The MRCSP is pleased to report that, based on the successful injection test conducted in the Bass Island Dolomite formation at the Michigan Basin site near Gaylord, Michigan, the partnership is conducting an additional injection test. This expanded testing will further study the behavior of injected carbon dioxide and the performance of the monitoring and computer modeling tools used to track the injected carbon dioxide.
Carbon dioxide is the most common of the manmade greenhouse gases that are believed to contribute to global warming. Concern about global warming has led to efforts to find ways to reduce carbon dioxide emissions to the atmosphere. Storing carbon dioxide deep underground in carefully selected geologic formations is one of several options being studied. This concept is often referred to as geologic sequestration.
During the initial test in early 2008, 10,241 metric tonnes of carbon dioxide were successfully injected into the Bass Island Dolomite formation of the Michigan Basin at a depth of approximately 3500 feet. The MRCSP research team carried out a number of sophisticated measurements around the injection site to track the behavior of the carbon dioxide injected into the formation. These measurements showed a reasonable match with the behavior predicted by the computer model used by the MRCSP team prior to the field test. The field test data will be used to further calibrate the model.
The second extended test will involve injection of up to an additional 50,000 tonnes of carbon dioxide and will be completed by the late summer of 2009. The test will be conducted in compliance with all state and federal permitting requirements.
