Prestack Seismic Data Analysis

Intermediate |  4 half days  |  Online  |  Hands-on

The Prestack Seismic Data Analysis course covers quantitative interpretation (QI) and practical amplitude analysis. Prestack data analysis using the Sharp Reflections Big Data platform unlocks all collected trace data. You learn how to analyze and interpret your prospects and reservoirs more quantitatively; confidently predicting lithology and fluid-fill. Using the platform’s toolkits, you will gather a unique insight to data quality, with the capability to process and condition seismic for detailed attribute analysis that you will never extract from a stack volume.

In this online hands-on course, you will work with a dataset from the Johan Sverdrup field.

  • 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
