This dataset contains pressure, temperature, and flow records of periodic pumping tests. The tests were conducted in 4 boreholes located near Kemnader See on the outskirts of Bochum, Germany. The pumping tests were conducted in two configurations: 1) single-borehole testing, and 2) hydraulic dipole testing. In single-borehole testing, the pumping was carried out in a single borehole (pumping borehole) and the remaining three boreholes were used for monitoring of pressure interference signals. In hydraulic dipole testing, pumping was carried out in two boreholes simultaneously with half a cycle phase difference (water was produced from one borehole and injected into another), and the two remaining boreholes were used for monitoring. In both configurations, pressure and temperature were recorded in all four boreholes, whereas flow rate was recorded only in the operational borehole(s). The dataset also includes spectral parameters of the pressure and flow records, determined using fast Fourier transformation (FFT).
The lithosphere-asthenosphere boundary (LAB) marks the base of the Earth’s outer layer where heat is transferred primarily by conduction as compared to prevailing convective heat transport below. Spatial variations in LAB depth reveal the differential evolution of tectonic systems (e.g., rifts and orogens), thus enabling a better understanding of geodynamic processes. Further, the topography of the LAB exerts control on the coupling of the lithosphere to asthenospheric flow, modulating the distribution of present-day stresses and active deformation of the tectonic plates. We have derived global depth variations of the LAB from temperature-converted shear-wave tomography models assuming that the threshold temperature between conduction and mantle convection is 1300 °C. Shear-wave velocity in the mantle is controlled by both in situ pressure-temperature conditions and mineralogical rock composition. Therefore, our velocity-to-temperature conversion builds on a framework of rock physical properties generated through a Gibbs free energy minimization to determine thermodynamically stable phase and mineral assemblages throughout upper mantle pressure and temperature conditions. In this data publication, we provide thermal LAB depths corresponding to one European-scale and three global-scale tomography models. The data release includes (i) a data description file with information on the input tomographic models, the conversion method and spatial variations in LAB depth (illustrated); and (ii) four data files with LAB depth values spatially sampled according to the input tomography models.
This dataset contains a high-fidelity three-dimensional (3D) reservoir model developed for numerical simulation using the CMG STARS reservoir simulator. The model is based on the geological framework of the Groß Schönebeck geothermal research platform and discretized into a Cartesian grid, which provides the numerical basis for thermo-hydraulic reservoir simulations. Key physical parameters, including rock petrophysical and fluid properties, have been incorporated into the model based on the interpretation of subsurface data acquired at the Groß Schönebeck site. The dataset comprises simulator input files developed to model a closed-loop geothermal system using the existing wells E GrSk 3/90 and Gt GrSk 4/05. Two completion depths, 3,600 m and 3,800 m measured depth (MD), were evaluated to investigate the performance of a coaxial deep borehole heat exchanger (DBHE) system. The numerical simulations assess the effects of completion depth, circulation flow rate, and injection temperature on the thermal performance of the closed-loop system.
This data set contains hypocentral parameters (latitude, longitude, depth, local magnitude, and origin time) for 13566 aftershocks of the 2019, M6.4 Durrës, Albania earthquake. Aftershocks were recorded with a 30 station local network, which started operation about two weeks after the and registered for about nine months. Event detections were produced with machine-learning-based tools. Aftershocks were located with a newly derived 1D velocity model with station corrections. Final relocation was done with the double-difference algorithm including cross correlation derived differential travel times. Local magnitudes range from Ml −1.8 to 4.6 with a magnitude of completeness of Mc ≈ 1.
This dataset contains a reservoir model developed for high-fidelity numerical simulation using the CMG STARS reservoir simulator. This three-dimensional (3D) subsurface model is based on a geological framework which has been divided into a Cartesian grid. This grid provides the numerical basis for reservoir simulation. Key physical parameters have been incorporated into the model, including rock petrophysical properties, fluid properties and fracture geometries. These parameters have been derived from the interpretation of subsurface data acquired at the Groß Schönebeck geothermal research platform. To improve predictive reliability, the model was calibrated against field-scale hydraulic test data collected between 2011 and 2013. The numerical model is designed to simulate fracture-dominated enhanced geothermal system (EGS) scenarios within the Rotliegend reservoir. Its primary purpose is to evaluate the performance of different well layouts and multi-stage hydraulic fracture designs in terms of reservoir productivity.
