Fast assessment of geological uncertainties during CO2 storage using RRM

Scaling up of CO2 storage projects to meet the IPCC targets requires fast screening methods that provide a quick assessment of geological uncertainties, storage volumes, and possible CO2 migration pathways. Such screening methods enable the efficient identification of potential candidate fields for CO2 storage that are then subjected to more detailed reservoir characterisation studies. This presentation will introduce recent extensions and applications of the open source Rapid Reservoir Modelling (RRM) framework for CO2 storage applications. An updated flow diagnostics framework will be discussed that quantifies how contacted reservoir volumes evolve over time. A case study that investigates how geological uncertainties at the Northern Lights CCS project impact CO2 migration pathways and storage volumes will also be presented. These new examples will highlight how RRM can be used to integrate geoscience and reservoir engineering from the start to design more meaningful reservoir models for CO2 storage applications in less time.
