abstract: "<p>An extensive wireline logging campaign was undertaken during the installation of the geothermal doublet on TU Delft Campus, between June and November of 2023. This large suite of open-hole well logs acquired in the reservoir section of both wells, being DEL-GT-01 the producer and DEL-GT-02 the injector, is rarely undertaken in geothermal projects, which makes this data set of <strong>exceptional scientific value</strong>.</p><p><br></p><p>This data set is embargoed until 2025-12-31. However, if you would like to have access to data before its public release, please send us an email at&nbsp;<a href="mailto:geothermal@tudelft.nl" target="_blank">geothermal@tudelft.nl</a>&nbsp;to discuss the possibilities. <strong>Access to data is in principle possible</strong>, if there are no identified conflicts between our research activities and your proposed data use.&nbsp;</p><p><br></p><p><strong><u>Contents </u></strong></p><p><br></p><p>This data set includes the following open-hole logs:</p><ul><li>Gamma Ray,</li><li>Spectral Gamma Ray,</li><li>Caliper, Bulk Density,</li><li>Neutron Porosity,</li><li>Micro-Resistivity Image,</li><li>Dipole Sonic (including full-waveform),</li><li>Ultra-Sonic Borehole image, and</li><li>Nuclear Magnetic Resonance.</li></ul><p><br></p><p>The ZIP file DELGT01_DELGT02_wireline_logs.zip contains the following data files:</p><p><br></p><ul><li>Composite log image files in PDF format, at scales of 1:200 or 1:1000</li><li>Log data files in LAS Format version 2.0</li><li>Log data files in DLIS format (including metadata files in .meta and .dlis.scan.txt formats)</li></ul><p><br></p><p>A complete description of the data collection methods is provided in the <strong>End-of-well science programme report (</strong><a href="https://doi.org/10.4233/uuid:6ce07471-6986-434e-aa24-ad6e1f6714d9" target="_blank"><strong>link here</strong></a><strong>)</strong>.
