Advanced Deterministic Pre-Stack Inversion with RockTrace

Learning Objectives

• Acquire the ability to perform Simultaneous Inversion projects with basic settings and QC analysis. Through practice and experience, you will be able to understand and take full advantage of RockTrace's functionalities and capabilities.

Audience

This training course is intended for people who have experience with acoustic impedance inversion projects and need to learn more about simultaneous inversion.

Content

Seismic data responds to both the acoustic impedance and the shear impedance contrasts in the subsurface. This additional information within the seismic data can be exploited using the variation in seismic reflection amplitude with angle or offset.

Jason’s Simultaneous Inversion overcomes most of the disadvantages of standard AVO analysis and integrates the best of inversion while exploiting the full information within the seismic data. RockTrace is the module within the Jason Workbench that performs simultaneous inversion. RockTrace builds on Jason’s InverTracePlus full-stack inversion technology by extending it to the AVO domain.

The result is three volumes of absolute rock properties tightly calibrated to the well log data: P-impedance, S[1]impedance, and Density. These results are most used to delineate lithology, porosity, fluid content and other petrophysical parameters. This course will teach the participants to independently run the RockTrace Simultaneous Inversion software, QC, and interpret and analyze the results.
