Chemical EOR

• • Brief overview of different EOR methods for light and heavy oil.
    • Review of fundamental principles of displacement and phase behavior needed to understand chemical EOR methods. 
    • Cover four major types of chemical EOR, specific chemicals in each category, conditions under which they work, and special problems encountered with each.
    • Review of phase behavior and fluid property modeling.
