Computing properties such as (relative) permeability, diffusion coefficients or electrical resistivity of rocks based on images (e.g. X-ray or scanning electron microscopy) of their microstructure has recently been a popular, alas computationally intensive, framework for data-based upscaling of such properties that complement and explain lab results. However, employing them efficiently on a large number of samples, such as those acquired in an exploration well, and in sufficient number of scenarios, in order to assess uncertainty or explore parameter space, depends on the ability to cut down the computational time. We have made a significant progress in employing scientific machine/deep learning algorithms and have cut down permeability estimation from 8+ hours down to seconds. We further present the latest work on estimating electrical properties as well as diffusion coefficients in reactive flow (Marcato et al. submitted) using similar approaches. In combination with data hosted in Digital Rocks Portal and open-source code, this research paves the way to an environment that directly links data (often indeed big data on small scales), high performance computing simulation, deep learning prediction as well as automated collection of the data into a searchable library. Last but not the least, the concepts are applicable beyond rocks to estimating properties of other complex/porous structures such as foams, batteries or fuel cells, and micro-vascular networks.
