Contact model and numerical modelling results: “Compaction of the Groningen Gas Reservoir Sandstone: Discrete Element Modelling Using Microphysically Based Grain-Scale Interaction Laws”
Mohammad Hadi Mehranpour
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...
Hydrothermal friction data of samples obtained from outcrops of the Mai'iu Fault, Papua New Guinae
Andre Rik Niemeijer
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...
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
Nemanja Krstekanić | Ernst Willingshofer
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...
Data supplement to: Mapping and classifying large deformation from digital imagery: application to analogue models of lithosphere deformation
Taco Broerse | Nemanja Krstekanic | Ernst Willingshofer
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...
Data from seismic slip-pulse experiments simulating induced earthquake rupture in the Groningen gas field
Luuk Bernd Hunfeld
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...
Surface DEM’s data and cross-sections from analogue experiments of subduction initiation performed in the Tectonic Laboratory (TecLab) at Utrecht University
Antoine Auzemery | Ernst Willingshofer
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....
Rock magnetic properties, IODP Site U1518, depth interval 250-400 mbsf
Annika Greve
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....
Frictional slip weakening and shear-enhanced crystallinity in simulated coal fault gouges at subseismic slip rates
Jinfeng Liu | Luuk Bernd Hunfeld
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 ℃,...
Large-scale biaxial experiments on frictionally heterogeneous faults: Mechanical data and selected strain and image data
Loes Buijze | Yanshuang Guo
2020
Frictional heterogeneity within fault zones is one of the factors proposed to explain the spectrum of slow, intermediate, and fast slip behaviors exhibited by faults in nature. Numerical modeling shows how even a simplified model setup incorporating sliding on a velocity-weakening (VW) patch...
Micro-XCT images, grain size distributions and mechanical data used in: "Uniaxial compaction of sand using 4D X-ray tomography: The effect of mineralogy on grain-scale compaction mechanisms."
Jeroen. F. Van Stappen | Suzanne J.T. Hangx
2020
The mechanical behaviour of sand aggregates is often studied as a proxy for poorly consolidated sands and highly porous sandstones. Only recently research aimed at understanding sand deformation has started to use techniques that allow for direct observation of the in-situ grain-scale...
