Modeling Of Leakage Through Fault-Zone Structures In Co2 Geological Storage, Dayna Rodriguez Zambrano
LSU Master's Theses
Faults intersecting target geological CO2 storage zones have important implications for storage integrity. Potential leakage pathways due to fluid over-pressurization are investigated in this project to ensure long-term containment of injected CO2. Numerical flow simulations coupled with a geomechanical module are presented in this work with the purpose of determining the extent of CO2 up-fault migration, the driving mechanisms of leakage and the corresponding response of quantified pore pressure and stress variations.
This study uses dual-continuum models performed by using CMG (2017) to correctly account of flow through fractures in a fault damage zone. Numerical simulations …
