The Cranfield, Mississippi, CO2 Injection Test Site

The Cranfield Field, Mississippi is a 10,000 ft-deep reservoir that produced ~62 MMbbl of oil and ~670 MMSCF of gas from the 1940’s to the 1960’s and is being retrofitted for tertiary recovery. CO₂ injection into the reservoir started in July 2008. More recently, University of Texas at Austin team has begun injecting CO₂ in the saline aquifer downdip of the reservoir. The team is monitoring CO₂ migration and fate through an array of dedicated tools to thoroughly understand CO₂ behavior in the subsurface. Funding for this work is provided by the U.S. Department of Energy / NETL.
