Principles Aspects of Enhanced Oil Recovery

The course key learning objective is for the participants to obtain fundamental knowledge of EOR methods. The course covers the economic feasibility and risks of EOR projects, regulatory and environmental aspects, and strategies for optimizing production and extending reservoir life. Attendees will also acquire knowledge on EOR project design, planning, and implementation, including pilot tests and field-scale development, and will understand the collaborative roles of various disciplines in successful EOR field development. Overall, participants will leave equipped with both theoretical knowledge and practical skills relevant to real-world EOR applications.

Introduction to hydrocarbon recovery

• Understanding the subsurface
• The genesis and physical properties of hydrocarbons and water
• Oil and gas production
• How much oil or gas is usually recovered
• Exercise 01: Gas recovery estimation

Objectives of Enhanced Oil Recovery (EOR)

• The different modes of oil recovery
• Applicability of different EOR methods
• Key components of the following EOR methods
• Condensate stripping
• Flue-gas soaking
• Miscible gas flooding (including mWAG)
• Thermal methods
• CO2 flooding
