Abstract

This work presents a comparative study of the Oda tensor and upscaling methods for evaluating permeability in fractured fields. This comparison enables the results obtained using the Oda method to be calibrated with those obtained using the upscaling method, avoiding the drawbacks of the Oda method mentioned in the literature. As the upscaling method is not an alternative for making estimates across the entire reservoir, the approach taken is to run both methods for only a small number of blocks, and then to evaluate the relationship between the results given by the two methods for several increments of fractures. An example with data conditional to synthetic statistics of orientation, density, and aperture is presented. Fractures are simulated in 3D within a grid block and the same set of fractures is evaluated with the two methods. The results confirm the bias reported in the literature and show that the upscaling method can be used for calibrating permeability values given by the tensor method.
