In honor of the new millennium (Y2K), the SEG Research Committee is inviting a series of review articles and tutorials that summarize the state-of-the-art in various areas of exploration geophysics. Further invited contributions will appear during the next year or two—Sven Treitel, Chairman, SEG Research Subcommittee on Y2K Tutorials and Review Articles.
Seismic modeling is one of the cornerstones of geophysical data processing. We give an overview of the most common modeling methods in use today: direct methods, integral-equation methods, and asymptotic methods. We also discuss numerical implementation aspects and present a few representative modeling examples for the different methods.
