Course content

Elastic waves. Basics of theory of elasticity. Wave equation and eikonal equation. Amplitudes and traveltimes. Converted waves, multiple reflected waves, diffracted waves, head waves and diving waves. Attenuation and velocity dispersion. Homogeneous and heterogeneous models. Multi-layered models. Reflection and transmission at interface. Anisotropic models and anisotropy parameters. Theory of effective medium. Basics of seismic data processing and seismic imaging.

Learning outcome

Ingress: This course will provide an overview and a theoretical understanding of how seismic waves propagate in the earth, especially with regard to applications of reflection seismic.

Knowledge: Students should understand how seismic waves propagate in a medium and how a seismic acquisition is set up to measure the transmitted waves. In addition, students should have an overview of how seismic processing is performed. Students should understand how seismic data processing and interpretation is related to digitalization and sustainability of society.

Skills: Students should be able to interpret seismic shots and CMP-gathers with respect to different wave types. Students should also have an overview of different theories and concepts used in seismic wave propagation.

General competence: Students should have a basic knowledge in seismic wave propagation as a basis for more advanced courses on the subject.
