Abstract
A big challenge in digital rock physics today is the speed with which X-ray tomography data can be processed, i.e. the time it takes from collecting the raw X-ray projections over the image reconstruction and analysis to derivation of the rock petrophysical properties. This process is often labour intensive and the results get biased due to manual decisions made on image processing parameters. It becomes an even large challenge when we want to produce significant relevant results, i.e. we have to sample a lot of material. Here we present of automated procedure to perform this task and provide an example of the determination of porosity and surface area from a series of chips extracted from core plugs of Upper Maastrictian Chalk.
