Editor's Notes
What is a good reservoir model? -predicts the future (economical purpose) -allows to develop strategies to enhance recovery To build a good model: -integrate all available data: -If static or dynamic not integrated, predictivity will be poor. -for sub seismic faults, integrate all available statistical properties
