Enhanced Oil Recovery (EOR)

Course description

This course is designed for post-graduate (MSc and PhD) students. The main syllabus of this course are:

1. Introduction to EOR process (Definition, classifications and screening criteria)
2. Modelling of water flowing, polymer and chemical flooding using fractional flow theory
3. Macroscopic displacement (Volumetric, areal and vertical sweep efficiency, mobility ratio)
4. Mobility control process including WAG (water alternating gas) injection, foam flooding, polymer injection. The critical issues as well as modelling are discussed.
5. Chemical flooding: phase behavior of oil-water emulsion, chemical adsorption on rock, modelling of chemical flooding.
6. Miscible flooding: phase behavior and ternary diagram, first contact and multi-contact miscibility, dispersion and mixing during miscible flooding, minimum miscibility pressure (MMP), Todd-Longstaff method for modelling of miscible flooding
