Project Description

Under this project the Colorado School of Mines is developing a quantitative approach for understanding and predicting geomechanical effects from large-scale carbon dioxide (CO2) injection, including rock deformation and fracturing. Through laboratory analysis and numerical modeling, the project is assessing and validating CO2 flow, storage potential, and the risk of leakage in porous and fractured reservoirs.

Project Benefits

The project is developing an understanding of injection pressure to induce geomechanical effects, including rock deformation and fracturing processes, on CO2 storage systems. This will help end users to evaluate improving reservoir utilization by understanding how faults and fractures affect the flow of CO2; and ensuring CO2 storage permanence. Specifically, the study is performing laboratory fracture and mechanical deformation studies and using that data to model CO2-injection induced rock mechanical processes to quantify flow, storage, and potential leakage pathways as well as remediation measures.
