AVO and Seismic Inversion

Book now button

Course Objectives

To describe the processes of AVO (Amplitude vs Offset), and Seismic Inversion, emphasizing on the techniques for obtaining acoustic impedance and "elastic" impedances from the amplitudes of the reflection seismic traces, as well as giving an introduction of those based on the use of attributes of the seismic trace for the estimation of rock parameters.

The course is designed for

Geophysicists, geologists and reservoir engineers with some basic knowledge of the seismic reflection method.
