Course content

P- and S-wave propagation in isotropic and anisotropic rocks. Principles for the measurement of acoustic properties in the laboratory. Basic rock physics models, mainly based on the Biot-Gassmann poro-elastic theory, effective media theory and critical porosity. Observed and modelled rock physics relations between seismic velocities and porosity, lithology, fluid saturation and mechanical stress/pore pressure. Among the geophysical techniques are the theory and practice of seismic amplitude analysis versus source and receiver offset (AVO/AVA) and seismic inversion. The correlation between well measurements and seismic measurements. The theory and practice of subsurface monitoring using repeated (4-D) geophysical field data measurements through calendar time and principle of seabed seismic (4 Component sensor seismic (4-C)). Combining basic rock physics theory and 4D seismic attributes to illuminate surveillance potential as part of the subsurface Carbon Capture and Storage (CCS) technology aimed at reducing man made CO2 emissions.

Learning outcome

Students shall develop knowledge and skills within quantitative seismic analysis after finishing the course.

Knowledge: At the end of the course, students should understand the theory of rock physics models and the relations between seismic parameters and rock porosity, mineral composition and fluid properties, and in addition how external stress, pore pressure and temperature affect these parameters. They are expected to understand basic methods for estimating reflection coefficients from seismic data, their range of validity and possible sources of error. Students should know how seismic amplitude response can be used to calculate seismic parameters and rock parameters, in addition to hydrocarbon indicators. They shall know the principles and the application of various types of seismic data (2-D, 3-D, 4-D and 4-C seismic), for solving subsurface challenges at hand.

Skills: The students should be able to evaluate and apply rock physics models to analyze and predict seismic parameters and seismic reflection responses when i.e. CO2 is injected into the subsurface. They should also be able to choose and apply relevant seismic analysis schemes by use of software designed for AVO analysis and inversion of seismic data. The students are expected to implement basic rock physics and seismic models through programming applied towards CCS analysis and comparison with real 4D seismic measurements.

Learning methods and activities

Lectures and compulsory exercises in addition to a data lab exercise usage of software combining well and seismic data analysis. The lectures will be held in English if international students attend. The course evaluation is done by a student reference group.

Compulsory assignments

  • Exercises

Further on evaluation

If the teaching is given in English, the examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments. If there is a re-sit examination, the form of assessment may be changed from written to oral examination.

Specific conditions

Compulsory activities from previous semester may be approved by the department.

Required previous knowledge

Students are expect to have basic programming skills in Python, Matlab and/or C++ etc.

Course materials

Books, compendiums and articles from books and journals.

Recommended book: Seismic Amplitude: An interpreter's Handbook, by Rob Simm and Mike Bacon, Cambridge University Press.
