Carbon Capture and Storage (CCS) Well Design and Operations
In this 3-days course equips participants with the knowledge and skills for designing, operating, and managing wells used in underground storage of carbon dioxide (CO2). By the end of this course, participants will be able to apply their knowledge to design, operate, and manage wells for CO2 storage projects, evaluate the feasibility of CO2 storage sites, identify and mitigate risks associated with CCS operation and communicate effectively about CCS technology.
