Short summary
In this study, we investigate the evolution of fault reactivation potential in the greater Ruhr region (Germany) in respect to a future utilization of deep geothermal resources. We use analytical and numerical approaches to understand the initial stress conditions on faults as well as their evolution in space and time during geothermal fluid production. Using results from our analyses, we can localize areas more favorable for geothermal energy use based on fault reactivation potential.

Understanding the stress and strain conditions in the Earth's crust is crucial for various activities, such as oil and gas exploration and assessing seismic hazards. In this article, we have updated the database of moment tensor focal mechanisms for Greater Iberia. We conducted kinematic and dynamic analyses on the selected populations, determining the average focal mechanism, strain and stress orientations, and tectonic regime. The orientation for horizontal compression is primarily N154° E.

Obtaining reliable estimates of the subsurface state distributions is essential to determine the location of, e.g., potential nuclear waste disposal sites. However, providing these is challenging since it requires solving the problem numerous times, yielding high computational cost. To overcome this, we use a physics-based machine learning method to construct surrogate models. We demonstrate how it produces physics-preserving predictions, which differentiates it from purely data-driven approaches.

The rotation of the principal stress axes in a fault structure because of a rock stiffness contrast has been investigated for the impact of the ratio of principal stresses, the angle between principal stress axes and fault strike, and the ratio of the rock stiffness contrast. A generic 2D geomechanical model is employed for the systematic investigation of the parameter space.

It is generally assumed that faults have an influence on the stress state of the Earth’s crust. It is questionable whether this influence is still present far away from a fault. Simple numerical models were used to investigate the extent of the influence of faults on the stress state. Several models with different fault representations were investigated. The stress fluctuations further away from the fault (> 1 km) are very small.

We present experimental data collected in 2015 at Äspö Hard Rock Laboratory. We created six cracks in a rock mass by injecting water into a borehole. The cracks were monitored using special sensors to study how the water affected the rock. The goal of the experiment was to figure out how to create a system for generating heat from the rock that is better than what has been done before. The data collected from this experiment are important for future research into generating energy from rocks.

When stresses yield a critical value, rock breaks and generate pathways for fluid migration. Thus, the contemporary undisturbed stress state is a key parameter for assessing the stability of deep geological repositories. In this workshop you can ask everything you always wanted to know about stress (but were afraid to ask), and this is divided into three parts. 1) How do we formally describe the stress field? 2) How do we to actually measure stress? 3) How do we go from points to 3D description?

Short summary
The subsurface is subject to constant stress. With increasing depth, more rock overlies an area, thereby increasing the stress. There is also constant stress from the sides. Knowledge of this stress is fundamental to build lasting and safe underground structures. Very few data on the stress state are available; thus, computer models are used to predict this parameter. We present a method to improve the quality of the computer models, even if no direct data on the stress state are available.

Numerical methods can be used to estimate the stress state in the Earth’s upper crust. Measured stress data are needed for model calibration. High-quality stress data are available for the calibration of models for possible radioactive waste repositories in Switzerland. A best-fit model predicts the stress state for each point within the model volume. In this study, variable rock properties are used to predict the potential stress variations due to inhomogeneous rock properties.

Short summary
Stress data predicted by a geomechanical–numerical model are mapped onto 3D fault geometries. Then the slip tendency of these faults is calculated as a measure of their reactivation potential. Characteristics of the faults and the state of stress are identified that lead to a high fault reactivation potential. An overall high reactivation potential is observed in the Upper Rhine Graben area, whereas the reactivation potential is quite low in the Molasse Basin.

Short summary
In numerical geomechanical models, an initial stress state is established before displacement boundary conditions are applied in order to match calibration data. We present generic models to show that the choice of initial stress and boundary conditions affects the final state of stress in areas of the model domain where no stress data for calibration are available. These deviations are largest in the vicinity of lithological interfaces, and they can be reduced if more stress data exist.

The recent crustal stress state is a crucial parameter in the search for a high-level nuclear waste repository. We present results of a 3D geomechanical numerical model that improves the state of knowledge by providing a continuum-mechanics-based prediction of the recent crustal stress field in Germany. The model results can be used, for example, for the calculation of fracture potential, for slip tendency analyses or as boundary conditions for smaller local models.

Short summary
Reactivation of tectonic faults can lead to earthquakes and jeopardize underground operations. The reactivation potential is linked to fault properties and the tectonic stress field. We create 3D geometries for major faults in Germany and use stress data from a 3D geomechanical–numerical model to calculate their reactivation potential and compare it to seismic events. The reactivation potential in general is highest for NNE–SSW- and NW–SE-striking faults and strongly depends on the fault dip.

Short summary
The Earth's crust is subject to constant stress which is manifested by earthquakes at plate boundaries. This stress is not only at plate boundaries but everywhere in the crust. A profound knowledge of the magnitude and orientation of the stress is important to select and build a safe deep geological repository for nuclear waste. We demonstrate how to build computer models of the stress state and show how to deal with the associated uncertainties.

Short summary
Short summary
Knowledge about the stress state in the upper crust is of great importance for many economic and scientific questions. However, our knowledge in Germany is limited since available datasets only provide pointwise, incomplete and heterogeneous information. We present the first 3D geomechanical model that provides a continuous description of the contemporary crustal stress state for Germany. The model is calibrated by the orientation of the maximum horizontal stress and stress magnitudes.

Short summary
The authors assemble an in situ stress magnitude and orientation database based on 429 hydrofracturing tests that were carried out in six coal mines and two coal bed methane boreholes between 1986 and 1995 within the greater Ruhr region (Germany). Our study summarises the results of the extensive in situ stress test campaign and assigns quality to each data record using the established quality ranking schemes of the World Stress Map project.
