Course Description

This course follows on from the foundation built in the poststack course and deals with the prestack nature of migration and its superior capability of imaging the subsurface. Basic methods of migration are presented in a simple manner and use diagrams and figures to illustrate principles. The concepts are presented in an intuitive graphical manner without detailed mathematics that can obscure the fundamental concepts. Some mathematics is included to illustrate the simplicity of the algorithms. Numerous geometrical constructions are included in the notes to illustrate the simplicity of migration algorithms. Laboratory exercises will evaluate modelling and migration programs.

Course Details

Course Details:

1. Prestack modelling with variable source receiver offsets is studied along with some prestack models.
2. Dip moveout is evaluated, especially the conditions under which it is a useful process.
3. Prestack algorithms of source (shot) records and constant offset section are compared with other prestack algorithms.

Who Should Attend:  The course is designed for all geophysicists, independent of their background. Each participant will have an understanding of the basic algorithms and should be able to communicate freely between processing specialists and seismic interpreters. Those with computer skills will be able to write their own migration programs.
