Friction and compaction data of simulated fault gouges derived from the Basal Zechstein caprock of the Groningen gas field
Luuk Bernd Hunfeld
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...
Frictional healing data from direct shear slide-hold-slide experiments performed on simulated fault gouges from the Groningen gas field
Luuk Bernd Hunfeld
2020
We investigated the frictional strength recovery (healing) and subsequent reactivation and slip-weakening behaviour of simulated fault gouges derived from key stratigraphic units in the seismogenic Groningen gas field (N.E. Netherlands). Direct-shear, Slide-Hold-Slide (SHS) experiments were...
Intergranular clay films control inelastic deformation in the Groningen gas reservoir: Evidence from split-cylinder deformation tests

Production of oil and gas from sandstone reservoirs leads to small elastic and inelastic strains in the reservoir, which may induce surface subsidence and seismicity. While the elastic component is easily described, the inelastic component, and any rate-sensitivity thereof remain poorly...
Large-scale biaxial experiments on gypsum-gouge faults and a bare PMMA fault: Mechanical data and selected strain and image data
Loes Buijze
2019
Geodetic observations and large-scale laboratory experiments show that seismic instability is preceded by slow slip within a finite nucleation zone. In laboratory experiments rupture nucleation is studied mostly using bare (rock) interfaces, whereas upper crustal faults are typically filled...
Mechanical data from rotary shear experiments on material derived from outcrops felsic and mafic rocks in the East African Rift Zone
Nina Hellebrekers
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...
Frictional properties of simulated shale-coal fault gouges: Implications for induced seismicity in source rocks below Europe’s largest gas field
Jinfeng Liu | Luuk Bernd Hunfeld | André Rik Niemeijer | Christopher James Spiers
2019
We report 21 frictional sliding experiments performed on simulated fault gouges prepared from shale-coal mixtures. Our aim was to investigate the effects of local coal seam smearing on the frictional properties and induced seismogenic potential of faults cutting the Upper Carboniferous source...
Electron Backscatter Diffraction (EBSD) data from metabasaltic fault rocks, Woodlark Rift, Papua New Guinea
Marcel Mizera
2020
Here we provide compositional and crystallographic orientation data on metabasaltic fault rocks exhumed by the Mai’iu fault in the footwall of the Suckling-Dayman Metamorphic Core Complex, SE Papua New Guinea. The present dataset was collected with a SIGMA-VP field emission gun scanning...
Top-view and cross-section photographs from analogue experiments of strain partitioning during coeval indentation and back-arc extension performed in the Tectonic modelling laboratory (TecLab) at Utrecht University
Nemanja Krstekanić
2021
This dataset contains original unaltered top-view and cross-section photographs of 4 crustal-scale analogue models. Top-view photographs were taken at a regular time interval from the beginning until the end of each experiment (for details see below). Cross-section photographs were taken at the...
Stress-cycling data uniaxial compaction of quartz sand in various chemical environments
Mariska T.W. Schimmel
2020
Decarbonisation of the energy system requires new uses of porous subsurface reservoirs, where hot porous reservoirs can be utilised as sustainable sources of heat and electricity, while depleted ones can be employed to temporary store energy or permanently store waste. However, fluid...
Multi-scale electron crystal-orientation diffraction of seismically active carbonate fault rocks
Markus Ohl
2020
We determine the active deformation mechanisms in two active carbonate fault zones in Greece. Detailed slip-system analyses in combination with high-resolution nanostructural investigations show a throughout contribution of crystal plasticity, evident from subgrain-wall misorientations....
