“…The numerical simulation of this process requires very fine resolution of the simulation grid which makes it prohibitive for a full field simulation (Elenius et al, 2015). Small scale models can predict CO2 dissolution rate quite accurately, which can be used in various up-scaling models (Gasda et al, 2011;Lagasca, 2014) to predict the migration distance of the CO2 plume in a large aquifer over medium timescale (tens to one hundred thousand years). The left part of Fig.…”

“…This work is the first attempt to create a universal tool for predictive reservoir simulation of CO2 sequestration in aqueous aquifers that takes into account all of the complex mechanisms that effect the macroscopic dissolution rate. This dissolution rate can then be used in a realistic, large-scale reservoir model using simplified physical models (Gasda et al, 2011;Lagasca, 2014) to predict the dynamic of CO2 trapping for medium time scales (i.e., tens to a hundred thousand years).…”

A multi-scale reservoir simulation framework for large-scale, multiphase flow with mineral precipitation in CO2-brine systems is proposed. The novel aspects of this reservoir modeling and simulation framework are centered around the seminal coupling of rigorous reactive transport with full compositional modeling and consist of (1) thermal, multi-phase flow tightly coupled to complex phase behavior, (2) the use of the Gibbs-Helmholtz Constrained (GHC) equation of state, (3) the presence of multiple homogeneous/heterogeneous chemical reactions, (4) the inclusion of mineral precipitation/dissolution, and (5) the presence of homogeneous/heterogeneous formations. The proposed modeling and simulation framework is implemented using the ADGPRS/GFLASH system. A number of examples relevant to CO2 sequestration including salt precipitation and solubility/mineral trapping are presented and geometric illustrations are used to elucidate key attributes of the proposed modeling framework.

A domain decomposition algorithm is introduced to couple nonisothermal compositional gas liquid Darcy and free gas flow and transport. At each time step, our algorithm solves iteratively the nonlinear system coupling the nonisothermal compositional Darcy flow in the porous medium, the RANS gas flow in the free-flow domain, and the transport of the species and of energy in the free-flow domain. In order to speed up the convergence of the algorithm, the transmission conditions at the interface are replaced by Robin type boundary conditions. The Robin coefficients are obtained from a diagonal approximation of the Dirichlet to Neumann operator related to a simplified model in the neighbouring subdomain. The efficiency of our domain decomposition algorithm is assessed on several test cases focusing on the modeling of the mass and energy exchanges at the interface between the geological formation and the ventilation galleries of geological radioactive waste disposal.
