Course content

P- and S-waves in isotropic and anisotropic rocks. Principles for the measurement of acoustic properties in the laboratory. Simple rock physics models, mainly based on the Biot-Gassmann poro-elastic theory and critical porosity. Observed and modelled relations between seismic velocities and porosity, lithology, fluid saturation and mechanical stress/pore pressure. Seismic amplitude as a function of offset (AVO) and angle (AVA). Inversion of seismic data. Reservoir monitoring using repeated seismic measurements. Ocean bottom seismics.

Learning outcome

The topic shall give the students an understanding of rock physics and seismic methods used in reservoir geology and reservoir description. The exercises shall make the students able to do quantitative interpretation of seismic data.

Learning methods and activities

Lectures and exercises. The lectures will be held in English if international masterstudents attend. The exam can be changed from written to oral at the postponed exams (continuation exam).
