HampsonRussell AVO Workshop

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

Learning Objectives

  • Explains the Rock Physics framework for the study of the AVO method
  • Provides a comprehensive look at the theory and application of the AVO method, a method of increasing interest to explorationists
  • Introduces AVO Inversion methods: Simultaneous Inversion, LMR and EI
  • Emphasizes practical AVO examples from several 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
  • At the end of the course, participants will be able to identify potential AVO applications in their exploration areas and undertake AVO projects

Audience

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


Content

Topics covered in this course include:

  • Introduction: Basic seismic wave principles, Poisson's ratio, gas saturation, Biot-Gassmann equations, and lithologic examples
  • AVO Theory: Zoeppritz equations, Aki-Richards and Shuey's approximation, elastic wave modeling, and impact of anisotropy
  • AVO Analysis: AVO attribute volume generation and considerations, processing concerns, interpretation of AVO measurements, classification of AVO responses, AVO cross plotting and polarization, and examples from published case studies
  • AVO Inversion: Simultaneous pre-stack inversion, Lambda-Mu-Rho, and elastic impedance

Duration: 2 days  Software used: HampsonRussell AVO & AFI (AVO Fluid Inversion) is not officially part of the course but may be covered if time allows

Course Format: Instructor-led, workflow-based, in-person classroom or virtual Prerequisites: 

Experience with HampsonRussell Software is not a prerequisite for this workshop, although students will become familiar with the functionality through attendance.
