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...

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...

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...

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...

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....

Supporting data set for manuscript "Remediation of annular gas migration along cemented wellbores using reactive mineral fluids: experimental assessment of sodium bicarbonate and sodium silicate-based solutions"

Timotheus K.T. Wolterbeek

2021

Brief description of the Data: This folder contains data for a study on reactive sealing of microannuli along wellbore casing-cement interfaces. The data set consists of four Microsoft Excel Worksheets, containing volume, flow rate, and pressure data with time for reference and reactive flow...
