      • Average client rating (based on 180 attendee reviews)

    The overall objective of the course is to introduce E&P professionals to the key concepts and principles that form the basis for value added geophysical applications in exploration, field appraisal, and reservoir management.  Learning objectives are at basic awareness to knowledge levels.  Emphasis is on practical understanding of seismic acquisition, processing, imaging, interpretation and prediction of geological and petrophysical properties from seismic.  Data examples, videos, exercises, and workshops are used to illustrate key concepts.  Practical issues, and pitfalls as they affect the application of geophysical data and information in E&P workflows are discussed.  The practical aspects of seismic interpretation are covered with examples that involve seismic structural mapping, stratigraphic analysis, and amplitude/attribute methods.

    This course is also available in a 5-day version using challenges from the OilSim Simulator
