Course Description

The main objective of this course is to provide an opportunity to develop hands-on experience of various Seismic Interpretation techniques using the PETREL software package. The course will cover the essential Geological and Geophysical information necessary to visualize and interpret seismic data. The participants will gain a solid understanding of the applications and role of the seismic interpreter in studies.

A significant percentage of the course is dedicated to reinforcement and advancement of interpretation techniques using practical exercises – both on the PETREL software and by hand. This will guide the participants in the understanding that the integration of all available data into the seismic model will add value in the needed coherent and successful seismic predictions that result from an interpretation.
