CIPR University of Bergen
2
Background
- Predict reservoir flows
Physical/Numerical model
Property model
Calibrated property model
Calibrated permeability model
3
Work Flow - Alternatives
Need good initial guess
- CPU intensive
Insufficient information
Selection of zones?
Finer scale variations?
4
Selection of Zones Multiscale Estimation
Ordinary ME
Reference permeability
Adaptive ME
5
AME Some Examples
