Contact model and numerical modelling results: “Compaction of the Groningen Gas Reservoir Sandstone: Discrete Element Modelling Using Microphysically Based Grain-Scale Interaction Laws”
Mehranpour, Mohammad Hadi
2021
Reservoir compaction, surface subsidence and induced seismicity are often associated with prolonged hydrocarbon production. Recent experiments conducted on the Groningen gas field’s Slochteren sandstone reservoir rock, at in-situ conditions, have shown that compaction involves both poro-elastic...
Data from seismic slip-pulse experiments simulating induced earthquake rupture in the Groningen gas field
Hunfeld, Luuk Bernd
2021
Rock materials show dramatic dynamic weakening in large-displacement (m), high-velocity (~1 m/s) friction experiments, providing a mechanism for the generation of large, natural earthquakes. However, whether such weakening occurs during induced M3-4 earthquakes (dm displacements) is unknown. We...
Data supplement to: Mapping and classifying large deformation from digital imagery: application to analogue models of lithosphere deformation
Broerse, Taco | Krstekanic, Nemanja | Willingshofer, Ernst
2021
The dataset consists of the original top-view and cross-section digital photographs of the model presented in Broerse et al. (2020) (Mappingand classifying large deformation from digital imagery: application to analogue models of lithosphere deformation.). The top-view images have been taken at...
Surface DEM’s data and cross-sections from analogue experiments of subduction initiation performed in the Tectonic Laboratory (TecLab) at Utrecht University
Auzemery, Antoine | Willingshofer, Ernst
2020
In order to show the spatial and temporal evolution of deformation and associated surface topography, we present our results in terms of surface scans and final cross sections. The latter are pictures recorded at the end of the experiment. They are obtained at two-third of their width....
Top-view and cross-section photographs from analogue experiments of strain partitioning around a rigid indenter performed in the Tectonic modelling laboratory (TecLab) at Utrecht University
Krstekanić, Nemanja | Willingshofer, Ernst
2020
This dataset contains original top-view and cross-section photographs of 12 crustal-scale analogue models. Top-view photographs were taken in regular time intervals from the beginning until the end of each experiment (for details see below). Cross-section photographs were taken at the end of...
Rock magnetic properties, IODP Site U1518, depth interval 250-400 mbsf
Greve, Annika
2021
Rock magnetic properties for hemipelagic sediments sampled at Site U1518 of IODP Expedition 375 (depth interval: 250-400 mbsf). Data and file information: ‘hysteresis_parameters_curated.txt’ summarizes composition specific parameters from hysteresis and backfield curves....
Hydrothermal friction data of samples obtained from outcrops of the Mai'iu Fault, Papua New Guinae
Niemeijer, Andre Rik
2020
General friction and rate and state friction data of powdered fault gouge samples derived from outcrops of the Mai'iu Fault, Papua New Guinae, which is one of the world's most rapidly slipping low-angle normal faults, The experiments show that gouges from the shallowest portion of the fault...
Frictional slip weakening and shear-enhanced crystallinity in simulated coal fault gouges at subseismic slip rates
Liu, Jinfeng | Hunfeld, Luuk Bernd
2020
We report seven velocity stepping (VS) and one slide-hold-slide (SHS) friction experiments performed on simulated fault gouges prepared from bituminous coal, collected from the upper Silesian Basin of Poland. These experiments were performed at 25-45 MPa effective normal stress and 100 ℃,...
Mechanical data from rotary shear experiments on material derived from outcrops felsic and mafic rocks in the East African Rift Zone
Hellebrekers, Nina
2019
In all experiments, multiple series of velocity-steps were performed to obtain the velocity dependence of friction. The data can be modeled using rate-and-state friction equations (see Marone, 1998). We used the rate-and-state friction tool included in the XLOOK program to invert the data for...
Friction and compaction data of simulated fault gouges derived from the Basal Zechstein caprock of the Groningen gas field
Hunfeld, Luuk Bernd
2019
We investigated the rate-and-state frictional properties of simulated anhydrite-carbonate fault gouge derived from the Basal Zechstein caprock overlying the seismogenic Groningen gas reservoir in the NE Netherlands. Direct shear experiments were performed at in-situ conditions of 50-150 °C...
