Geothermal Project on TU Delft Campus – DEL-GT-01 core CT-scan data

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).<br>A full description of the data set is in the <strong>README.docx</strong> file.Acquisition parameters are described in the file <strong>DELGT01-cores-macroCT-public.xlsx</strong>.A guide to load these data with open-source software is described in <strong>How To Macro CT Scroll Through.pdf</strong>. Representative axial images produced with the guide <strong>CT scans Cores DELGT01.pdf</strong>.

本次从生产井DELGT-01中共计回收约86米岩心，其中70米为连续序列。本次取心的目标为盖层（caprock）与上部储集层沉积物。岩心直径为4英寸，并被切割为1米长的岩心段。每一段岩心均在岩心筒内通过注入泡沫进行保存与固定，并通过蜡封与真空包装进行密封；该真空包装由铝层与塑料层组成，以减少水分与氧气进出岩心。在对岩心开展任何物理或破坏性测试之前，所有保存完好的1米长岩心均在地球科学与工程实验室（Geoscience and Engineering Laboratory）内，使用医用CT扫描仪（西门子Somatom Volume Zoom CT扫描仪）完成扫描。
