The project is designed to leverage tools and technologies to improve methods for defining geomechanical risk factors (like geomechanical stress) at carbon dioxide (CO2) storage sites. Project research is utilizing regional geologic data collected from previous and ongoing projects. The methodologies developed under the project may have the potential to enable CO2 storage in many fractured reservoirs through risk reduction, therefore increasing overall CO2 storage capacity by enabling more storage options. In addition, the project has the potential to cut costs by reducing the need for additional expensive testing and logging. The research will benefit both enhanced oil recovery (EOR) and CO2 storage applications.
This project is focused on analyzing geomechanical risk factors related to CO2 storage. It will generate a systematic inventory of site-specific geomechanical parameters for potential CO2 storage reservoirs, develop a methodology for characterizing deep rock formations, evaluate the effects of natural fracture systems on CO2 injectivity, and perform a comprehensive geomechanical evaluation of potential reservoirs. The project will improve the understanding of potential storage capacity and permanence by better understanding the geomechanical effects related to CO2 injection and storage. Specifically, this project is characterizing fractured reservoirs stress/strain setting in the Appalachain Basin region, assessing the CO2storage processes based on rock core tests and geophysical logging, and evaluating the potential storage and effects of subsurface geomechanical deformation.
