Three-dimensional imaging of drill core samples using synchrotron computed microtomography
Fundamental theories of rock structure are limited by the absence of high resolution, pore level, three dimensional images which could be used for statistical analysis. The ability to produce such images in a non-destructive manner would also allow for repeated measurements of dynamic processes such as fluid motion which could be correlated to the medium properties. One aspect of this funded work is the production of cross sectional images of rock drill core samples with one micron resolution. This work is being done by Keith Jones and Per Spanne of Brookhaven National Laboratory using beam lines X-17 and X-26 of the National Synchrotron Light Source. Jones's annual report will provide a description of the year one progress in this area. The second aspect of this work is the topological and statistical analysis of the pore structure of the three dimensional images provided by our BNL collaborators. We report here on the progress in this area that has been made in year one. Year one effort has focused on the problem of definition of pore space in any given slice (image filtering), analysis of the filtered images via 2-point correlation structure, and on the development of software to trace the connectivity of pores throughout the cross sectional images. The report is divided into the following sections: 2 - a description of the 3D data sets that have been provided by our BNL collaborators; 3 data filtering; 4 - 2-point correlation function analysis; 5 - development of connectivity tracing software; and 6 - proposed work for year two.
