New Applications for Beneficial Reuse of Coal Combustion Ash Authors Ms. Anne Oberlink - United States - University of Kentucky Center for Applied Energy Research Dr. Bob Jewell - United States - University of Kentucky Center for Applied Energy Research Dr. Thomas Robl - United States - University of Kentucky Center for Applied Energy Research Mr. Curtis Wilie - United States - Commonwealth Energy Technologies Mr. Jim Crenshaw - United States - Commonwealth Energy Technologies Mr. Scott Hoskins - United States - Commonwealth Energy Technologies Ms. Hailey Mattingly - United States - Office of Energy Policy, Commonwealth of Kentucky Abstract The University of Kentucky Center for Applied Energy Research, along with its industrial partner, Commonwealth Energy Technologies, Inc., with the support of the Office of Energy Policy, has initiated a project to explore and develop new uses for both current production and ponded coal combustion fly ash. This research will characterize and modify the fly ash for enhanced oil & gas recovery and provide materials for improved efficiency and safety of plugging and abandonment of wells in Kentucky. This effort is partly based on new fly ash technology for recovering and enhancing production from pre-existing oil and/or gaswells. In some cases, the rejuvenated wells have surpassed their original production levels. This technology has been successfully pilot-tested in heritage oil and gas fields in Eastern Texas and the Texas panhandle and is currently well into implementation. Ash fracking is a patented technology that uses a micro-proppantproduced from coal combustion fly ash to open and maintain micro-fractures in shale and sandstone. This approach reduces the energy needed for the operation by as much as 95%, improving efficiency and reducing greenhouse gas emissions. This green technology is conducted with simple pumping equipment, creating a small operational footprint, a crucial factor in Eastern Kentucky’s topography. Because using fly ash eliminates the need for viscosity modifiers, it results in a simpler post-fracking cleanup. It also uses less water and can reuse well water, eliminating environmental contamination. This approach also provides theultimate disposal solution for fly ash, storing it thousands of feet below the earth’s surface.
