HampsonRussell ProAZ Azimuthal Attributes Training
This training course is available upon request. When requesting a course, please know there is a minimum number of participants needed for the course to be held. Request more information in the form to notify our team of your interest.
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.
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
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
Duration: 1 day Software used: HampsonRussell ProAZ Course Format: Instructor-led, workflow-based, in-person classroom or virtual Prerequisites: Experience with HampsonRussell software is NOT a prerequisite for this training course, although students will become familiar with the functionality through attendance of this class.
