HR-220 AVO Workshop


Geophysicists, geologists, engineers and technical staff who want to understand the theory and learn how to apply these increasingly critical techniques.


This course covers the theory and practical use of AVO, an interactive program that is fully linked within HampsonRussell software and performs Amplitude versus Offset modeling and analysis.

Topics covered include:
- Introduction: Basic seismic wave principles, Poisson’s ratio, gas saturation, Biot-Gassmann equations, and lithologic examples
- AVO Theory: Zoeppritz’s equations, Aki-Richards and Shuey’s approximation, elastic wave modeling, and impact of anistropy
- AVO Analysis: AVO attributes, processing concerns, interpretation of AVO measurements, AVO crossplotting and polarization, AVO Inversion: Simultaneous pre-stack inversion, Lambda-Mu-Rho, and elastic impedance

Learning Objectives

- Explains the Rock Physics framework for the study of the AVO method
- Introduces AVO Inversion methods: Simultaneous Inversion, LMR and EI
- Emphasizes practical AVO examples from a number of regions around the world
- Explains both the advantages and potential pitfalls of the AVO method
- Consists of both lectures and hands-on exercises, using the AVO software. The exercises comprise approximately 65% of the course
