A total of ~86 m of core were recovered from the producer well DELGT-01, of which 70 m are in a continuous sequence. The purpose was to core the caprock and the upper reservoir deposits. Cores have a diameter of 4 inches and were cut into 1 meter long sections. Each section have been preserved and stabilized within their barrels by injecting foam, and sealing the cores with a wax and a vacuum pack, comprising aluminum and plastic layers to reduce water and oxygen leaving or entering the cores. Prior to any physical or destructive testing on the cores, all preserved 1-meter long cores were scanned in the Geoscience and Engineering Laboratory using the medical CT scanner (Siemens Somatom Volume Zoom CT scanner).

The full End-of-well science programme report can be found here.

A full description of the data set is in the README.docx file.

Acquisition parameters are described in the file DELGT01-cores-macroCT-public.xlsx.

A guide to load these data with open-source software is described in How To Macro CT Scroll Through.pdf.
