CMI completes Wyoming CO2 storage project drilling

The task of drilling a 12,810-foot-deep CO2 storage test well has been completed by the Carbon Management Institute and its industry partner Baker Hughes.

Scientists aim to use the test well to gauge the feasibility of using southwestern Wyoming's Rock Springs Uplift as a potential CO2 storage site.

The University of Wyoming’s Carbon Management Institute is managing the $16.9-million Wyoming Carbon Underground Storage Project, while the US Department of Energy's Fossil Energy office is co-sponsoring it.

As per preliminary estimates, the Rock Springs Uplift can store 26 billion tons of CO2 over the coming 50 years. Geological setting and proximity to some of biggest sources of CO2 emissions in the state prompted scientists to choose the site for the project, which started in December 2009 and is expected to complete in December next year.

Project scientists collecting data from the test well to gain information about the permeability, geologic structure and other characteristics of the potential storage unit.

A recent study by researchers from the University of Edinburgh revealed that storing CO2 deep underground will not pose any considerable threat to human health. According to the study, the risk of death from exposure to CO2 leaks from underground rocks is merely one in one hundred million.
