Abstract

We present a new approach to quantify the representative quality of pore-scale samples of porous media. It is shown that the flow field uniformity serves as a reliable criterion to decide if the computed flow properties are representative at larger sample sizes. The proposed approach is computationally inexpensive and requires minimal effort to implement. We rely on the correlation matrix of flow field to quantify the representative quality of the computed flow properties at the pore scale. Using this approach, we have been able to study several pore-networks and a high-resolution image of a sandstone, and quickly answer if the computed flow properties from these pore-networks/images are representative of the actual media.
