eHR-220 HampsonRussell AVO Virtual Workshop

Audience

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

 Content

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 
  • 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
  • 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

 Duration

2-day

 Prerequisites

A basic understanding of geophysics - such as knowing the difference between post-stack and pre-stack seismic data, what a wavelet is etc.

 Software Covered

AFI (AVO Fluid Inversion) is not covered in this course.

 Course Format

Virtual Class Training delivered via GoToTraining.
