InterPore Distinguished Lecture by Prof. Lyesse Laloui
We are pleased to host Lyesse Laloui to present his Kimberly-Clark Distinguished Lecture.
Carbon Dioxide Injection into Deep Aquifers: A Geomechanical Perspective
Carbon Capture and Underground Storage (CCUS) is a critical strategy for achieving negative emissions targets as atmospheric CO2 concentrations reach 50% above pre-industrial levels. Yet injection-induced geomechanical risks threaten containment. This lecture evaluates CO2 sequestration in deep aquifers through a geomechanical lens. Initially, basaltic storage is examined for its mineralization potential, where hydromechanical testing reveals permeability reductions due to micro-pore clogging. Transitioning to supercritical CO2 in sedimentary formations, coupled thermo-hydro-mechanical (THM) processes are shown to govern caprock integrity and fault stability. Validated against the In Salah benchmark, THM modeling quantifies surface uplift and thermal stresses arising from cold injection. Finally, a North Oman carbonate case study demonstrates how 3D finite-element simulations integrate capacity, injectivity, and containment criteria for site selection. Ultimately, rigorous geomechanical assessment ensures storage security, bridging theoretical coupling with engineering scalability for global CCUS deployment.
