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...

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."

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...

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

Ronald Pijnenburg | Berend Antonie Verberne | Suzanne Hangx | Christopher James Spiers

2019

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...

Stress-cycling data uniaxial compaction of quartz sand in various chemical environments

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...

Rotary Shear Experiments on Glass Bead Aggregates

Evangelos Korkolis

2021

Constant sliding velocity (i.e. rate of rotation) friction experiments on mm-thick layers of glass beads, under room temperature and humidity conditions. Stick-slip in sheared granular aggregates is considered to be an analog for the intermittent deformation of the earth’s lithosphere via...

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...

Microstructural data used in “Drill core from seismically active sandstone gas reservoir yields clues to internal deformation mechanisms”

Berend Antonie Verberne | Suzanne J.T. Hangx | Ronald P.J. Pijnenburg | Maartje F. Hamers | Martyn R. Drury | Christopher J. Spiers

2022

Europe’s largest gas field, the Groningen field (the Netherlands), is widely known for induced subsidence and seismicity caused by gas pressure depletion and associated compaction of the sandstone reservoir. Whether compaction is elastic or partly inelastic, as implied by recent experiments, is...

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...
