Prestack Quantitative Amplitude Interpretation
Intermediate | 4 half days | Online | Hands-on
The Prestack Quantitative Amplitude Interpretation course covers practical amplitude analysis and quantitative interpretation (QI). Prestack data analysis using Sharp Reflections software unlocks information in postmigration trace data that is obscured in traditional full or partial stacks. You will learn to analyze and interpret your prospect and reservoir seismic data more quantitatively, and to map lithology and fluid-fill away from well calibration more confidently. Using the software’s toolkits, you will gather unique insight into data quality and the limits of interpretability. You’ll also learn to process and condition seismic data to achieve detailed attribute analysis that cannot be extracted from common partial stack volumes.
In this online hands-on course, you will work with a real dataset from the North Sea.

Exploration and production geoscientists, seismic interpreters, QI geophysicists.
- Exploit the value in prestack seismic data
- Understand the principles of seismic Amplitude-Versus-Offset/Angle and its relationship to rock and fluid elastic properties
- Explore and validate seismic responses with forward modelling
- Review the concept of AVO classes and AVO cross-plots
- Understand the uses of seismic AVO attributes, relative impedance attributes, and pre-stack colored inversion data
- Investigate common sources of error in typical quantitative interpretation workflows (QI), and how they can be avoided with pre-stack techniques
- Step into geology with estimates of layer properties
