    Flow Assurance for CO2 Transportation - Injection System Design and Operation (CCS /CCUS Academy)

    This course covers the key concept, workflow, best practices, and hands-on experience for flow assurance (FA) study in the CO2 pipeline transportation and well injection of CCS/CCUS projects. The course content focuses on the essential flow assurance fundamentals and assessment for a CO2 transportation-injection system during normal and transient operations over its system life. The assessment provides vital inputs for the optimum design and operation of this kind of systems.


    The course content is designed to take the attendees through the typical development workflow and phases of a CO2 transportation-injection system. Every session covers a lecture followed by some hands-on assignments for CO2 transportation-injection system design. The project is based on actual data, where each session and the respective design tasks continue from the previous session.


    At the end of this course, the attendees should understand the essential flow assurance fundamentals, workflow and best practices for a CO2 transportation-injection system design and operation. The attendees should be able to perform the essential flow assurance assessment and provide the respective inputs for optimum design and operation of CO2 transportation-injection systems.


    Note: This course is part of the SLB-CCS/CCUS Academy which has been created to fast track the development of the technical understanding and hands-on skills of petrol technical, flow assurance, process and facility engineers, and other technical engineers involved in CCS/CCUS projects.
