HR-235 ProAZ Azimuthal Attributes Workshop

Audience

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

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 Theory and Modeling and: 
  • AVAZ Analysis: AVAZ attribute volume generation and considerations, processing concerns, interpretation of AVAZ measurements and examples from published case studies. 
  • 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.

Learning Objectives

• 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
• 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
