Summary | The course introduces the seismic reflection method, including land and marine data acquisition and processing, with emphasis on the geological interpretation of seismic reflection data. The following topics are covered: the role of the seismic reflection method in exploration; seismic velocities; seismic data acquisition; the seismic wavelet; seismic data processing; structural Interpretation; stratigraphic interpretation; seismic-to-well tie; the seismic report.
Practical exercises include the interpretation of a seismic reflection dataset using Petrel interpretation software.
