This pilot-scale project demonstrated the process of carbon dioxide (CO2) sequestration in an onshore underground saline formation in eastern Texas, United States. This location was ideal, as very large scale sequestration may be needed in the area to significantly offset anthropogenic CO2 releases. The project involved injecting relatively small quantities of CO2 into the formation and monitoring its movement for several years thereafter. The goals were to verify conceptual models of CO2 sequestration in such geologic structures; demonstrate that no adverse health, safety, or environmental effects will occur from this kind of sequestration; demonstrate field-test monitoring methods; and develop experience necessary for larger-scale CO2 injection experiments.
Recognized by the Carbon Sequestration Leadership Forum (CSLF) at its Melbourne meeting in September 2004.
