Provided by HOT Engineering
This is an intensive, applied course in enhanced oil recovery (EOR). The three main EOR processes covered are miscible flood (CO2 and miscible gas injection), chemical flood (micellar/ polymer), and thermal recovery (steam injection and in-situ combustion). The physics of each EOR process will be covered in detail, including the fundamentals of reservoir fluid flow and recovery mechanisms. Each EOR process will be illustrated with an actual field example. Exercises in class will be conducted to estimate oil production forecasts with EOR.
