Practical Quantitative Interpretation (PQI)

12:02 Hours
Practical Quantitative Interpretation (PQI) is a comprehensive course designed to equip interpreters with a modern approach to seismic data analysis. Unlike traditional seismic processing that stacks traces and loses valuable information, PQI leverages pre-stack seismic data and integrates rock physics to reveal detailed rock properties and classify lithologies. This powerful technique transforms seismic volumes into geological models that improve well planning and production outcomes. The course covers key topics such as seismic attributes, well data analysis, rock physics, classification, and the overall QI workflow. It is structured into fundamentals, intermediate, and advanced levels to progressively build competency in geoscience disciplines.
