Geophysics for Geologists and Engineers

Instructors: Thomas R. Wittick
Course Length: 5 Days
Course CEUs: 4.0

Course Description
A must seminar for people working with geophysical data and who want to improve their knowledge of geophysical principles and techniques.  This seminar provides a practical understanding of geophysical principles and techniques for geologists, engineers, processing geophysicists, entry level geophysicists and managers that is applicable to their work.  It provides users of seismic data and people who make decisions based on seismic interpretations with the background they need to perform or evaluate geophysical interpretation. The seminar introduces the major interpretive techniques currently in use and shows the types of problems each technique solves as well as the pitfalls associated with each procedure. The workshops throughout the seminar provide participants with experience in using the interpretive techniques.

Participants will gain an understanding of how different types of seismic data acquisition and processing impact the final seismic section or data volume they work with and they will be able to make better interpretive decisions because of that knowledge. Participants will also gain an appreciation for the difference between exploration and exploitation/development geophysics, and acquire practical experience in structural and reservoir interpretation techniques that they can use when they return to their jobs.

Learning Outcomes:

  1. Gain an understanding of how seismic data are acquired, and how different acquisition techniques affect the final data volume
  2. Develop a basic understanding of the various steps used in seismic data processing, and how they affect the final data volume
  3. Develop an understanding of the differences and similarities in the way logging devices and seismic data measure subsurface acoustic properties
  4. Create an appreciation for the value of calibrated seismic data
  5. Gain an understanding of how seismic modeling, seismic trace inversion, AVO and seismic trace attributes are used to find and develop oil and gas fields

Who should attend
Engineers, geologists, geophysicists, geotechnicians, managers, geophysical processors, and landmen wanting to perform and evaluate geophysical interpretations.
