The Mountaineer Project - Midwest Regional Carbon Sequestration ...

Preliminary Site Characterization• In the Midwest region, Mt. Simon Sandstone is the most prominent CO 2injection candidate formation with estimated storage capacity exceeding100 billion tonnes of CO 2 .• Mt. Simon was one of the initial candidates for Mountaineer site.However, in the deep basins such as the Appalachian Basin, it becomesthin and has low porosity.• In addition, formations, such as Rose Run Sandstone and CopperDolomite have potential for large-scale storage in the Appalachian Basin.• The region has significant shale and other cap rock and there is no majorfaulting in the rock structure.• The Mountaineer site is located above the three formations of interest.• Seismic testing was used to further characterize the area around theproposed well. This yielded information about the layers of rocksurrounding the well.7Regional Geology• Thick sequences of sedimentary rock formbroad basins and arches in Midwest• Site located in Appalachian Basin•No other deep wellswithin 20 miles•AEP#1 = ”wildcat well”84
