Three-dimensional imaging of drill core samples using synchrotron computed microtomography. Progress report, Year two
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 progress in this area. The second aspect of this work is the geometrical and statistical analysis of the pore structure of the three dimensional images provided. This aspect is being carried out at SUNY-Stony Brook; we report here on the progress that has been accomplished to date. Year one I progress was discussed fully in the previous progress report (DOE/ER/14261-1). Year one effort focused on the problem of voxel-by-voxel pore/grain identification of the tomographic images (image filtering), and on analysis of the filtered images via 2-point correlation structure.
