Summary
This course provides clear, concise and practical information for understanding, simulating and implementing carbon dioxide recovery projects. Case studies are used to demonstrate a variety of evaluation and predictive techniques using experimental, analytical and numerical methods. Operational aspects including transportation, injection, separation, reinjection and corrosion are discussed.
Duration and Training Method
A three-day classroom course, with time equally divided among lectures, case studies and computer-based practical exercises.
Participants will learn to:
- Judge the technical reasons for the recent increase in gas injection operations in the US.
- Implement EOR screening.
- Assess the merits of lean-gas and enriched-gas injection operations.
- Characterize the nature of miscible and immiscible flooding.
- Select laboratory tests and screening for pilot design.
- Assess minimum miscibility and injection pressure of a CO2 injection operation.
- Predict the effects of hydrodynamic instabilities on the oil displacement front.
- Estimate recovery efficiency of a CO2 injection using analytical viscous fingering models.
- Create a compositional equation of state model for simulation of CO2 injection.
- Optimize a CO2 injection operation using simulations.
- Evaluate and address operational aspects of CO2 projects.
The course will help engineers understand, simulate and practice the major enhanced oil recovery techniques. The course involves projects that are designed to practice the oil recovery techniques using analytical, statistical and numerical simulation models. The numerical approaches are using CMG GEM (equation-of-state compositional simulator), and STARS (three-phase multi-component thermal simulator).
