Reservoir characterization using seismic inversion (prestack-postack), and post Stack attributes
Overview
The course will present in simple terms the principles of the different techniques and types of inversion while pointing out their respective merits and limitations. This will be illustrated with examples and a practical demonstration of some of the inversion techniques will be given so an understanding of the sensitivities of some of the scemes can be shown
Learning, methods and tools:
At the end of the course participants will understand basic concepts in quantitative seismic analysis and interpretation based on AVO, well-to-seismic calibration and inversion techniques. Participants will consolidate their understanding of modern technology with recent field study examples and practical workshop exercises.
