| Summary |
"Carbon dioxide sequestration has been proposed as a way to reduce anthropogenic carbon dioxide emissions. Several characteristics are required in order for a geologic formation to be suitable for sequestration. There must be an impermeable confining layer to restrain CO₂ migration toward the surface, the porosity and permeability must be high enough to allow for long term injection and substantial storage capacity, and the formation must be strong enough for long term injection to occur without inducing fractures. In this work, The Reagan and Lamotte Sandstones near Springfield, Missouri were evaluated for the potential for carbon dioxide sequestration. The Derby-Doe Run, Davis, and Bonneterre Formations provided a confining layer for these two sandstones. City Utilities Exploratory Well #1 was drilled through these formations and over 600 feet of core was collected. In addition, open hole well logs were run, hydrogeologic tests were performed, and geomechanical tests were performed. Lab measurements were made for porosity, permeability, Young's Modulus, and Poisson's Ratio on collected core. Well logs, hydrogeologic data, and geotechnical data were analyzed to find estimates for porosity, permeability, Young's Modulus, Poisson's Ratio, fracture breakdown pressure and minimum in situ stress. The confining layer had low permeability and higher Young's Modulus and Poisson's Ratio values than the target sandstones. However, the analysis of the Reagan and Lamotte Sandstones revealed that these zones have low storage capacity and may not be suitable for carbon dioxide sequestration"--Abstract, leaf iii. |
