Abstract: A dense volumetric grid coming from an oil/gas reservoir simulation output (V) is translated into a compact representation that supports desired features such as interactive visualization, geometric continuity, color mapping and quad representation. A set of four control curves (P (U, 0), P (1, W), P (U, 1), P (0, W)) per layer results from processing the grid data, and a complete set of these 3-dimensional surfaces represents the complete volume data and can map reservoir properties of interest to analysts. The processing (C) results yield a representation of reservoir simulation results which has reduced data storage requirements and permits quick performance interaction between reservoir analysts and the simulation data. The degree of reservoir grid compression (B) can be selected according to the quality required, by adjusting for different thresholds, such as approximation error and level of detail.
