CCS for Reservoir Engineers (RES75)


    Carbon Capture and Geological Storage (CCS) will play a critical role in the portfolio of energy companies to meet climate goals and reach net-zero by 2050. It is seen as one method to mitigate atmospheric CO2 concentrations while using fossil fuels in the energy system. For CCS to become a viable option for carbon reduction strategies, several challenges must be overcome. Among them, the geologic storage of CO2 is a key technology.
    The objective of this course is to discuss and present the required reservoir engineering skills for safe and effective storage of CO2 in the subsurface geologic formations. Focus is given on depleted hydrocarbon fields and deep saline aquifers as these types of underground storage are becoming mature technologies soon.
    The course will cover relevant regulatory frameworks, fluid properties of CO2 and data collection, but the main focus will be on reservoir engineering methods during static and dynamic modelling as well as risk assessment based on the three driving pillars: (a) injectivity, (b) capacity, and (c) containment of carbon dioxide.

    COMPUTER REQUIREMENTS: MS Office (Excel, Word and Powerpoint)
    Participants are welcome to bring their own laptops to class.

    Course Level: Skill
    Duration: 4 days

    Designed for you, if you are...

    • A petroleum engineer or reservoir engineer with some experience in the field and some basic knowledge about CCS

    How we build your confidence

    The theoretical and practical aspects of CO2 injection and storage in the subsurface are discussed in a group setting, along with examples and case histories. You will be encouraged to engage in discussions based on your experience.
    Videos and calculations will strengthen your understanding of the theoretical and operational principles. Working on examples will support the learning experience.
