Numerical simulation of CO2 injection into deep saline aquifers
In the last two centuries, atmospheric concentrations of carbon dioxide (CO2) have augmented by about 35% as a result of increased anthropogenic emissions. To reduce these emissions, geologic Carbon Capture and Sequestration (CCS) has been advanced as an emerging technology. Current estimations report that 60% are of the total storage capacity under the subsurface is included in deep saline for...
متن کاملCO2 modeling in a deep saline aquifer: a predictive uncertainty analysis using design of experiment.
When field data are limited, stratigraphic models are used instead of detailed, fully heterogeneous models (FHM) to represent deep saline aquifers in numerical simulations of CO2 storage. This study evaluates parameter sensitivity and prediction uncertainty of three stratigraphic models of decreasing complexity (i.e., facies, layered, formation) against that of a FHM. For select simulation outc...
متن کاملCoupled Hydromechanical Modeling of Co2 Sequestration in Deep Saline Aquifers
Sequestration of carbon dioxide (CO2) in deep saline aquifers has emerged as an option for reducing greenhouse gas emissions to the atmosphere. The large amounts of supercritical CO2 that need to be injected into deep saline aquifers may cause large fluid pressure increases. The resulting overpressure may promote reactivation of sealed fractures or the creation of new ones in the caprock seal. ...
متن کاملInfluence of Geological Parameters on Co2 Storage Prediction in Deep Saline Aquifer at Industrial Scale
Here we examine the consequences of uncertainty with respect to geological parameters, using large-scale 2D models. We also investigate ways to reduce prediction uncertainty, either by showing how a parameter’s influence is negligible for a given project design, or by showing for which parameters additional data will significantly increase the quality of prediction. TOUGH2/ECO2N is used to simu...
متن کاملA Pore-scale Hydro-mechanical Coupled Model for Geomaterials
We present a model for fluid-saturated granular media coupled flow and mechanical deformation. The fluid is assumed to be incompressible and the solid part is assumed to be a cohesive granular material. Forces exerted by the fluid in motion are determinated and applied to solid particles. We derive a finite volumes formulation of the flow problem and we couple it to a discrete element method (D...
