MGSC Huffn Puff

Project Overview

CO2 was injected (normally as a gas) into a producing well (the “Huff” phase), the well was shut, and CO2 was allowed to penetrate the formation, and then the well was placed back on production (the “Puff” phase). The test was conducted at the Loudon Field in Fayette County, Illinois. A total of 43 tons (39 metric tons) of CO2 was injected over a five-day period into the Mississippian Weiler Sandstone formation at a depth of approximately 1,550 feet.
