Experimental Study On Co2-Sensitive Polyacrylamide As Potential In-Situ Sealing Agent For Co2 Leakage Pathways In Geological Storage Sites, Iris Laihmen Quan Lopez

Theses and Dissertations

As the world pushes for ‘greener’ technologies and carbon neutrality, efforts have focused on creating novel ways to mitigate humankind’s carbon footprint. Carbon capture and storage (CCS) has become a prevalent technique that has proven to be an effective long-term method to safely relocate excess carbon dioxide (CO₂) into subsurface formations. However, CCS is a newer technique which requires constant monitoring due to potential leakage pathways present in CO₂ storage sites; therefore, a preventive approach to seal leakage pathways is recommended. This dissertation explores the potential of CO₂-sensitive polyacrylamide (CO₂-SPAM) as a novel …
