MGSC will conduct a “huff-and-puff” field test of Enhanced Oil Recovery (EOR) and geologic carbon dioxide sequestration by injecting CO2 into a producing oil well, letting it sit for 3-5 days, restarting well production and measuring changes in flow.
- MGSC is one of 7 regional partnerships created by DOE in 2002
- The rural, flat agricultural site, an existing oil field for over 65 years, was chosen from 38 sites in June 2005.

- Geologic sequestration of CO2 is one of the most promising ideas to curtail greenhouse gas (GHG) emissions. Deep underground porous rock capped by impermeable rock can trap the GHGs.
- EOR can also boost oil production if injection increases well pressure or reduces oil viscosity and increases flow.
- A previous 45 ton CO2 injection increased production fourfold but petered out. This test will also measure the geologic sequestration retention.
Wikipedia: “CCS applied to a modern conventional power plant could reduce CO2 emissions to the atmosphere by approximately 80-90% compared to a plant without CCS. Capturing and compressing CO2 requires much energy and would increase the fuel needs of a plant with CCS by about 10-40%. These and other system costs are estimated to increase the cost of energy from a power plant with CCS by 30-60% depending on the specific circumstances.”
Wikipedia: “A major concern with CCS is whether leakage of stored CO2 will compromise CCS as a climate change mitigation option. For well-selected, designed and managed geological storage sites, IPCC estimates that CO2 could be trapped for millions of years, and are likely to retain over 99% of the injected CO2 over 1000 years.”
