Regional Carbon Sequestration Partnerships Validation Phase

Validation Phase

The Regional Carbon Sequestration Partnerships' (RCSP) Validation Phase focuses on evaluating the most promising regional opportunities to deploy carbon capture and storage (CCS) technologies through a number of small-scale field projects (injection of less than 500,000 metric tons of CO2 per year). The Validation Phase field test efforts 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 CO2 storage in different types of geologic depositional environment storage reservoir classes. Understanding these different storage classes provides insight into how the systems influence fluid flow within these systems. These storage reservoirs contain fluids that may include natural gas, oil, or saline water—any of which may impact CO2 storage. The data gathered during these small-scale projects provide valuable information regarding specific formations that have not been evaluated for the purpose of CO2 storage. Specific objectives of small-scale field projects in the RCSP Validation Phase include:

  • Confirm storage resources and injectivity established 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 permitting 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 estimates.

The Validation Phase has accounted for 19 total small-scale field projects. These projects have helped to facilitate future CCS opportunities in North American and provided a foundation for implementation of the large-scale field tests in the Development Phase. By Summer 2014, over 1 million metric tons of CO2 have been injected by the 19 RCSP Validation Phase Field projects.

The geologic data acquired through these studies have been instrumental in further refining of regional CO2 storage resource calculations within each RCSP. The completed tests have provided valuable information to better understand each region's geologic CO2 storage potential and determine specific areas within each RCSP that are in need of future research.

Other activities include refining regional characterizations, public outreach and education, and regulatory compliance issues for the respective field projects. The knowledge gained from these validation procedures and tests can be used to develop commercially viable technologies that will be integral to a carbon management strategy. The results of the field tests will prove that the regional capacity and injectivity exists for commercialization. Lessons learned from these validation phase projects are being integrated into the larger-scale projects in the Development Phase, which includes more detailed characterization, injection, and monitoring of larger volumes of CO2 in subsurface formations. DOE is compiling the lessons learned from the RCSPs in a series of best practices manuals.
