Basic Seismic Interpretation

Who should attend:

Exploration and production geophysicists, exploration geoscientists.

Overview:

This course assumes a basic knowledge of seismic interpretation and concentrates on the role of the seismic interpreter in the search for oil and gas. In addition to workshop exercises focused on the traditional mapping of subsurface structures, we also look at direct indicators of hydrocarbons using techniques such as AVO and Seismic Inversion. The focus is on real hands-on exercises, which should reinforce the contents of the course.
