NETL supports a number of small-scale field projects which explore and characterize CO2 storage opportunities in North America. The small-scale field projects are designed to demonstrate that regional storage formations have the capability to store CO2 and provide the foundation for larger volume, commercial-scale projects. The field projects are focused on developing a better understanding of different types of geologic storage reservoir classes, thus providing insight into how these depositional systems are capable of influencing the fluid flowing within them. These storage reservoirs may contain natural gas, oil, or saline water–any of which may impact CO2 storage. Read more about small-scale field projects.
Small-scale project data provides valuable information regarding specific formations that have not yet been evaluated for CO2 storage. Small-scale projects focus on the following research objectives:
- Confirm storage resources and injectivity estimates for target reservoirs.
- Validate the effectiveness of simulation models and MVA technologies to predict and measure CO2 movement in the geologic formations and confirm the integrity of the seals.
- Develop guidelines for well completion, operations, and abandonment in order to maximize CO2 storage potential and mitigate release.
- Satisfy the regulatory requirements for small-scale CCS projects.
- Gather field data to improve estimates for storage capacity that could be used to update regional and national storage resource and capacity estimates.
Understanding the impacts of different depositional systems on flow, injectivity, containment, and capacity are critical to both first mover and broad deployment CCS projects throughout the United States. This can only be accomplished by testing and monitoring CO2 in field projects, which help to validate simulation models and determine the effectiveness of the technologies needed to monitor CO2 in the storage formations.
The need to further understand CO2 behavior in various formations and depositional environments has resulted in additional Carbon Storage Program research to support the following small-scale field projects provided on the map below:

In addition to the small-scale field tests described above, NETL is supporting the Weyburn-Midale CO2 Monitoring and Storage Project. The project is an international collaboration which brings together Canada, the United States, the European Community, and Japan, as well as numerous other industrial and government sponsors. The research initiative integrates large-scale commercial enhanced oil recovery (EOR) with carbon storage operations at the Weyburn and Midale oil fields in the Williston Basin, Saskatchewan, Canada. Read more about the Weyburn-Midale CO2 Monitoring and Storage Project.
The project started in September of 2000, in which CO2 has been transported from the Great Plains Synfuel Plant in North Dakota through a 315 mile pipeline and injected into the Weyburn and Midale oilfields. A substantial monitoring initiative has been designed to address both the long-term fate and the security of CO2 storage in geologic formations as part of this project. NETL has supported the site characterization, wellbore integrity assessment, storage monitoring, and risk assessment components of this project. The results of these research initiatives were integrated into a Best Practice Manual for CO2 EOR and storage.
