“…It can work with relative permeabilities, diffusion and hydrodynamic dispersion, exible boundary conditions (pressure, ow rate, concentration, and temperature) and injection wells, either horizontal or vertical. It can be coupled with a geochemical simulator called ARXIM to account for chemical reactions that can occur in a carbonate reservoir under uid injection (MAURAND et al, 2014). Its equations are based on conservation laws of continuum mechanics, but the viscous uidsolid interaction is modeled using Darcy's empirical equation.To solve the equations, COORES™ uses nite differences and can calculate ow rates, pressure, and chemical species concentrations in multiphase ow.…”

Carbonates are expected to be reactive during the injection of uids as a secondary recovery method in an oil eld reservoir. Desulphated seawater is usually chosen to reduce scaling potential for barium and strontium sulfates at the producer wells. However, desulfation presents some operational di culties, often limiting the platform injection's capacity. The chemical interactions between seawater and carbonate reservoirs affect produced water composition and must be considered for scaling predictions. Reactive transport models had shown that dolomitization increases anhydrite precipitation, reducing sulphate concentration in the produced water. This paper studied the reaction between calcite and three different uids: seawater, seawater without sulphate and seawater without magnesium. All tests were performed in the presence of CO 2 and using a semi-batch reactor. The focus was to analyze the effects of possible dolomitization on sulfate concentration in reservoir conditions. As the scale potential is strongly related to the sulphate concentration, the previous knowledge of this behaviour plays a key role at the water quality decision. Experimental results con rmed simulation predictions.

“…For adequate modeling of complex flow processes that occur in oil reservoirs, it is necessary to take into account the component composition of the phases [1,2]. Accounting for convection, diffusion, phase transitions and chemical reactions makes it difficult to simulate such problems [3][4][5][6].…”

Newton’s method has been widely used in simulation multiphase, multicomponent flow in porous media. In addition, to solve systems of linear equations in such problems, the generalized minimal residual method (GMRES) is often used. This paper analyzed the one-dimensional problem of multicomponent fluid flow in a porous medium and solved the system of the algebraic equation with the Newton-GMRES method. We calculated the linear equations with the GMRES, the GMRES with restarts after every m steps—GMRES (m) and preconditioned with Incomplete Lower-Upper factorization, where the factors L and U have the same sparsity pattern as the original matrix—the ILU(0)-GMRES algorithms, respectively, and compared the computation time and convergence. In the course of the research, the influence of the preconditioner and restarts of the GMRES (m) algorithm on the computation time was revealed; in particular, they were able to speed up the program.
