ABOUT COURSE

COURSE DESCRIPTION

This five-day course provides clear and concise information on reservoir engineering and reflects advances in enhanced oil recovery. The course will help engineers understand, simulate and practice the major enhanced oil recovery techniques. The course involves seven projects that are designed to allow practice of the oil recovery techniques using analytical, statistical and numerical simulation models. The numerical approaches are using CMG fluid models IMEX (three-phase black oil simulator), GEM (equation-of-state compositional simulator), and STARS (three-phase multi-component thermal simulator).
