Postgraduate Course: Seismic Reflection Interpretation (PGGE11144)

Course Outline
SchoolSchool of Geosciences CollegeCollege of Science and Engineering
Credit level (Normal year taken)SCQF Level 11 (Postgraduate) AvailabilityAvailable to all students
SCQF Credits10 ECTS Credits5
SummaryThe 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.
