WESTCARB Salt River

Project Overview

The third phase of this project is to safely inject CO2 into the most promising saline formation for CO2 storage found during the second phase, track the movement of and monitor the injected CO2 to ensure compliance with environmental, health and safety related requirements. After completing the test, a comprehensive assessment of storage potential, relative to sources of CO2, will be conducted. The scope of work for Phase III consists of injecting approximately 2000 tonnes of CO2 into the most promising storage formation and using a suite of monitoring tools to track migration and ensure compliance with all requirements. CO2 will be purchased and transported to the site for injection. Results from the test will be used to extrapolate the regional storage potential of the Colorado Plateau in Northern Arizona. The capacity of the storage formations will be assessed relative to the size of regional sources of CO2.
