dip move-out) and PSI (pre-stack imaging: theory and algorithms
- Velocity model building and updating: theory and algorithms
- VSP and hole-to-hole seismic: acquisition and processing
- Multi-component seismic, shear seismic and anisotropy: acquisition and processing
- OBC (ocean bottom cable) and OBS (ocean bottom system): acquisition and processing
- Design and assessment of different acquisition geometries
- AVO (amplitude versus offset) and AVA (amplitude versus angle): theory and processing
- Inversion: different methods
- 4D or time-lapse seismic
