Abstract: non-intrusive model reducti on computational method using hypersurfaces representation has been developed for reservoir s imulation and further applied to 3D fluvial channel problems in this work. Th is is achieved by a combination of a radial basis function (RBF) interpolation an d proper orthogonal decomposition (POD) method. The advantage of the met hod is that it is generic and non-intrusive, that is, it does not require m odifications to the original complex source code, for example, a 3D unstructured me sh control volume finite element (CVFEM) reservoir model used here. The ca pability of this non-intrusive reduced order model (NIROM) based on hypersu rfaces representation has been numerically illustrated in a horizontal ly layered porous media case, and then further applied to a 3D complex fluvial channel case. By comparing the results of the NIROM against the solutions obtain ed from the high fidelity full model, it is s hown that this NIROM results i n a large reduction in the CPU computation cost while much of the details are captured.
