"Rock Physics Templates in AI-GI and Extended Elastic Impedance Domains"

Dr. Juan-Mauricio Florez, BHP Billiton Petroleum, Houston, TX


Rock physics templates (RPT) in both AI-GI and extended elastic impedance (EEI) domains as a framework for modeling, constraining and interpreting both band-limited and model-based AVO inversion results. We briefly review the concept of gradient impedance (or impedance gradient) as an AVO attribute linked to the concept of elastic impedance (EI). We outline the process of building RPT for end-member lithologies in AI-Vp/Vs domain as a preliminary step to build RPT in AI-GI and EEI domains. Finally, we explain the use of rock physics templates and trends to constrain AVO inversion and as a tool for interpretation of inversion results, evaluating variations in fluid, lithology and porosity.
