Entry requirements

180 credits including (1) 80 credits in physics and mathematics or (2) 70 credits in earth science and 45 credits in physics and mathematics. In both cases Continuum Mechanics in Geophysics, 5 credits, and at least 2.5 credits from Introduction to Seismology, 5 credits. Proficiency in English equivalent to the Swedish upper secondary course English 6.

Learning outcomes

On completion of the course, the student should be able to:

• Give an account of the basic principles of reflection and refraction seismic data acquisition and processing.
• Apply Snell's law in solving ray tracing problems.
• Describe how the eikonal equation is used in seismic migration.
• Explain the concepts and apply the different types of migration techniques (Kirchhoff migration, downward continuation, phase shift migration).
• Apply processing steps to seismic data using MATLAB and make changes in the computer code.
• Evaluate models of seismic wave velocities produced by inversion (tomography) of refraction seismic data for ambiguity and equivalence of model structures.

Content

Basics of reflection and refraction seismics, including seismic tomography. Numerical methods for filtering of reflection seismic data. Migration including pre-stack migration, dip moveout (DMO), Radon transforms. Inversion of refraction seismic traveltimes.

Instruction

Lectures, homework, problem solving and computer exercises

Assessment

Written examination (3 credits) and homework assignments (2 credits).

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
