Fault Seal Analysis
Candidates:
Exploration and production geoscientists, and reservoir engineers
Summary:
The course aims to give an idea on new methods for evaluating sealing faults. The emphasis is placed on the application of an objective methodology to the analysis of subsurface data (seismic interpretation & wells).
