Subsurface CO2 Sequestration (RES73)


    This course will develop your understanding of the fundamentals of subsurface CO2 sequestration or CO2 storage in saline aquifers, depleted or producing hydrocarbon reservoirs and methane coalbed seams.
    It provides you with scientific principles and mathematical tools to help in the design and selection of subsurface CO2 sequestration projects as a proposed technical solution to reducing the concentration of CO2 in the atmosphere by injecting it underground.

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

    Designed for you, if you are...

    • A reservoir engineer working in CO2 sequestration EOR projects

    How we build your confidence

    This course builds a firm knowledge foundation by combining theory lectures with practical examples and case studies.
