Introduction to Geophysics: Seismic Acquisition, Processing And Interpretation
This four-day course is designed to provide an introduction to young E&P professionals to the key concepts and principles of geophysical applications in exploration, field appraisal, and reservoir management. Emphasis is on practical understanding of seismic acquisition, processing, imaging, interpretation and prediction of geological and petrophysical properties from seismic. Pitfalls and practical issues of geophysical data in E&P workflows are discussed. Data examples, videos,and exercises, are used to illustrate key concepts. The practical aspects of seismic interpretation for prospect maturation are covered with examples that involve structural and stratigraphy mapping, attribute analysis and quantitative interpretation.
