Carbon capture utilization and storage (CCUS) presents the role of carbon dioxide injection, both for enhanced oil recovery (EOR) and storage, in the move toward sustainability. The recent rule establishing a new class (VI) of injection wells, as well as a number of policy and tax incentives in the U.S., have created renewed interest and activity around CCUS technology. This lesson covers general history and specifics of Class VI wells, the role of EOR in storage, misconceptions about carbon dioxide, protections for drinking water resources, and Class VI well considerations, such as storage capacity, injection rate and storage mechanisms.
