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

Mariska T.W. Schimmel

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...

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...

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....

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...

Microscopic and spectroscopic data of pseudotachylytes and wall rocks from the Moncuni ophiolite

Oliver Plümper

2020

We investigated the microstructures and geochemistry of pseudotachylytes found within the ophiolitic peridotites and gabbros from the Moncuni area (Lanzo Ultramafic Massif, Western Alps). The pseudotachylytes preserve dry glass and pristine microlites. The presence of garnet and the static...

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...

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...

Microstructural data and microscopic stress measurements of natural mineral-hydration reactions

Oliver Plümper

2022

We investigated the microstructures of periclase-to-brucite hydration domains within marble from the Adamello contact aureole (Italy). The microstructure preserve high differential stresses within the calcite surrounding the hydration domains of up to 1.5 GPa. Samples were investigated using...

Original microstructural data of altered rocks and reconstructions using generative adversarial networks (GANs)

Hamed Amiri

2022

We image two altered rock samples consisting of a meta-igneous and a serpentinite showing an isolated porous and fracture network, respectively. The rock samples are collected during previous visits to Swartberget, Norway in 2009 and Tønsberg, Norway in 2012. The objective is to employ a...

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...
