Geothermal Project on TU Delft Campus - DEL-GT-01 and DEL-GT-02 Wireline Logs

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>.<br>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 [e-mail] 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. <br><strong>Contents </strong><br>This data set includes the following open-hole logs:Gamma Ray,Spectral Gamma Ray,Caliper, Bulk Density,Neutron Porosity,Micro-Resistivity Image,Dipole Sonic (including full-waveform),Ultra-Sonic Borehole image, andNuclear Magnetic Resonance.<br>The ZIP file DELGT01_DELGT02_wireline_logs.zip contains the following data files:<br>Composite log image files in PDF format, at scales of 1:200 or 1:1000Log data files in LAS Format version 2.0Log data files in DLIS format (including metadata files in .meta and .dlis.scan.txt formats)<br>A complete description of the data collection methods is provided in the <strong>Drilling Report of the campus geothermal doublet </strong>(DOI to be assigned). Details of the log files are in the README.txt file.<br>Note that the exact same set of logs will be made publicly available (in 2028, approximately) by NLOG (<em>Nederlandse Olie- en Gasportal</em>):DEL-GT-01: https://www.nlog.nl/nlog-mapviewer/brh/3888610845?lang=nlDEL-GT-02: https://www.nlog.nl/nlog-mapviewer/brh/3895797327?lang=nl
