ProAZ Azimuthal Attributes Workshop
November 9th, 2023, from 9AM to 5PM
Online (Central Time), Houston Texas
Learning Objectives
This course covers the theory and practical use of ProAZ, an interactive program that that is fully linked within HampsonRussell Software and performs Azimuthal AVO analysis and fracture analysis.
Audience
Geophysicists, geologists, engineers and technical staff who want to understand the theory and learn how to apply these increasingly critical techniques. Experience with HampsonRussell Software is NOT a prerequisite for this workshop, although students will become familiar with the functionality through attendance
Content
- Introduction: Basic seismic wave principles, anisotropy, the relationship between fractures and anisotropy, observing anisotropy in prestack seismic data, Common Offset / Common Azimuth (COCA) Gathers
- AVAZ Modeling: Fractured rock physics, building an anisotropic model, and azimuthal convolutional modeling
- AVAZ Theory: Anisotropic Zoeppritz's equations and approximations and the impact of fractures
- AVAZ Analysis: AVAZ attribute volume generation and considerations, processing concerns, interpretation of AVAZ measurements and examples from published case studies ̶ both the Rüger equation and Azimuthal Fourier coefficients will be discussed
- VVAZ Theory and Analysis: Azimuthal NMO and RMS velocities, azimuthal NMO corrections, inverting for interval properties using the generalized Dix equation, and examples from published case studies
Course benefits include:
-
-
- Explains the Rock Physics framework linking fractures and anisotropy for the study of the Amplitude versus Azimuth (AVAZ) and Velocity versus Azimuth (VVAZ)
- Provides a comprehensive look at the theory and application of the AVAZ method, a method of increasing interest with the growing importance for unconventional and fractured reservoirs
- Discussion on the similarities and differences between AVAZ and VVAZ attributes
- Emphasizes practical AVAZ and VVAZ examples from a number of regions around North America
- Explains both the advantages and potential pitfalls of the AVAZ method
- Consists of both lectures and hands-on exercises, using the ProAZ software. The exercises comprise approximately one third of the course
- At the end of the course participants will be able to identify potential AVAZ applications in their own
