Climate change is a major challenge. Secure, reliable and affordable energy supplies are needed for economic growth, but increases in the associated carbon dioxide (CO2) emissions are the cause of major concern. Carbon dioxide Capture and Sequestration (CCS) in deep geological formations is a promising technology to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. In this paper, the procedures and related principles will be introduced, and the advantages and disadvantages will also be discussed. Keywords: CCS, Carbon dioxide, Geological sequestrations, Well integrity
