Hopkins County, KY – MGSC Sugar Creek Field EOR

The MGSC Sugar Creed Field site was one of three Enhanced Oil Recovery (EOR) field validation tests conducted by the MGSC to assess potential for CO2 storage in oil in the Illinois Basin. The project was supported by the U.S. Department of Energy (DE-FC26-05NT42588) and the Illinois Department of Commerce and Economic Opportunity. CO2 was injected at the Sugar Creek Field test site in Hopkins County, IL into the Jackson Sandstone, an oil-bearing sandstone at a depth of 1,850 feet deep. A cumulative 7,230 tons of CO2 was injection at a rate of 20–30 tons per day, and CO2 was produced at the surface at relatively low rates. Oil production increased in surrounding wells nearly 10 bopd above pre-injection rates. Baseline, injection, and post-injection monitoring were conducted until one year after the CO2 injection termination.
