AN INTEGRATED APPROACH TO COMPUTE PHYSICAL PROPERTIES OF CORE SAMPLES

We introduce an integrated approach to compute physical properties of core samples on very large micro-CT images and nano-CT images. On the same segmented 3d image, a whole range of diverse effective material properties are computed. In addition, we study the behavior of these material properties under compression. Where data is available, our methods are compared to other state of the art solvers on a large complex Berea sandstone dataset [1]. Our newest flow solver is 3-6 times faster than the fastest solver in [2], scales well for up to 32 processors and promises to solve 3k by 3k by 3k domains in as little as 180GB of memory. An additional benefit of this work is that the reported range of permeabilities from the benchmark [2] can be narrowed down significantly.
