Abstract

For demands of high-precision and fast calculation in reservoir simulation, proper orthogonal decomposition method is applied to reduce the degrees of freedom for governing equations of reservoir simulation. A reduced-order model for single-phase reservoir flow is established. Model results are compared in 90 cases with uniform/non-uniform, isotropic/anisotropic permeability. Relative deviations of POD results from finite difference (FDM) results are in the magnitude of 10^-6∼ 10^-3. Computational time of the POD reduced-order model is about 1/3000∼1/9000 of that of FDM.
