Three-dimensional Poststack Migration
This work presents cutting-edge three-dimensional numerical methods capable of handling seismic data computations at frequencies of at least 0.5 Hz, specifically for very large teleseismic epicentral distances. It outlines a comprehensive framework for 3D migration methods, with short-term goals focusing on standardized analytic (GRT, FK, WKB) and numerical (FD, Spectral) methods. Long-term objectives include developing modules for various numerical algorithms, facilitating hybrid method advancements, and creating models and synthetic datasets to benchmark new techniques, utilizing the 2DSEG-EAGE salt model.

Computational tools • 3D numerical methods that can handle calculations up to a frequency of at least 0.5 Hz for large (very large! teleseismic) epicentral distances. • 3D migration methods.
Suggestions on CIG goals • Short-term: standardized current analytic (GRT, FK, WKB) and numerical methods (FD, Spectral). • Long-term: Modules for numerical algorithms – would allow developments of various hybrid methods. Modules for some standardized algorithms in migration. Models and synthetic sets that would allow benchmark of new methods.
