Preservation of transport properties trend : computational rock physics approach
Abstract/Contents
- Abstract
- Computational rock physics is a rapidly evolving field and as such requires careful quantitative analysis of the components of this technology: resolution, digital sample size, thresholding of the image, as well as the effects of the scale of the computational simulation. In this thesis we address these issues by utilizing various mathematical and statistical techniques. We use 3D CT-scan images of three different samples to determine the effect of resolution. sample size and thresholding of these images have on transport properties trend, specifically porosity-permeability and porosity-formation factor. We compare these trends with laboratory measured trends and theoretical trends. We find that although the absolute transport properties change as we change these parameters, however the trend formed by these transport properties remains unchanged. These results imply that, we can obtain physically meaningful trend from these non-optimally generated samples e.g., by using non-optimal sample size, non-optimal thresholding or non-optimal resolution. However, our analysis is not exhaustive. For example, our range of sample sizes varies only from core scale to micro-pore structure. Also, the samples used in this study are fairly homogeneous sandstones.
