This course deals with the analysis and application of the acoustic and elastic wave equations in exploration seismology. In particular, the course focuses on the finite-difference modeling of the full wave equation and its application to forward modeling and migration.
Duration
Two days
Intended Audience
Entry level to Intermediate
Prerequisites (Knowledge/Experience/Education Required)
The course will show many examples for the seismic modeling and migration some with animations. The addition of elastic modeling and migration will require presenting the standard material on elastic waves. Students today should be comfortable with these ideas.
