High-precision digital rock construction and electrical property upscaling in tight sandstone

What is it about?

Formation evaluation is an challenging work in tight sandstone formations. A newer method called digital rock physics (DRP) offers a way forward. This paper shows a practical solution for better upscaling formation analysis form pore-scale digital rock modeling and well-logging saturation evaluation.

Why is it important?

This work propose an innovative method for assigning electrical characteristics to voxel units, enabling the integration of multi-resolution images, as well as a novel approach for establishing a new saturation model that improves the accuracy of logging saturation evaluation and provides a foundational model for the optimization of geological sweet spots.
