Abstract: Characterization of Fractured Reservoir and Simulation of Fluid Flow Therein: Application of Wavelet Transformations

SAHIMI, MUHAMMAD, U. of Southern California

We describe a unified and novel approach to characterization of fractured reservoirs and simulation of fluid flow therein. The method is based on a novel application of wavelet transformations (WT). We describe how WTs can de-noise the data, uncover their special features and spatial distribution, identify the spatial distribution of the reservoir's fractures and faults, and analyze seismic data. After constructing the geological model of the reservoir based on this analysis, WTs perform a realistic and highly efficient scale up of the model. In the fluid flow simulations, wavelet basis functions provide very accurate numerical solution of the flow equations. The results of the simulations are then analyzed by WTs in order to understand their implications.Hence, WTs provide a unified and efficient approach to every stage of characterization of a complex reservoir, simulation of fluid flow therein, and analysis of the simulation results. The method is demonstrated by its application to characterization of a fractured carbonate reservoir and simulation of three-phase flow in the reservoir.
