The Plains CO2 Reduction (PCOR) Partnership has put into place a Web-based decision support system (DSS) to assist its research team in developing and assessing a wide range of sequestration opportunities for the PCOR Partnership region. The DSS is a central repository for the characterization information that is being collected through the project tasks. It allows the PCOR Partnership to browse, query, analyze, and download data regarding CO2 sequestration in the PCOR Partnership region. Outputs from the DSS will be used in the PCOR Partnership model during the identification of CO2 sequestration opportunities.
