Abstract

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. For detailed information regarding the measurement geometry, timing of the measurements, and applied processing steps the reader is referred to corresponding publication. The accompanying data description file is explaining the file structure and contents in detail.
