Abstract

Summary

In digital rock physics (DRP) modeling, a fundamental question is how to use the rock images at a small scale to help understanding a model at a larger scale. We investigate a new method of forming an effective median from small-scale structures for the modelling study of a larger scale. First, structure of heterogeneities at a small scale is combined into a pattern, of which the key features can be quantitatively described. Then in a DRP image, the pattern can be detected. The part of the image is replaced with a proper pattern for a simplified DRP model. Similarity analysis using a 1D Gaussian-shaped template is efficient in describing and detecting the key features of porous media. An example of elastic simulation demonstrates that a simplified model is consistent with a model from image segmentation based on grey scale.
