EOR: Miscible Gas Injection (RES47)


    This course will develop your understanding of the fundamentals of enhanced oil recovery, the applications of scientific principles to reservoir fluid phase behaviour and multiphase fluid flow in porous media. It provides you with mathematical tools to help in the design and selection of gas injection EOR projects.

    Course Level: Advanced
    Duration: 5 days
    Instructor: Edmond Shtepani
