Miscible Gas Injection and WAG Fundamentals

This 5 days training course introduces the  fundamental principles of Enhanced Oil Recovery  processes. The participants are exposed to  technologies associated with Miscible processes. Basic EOR screening criteria, fundamental science  behind EOR applications will also be discussed.
Miscibility concepts and PVTi usage on EOS calibration for Miscible EOR simulation will be discussed. The compositional simulation will be introduced and used for modeling Miscibility and simulation of WAG process.
