The data set contains conventional- as well as distributed fiber-optic logging data recorded during the drilling of Well RN-34, located in the Reykjanes geothermal filed, Iceland. Published as well is part of the source code used to produce the data based figures in the SPE Journal paper Raab et al., 2019.

To structurally and petrophysically characterize the rock mass in the Ivrea-Vebarno Zone, a comprehensive downhole geophysical dataset from has been collected in borehole 5071_1_B (IGSN ICDP5071EH30001) of the ICDP-DIVE project located in the Central part of the Ivrea-Verbano Zone at the Linea Cadorna in Migiandone near Ornavasso. Natural gamma ray (GR), magnetic susceptibility (MS), mud parameter (MP), dual laterolog resistivity (DLL), full waveform sonic (FWS), acoustic televiewer (ATV), optical televiewer (OTV), single point resistance (SPR) logs and vertical seismic profiling data (VSP) are recorded.
The borehole data is complemented by magnetic susceptibility measurements conducted on the cored rocks on site during the drilling campaign and by density measurements of 96 core sections using a multi sensor core logger (MSCL) after the drilling campaign at the BGR Core Repository in Berlin-Spandau. Additionally, for 15 whole-round core samples, the bulk density as well as ultrasonic velocities are measured at ambient conditions in the laboratory at Montanuniversität Leoben.
Several logging campaigns have been conducted. The logging data contain logs from a logging campaign conducted by GFZ-Operational Support Group (OSG) after the drilling operation in December 2022 and from complementary logging operations carried out by Montanuniversität Leoben and the University of Lausanne in June 2023. The repository data include: processed and/or interpreted properties of the well log data; zero-offset VSP P- and S-wave velocities; and petrophysical properties inferred from the core measurements. The full description of the data and methods is provided in the data description file.
