Participants will learn to:

1. Design a core analysis programme to supply all data required for reservoir modelling.
2. Perform quality checking of core analysis data.
3. Build a saturation height function for use within the reservoir model.
4. Measure and quality check relative permeability data, and integrate these data into the reservoir model.
