25 years of geological CO2 storage modeling and simulation: learnings and way forward
Geological CO2 storage at industrial scale is happening today, with nearly 200 Mtons injected in >25 projects in different geological, technical, and economic settings. Simulation technology is a crucial component of any industrial-scale project. The past 25+ years has seen significant improvement in simulation capabilities and performance that aid in producing more robust and reliable solutions, providing practitioners with functional tools to assess risk and manage storage operations.
In this talk, we will review recent developments in CO2 storage simulation and summarize key learnings from the current state of the art. Examples of salt precipitation, convective mixing, and fault-related leakage will be used to represent the diverse array of physical complexity that impacts injectivity, migration and trapping at project scale. The talk will conclude with a discussion of remaining computational challenges, including multi-scale models and stochastic simulation.
Short bio: Dr. Gasda is a Research Director in Computational Geosciences at NORCE and hold a Professor II appointment in the Department of Physics and Technology at the University of Bergen. She leads a national center of excellence in subsurface research, the Centre for Sustainable Subsurface Resources (CSSR). Dr. Gasda’s research and expertise is in computational methods and modeling of multiphase flow in porous media with particular focus on geological CO2 storage. Her research has contributed to improving our understanding of long-term processes in CO2 storage, migration, and containment, including the potential of leakage from legacy wells and faults.
