CT scan data of jetted boreholes
datasetposted on 11.03.2019 by Richard Bakker, A. (Auke) Barnhoorn
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
CT scan data (raw files: .IMA), derived from a medical grade CT scanner as installed at the TU Delft GSE laboratory (Siemens Somatom Volume Zoom). Imaged samples depict borehole geometries produced by water jet drilling under mechanical stress using a true triaxial apparatus. Details on experimental conditions for each test can be found in Bakker et al., "A laboratory study on radial jet drilling in true triaxial stress conditions" (in prep). Image slices (format: .IMA) can be opened with for example imageJ (load stack) or Avizo (import image stack). All slices have individual metadata on acquisition parameters. pixelsize: 0.293 mm/pixel, slice-distance: 0.6 mm.
