Addressing Potential Risks And Challenges Of Co2 Geologic Sequestration, Ethan Guyant

Theses and Dissertations

Carbon Capture and Geologic Storage is a viable technology to reduce the concentration of CO2 emitted to the atmosphere, however there remains challenges and risks associated with implementing this technology. One of the challenges, and the focus of Chapter 2, is maintaining the injectivity of the reservoir throughout the entire injection period of a project. While potential risks include the pressurization of the reservoir and the leakage of CO2 and/or brine out of the storage reservoir which is the focus of Chapter 3. A consequence of injecting dry-supercritical CO2 is that it results in salt precipitation in the near well …
