WELL REPRESENTATION IN RESERVOIR SIMULATION MODELS CONSIDERING THE IMPACT OF DISCRETE FRACTURE NETWORK UPSCALING

The goals of this work are (1) to evaluate the impact of Discrete Fracture Networks (DFN) upscaling methods on new wells placed in the simulation model and (2) to develop a well representation proposal of new wells in naturally fractured reservoirs simulation models. Three DFN permeability upscaling methods (Oda, Oda Corrected, and Flow-based) are used at three model scale fidelities (high, medium-high, and medium). The results suggest more uncertainty of well-dynamic data in medium fidelity models. Our reference case is defined as the combination of fidelity scale and upscaling method that produces less variation in well-dynamic data. This results in a model constructed with a high-fidelity scale and Flow-based method (linear pressure). The proposed well representation suggests substituting the well index in the matrix and fracture systems of the medium-fidelity model with the reference model’s WI. We show the necessity of this correction with a field-scale application.
