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. The theory and practice of seismic amplitude analysis versus source and receiver distance (AVO/AVA) and seismic inversion. The correlation between well measurements and seismic measurements. The theory and practice of subsurface monitoring using repeated (4-D) seismic data through calendar time and seabed seismic (4 Component sensor seismic (4-C)).

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 should also understand basic methods for estimating reflection coefficients from seismic data, their range of validity and possible sources of error. Students shall also know how seismic amplitude response can be used to calculate seismic parameters, rock parameters and 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. 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 elements of rock physics and seismic models through programming for further analysis and comparison with well and seismic data.

Learning methods and activities

Lectures and compulsory exercises in addition to an exercise in the data lab through usage of software for well and seismic analysis. The lectures will be held in English if international students attend. Course evaluation is by 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 or 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.
