In-Situ Stress Magnitude Data from the Greater Ruhr Region (Germany) Derived from Hydrofracturing Tests and Borehole Logs

Abstract

This compilation presents in-situ stress magnitudes derived from hydrofracturing tests and borehole logs carried out in six, now abandoned, coal mines and two coal bed methane boreholes at depths between 600 and 1950 m within the greater Ruhr region in western Germany. All stress information was analysed and compiled in a standardized format and quality-ranked, using the established quality ranking schemes of the World Stress Map (WSM) project, for reliability and comparability. The compilation displays A-C quality of in-situ stress orientation data records. The database presented here is the world's largest public database of stress magnitudes from a single region and presents unique and high-quality stress input data for future reservoir and geomechanical numerical models and should aid the subsurface operations in the region. This dataset supplements the Stress Magnitude Database of Germany (https://doi.org/10.5880/wsm.2020.004) with additional 429 data records, doubling the amount of available stress data records for Germany from 568 to 997. More detailed information on the WSM quality ranking scheme, guidelines for the various stress indicators, and software for stress map generation and the stress pattern analysis is available at http://www.world-stress-map.org.
