GRAND CHALLENGE: SIMULATION OF MULTISCALE GEOLOGIC SYSTEMS FOR ULTRA-LONG TIMESoptimization efforts. Specifically, the next-generation computational tools can be used to designdisposal strategies that explicitly correlate storage requirements and reservoir capacity whileengineering the pressure perturbation that is unique to CO 2 sequestration such that maintenanceof cap-rock/wellbore seal integrity is ensured. This is particularly important in the context ofmanaging storage sites within a given basin, where explicit account must be taken of interferencebetween multiple injection projects. In terms of verifying predicted containment performance, onboth individual and multiple site scales, the advanced simulators can be used to identifyappropriate suites of geophysical and geochemical monitoring techniques, and imaging andsampling strategies. With respect to remediation strategies that may be needed, the newcomputational capabilities can be used to design appropriate corrective actions (e.g., brinewithdrawal to reduce or laterally smooth the injection-triggered pressure perturbation). Finally,next-generation simulators can play a critical role in risk assessment by quantifying theuncertainties that bound performance prediction though comprehensive sensitivity analyses thatestablish the impact of key uncertain model parameters.Pursuit of these research directions is expected to have the following impacts:• Improved science-based decision making for site selection, licensing, operation, and longtermmonitoring.• More efficient and economic management of subsurface systems for storage ofanthropogenic byproducts, energy production, and aquifer management.• The proposed development of general stochastic mathematical and numerical frameworks forlarge-scale dynamic nonlinear systems will allow rigorous quantification of the uncertaintyand risk associated with site selection, operation, and long-term monitoring of large-scalesubsurface storage projects.104 Basic Research Needs for Geosciences: Facilitating 21 st Century Energy Systems
