    CO2 Static Containment Evaluation (CCS/CCUS Academy)

    This course covers the key concept, the best practices, and the hands-on competence in caprock integrity and fault seal evaluation for CCS/CCUS projects from a geological perspective. The course comprises two main technical topics: cap rack integrity and fault seal evaluation. This course aims to introduce the workflow and best practices for conducting caprock integrity and fault seal evaluation and storage capacity evaluation for CCS/CCUS projects. The course uses a real CCUS project dataset, and a major portion of the course will be hands-on Petrel exercises that cover the key technical steps of interpretation, model building, evaluation, and analysis.

    At the end of this course, the attendees should develop the competence to evaluate caprock integrity and fault seal for actual CCS/CCUS projects.

    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 petrotechnical engineers, processing engineers, facility engineers, and other technical engineers involve in CCS/CCUS projects.
