Multi-scale electron microscopy data package of nanoporosity in serpentinite

Alireza Chogani

2023

To determine the nature of serpentinite nanoporosity, we employed multidimensional electron microscopy in conjunction with granular simulations. We investigated samples from the Mid-Atlantic Ridge and the Røragen ultramafic complex (Norway) using scanning and transmission electron microscopy,...

Experimental Evidence for reaction-induced weakening of (Carbonated) Serpentinite Fault Gouges

Lisa Eberhard

2024

We analysed the frictional behaviour of antigorite and carbonated antigorite fault gouges in rotary-shear experiments at Utrecht University. Experiments were conducted at temperatures ranging from 400 - 630 °C, effective normal stresses of 100 - 150 MPa under fluid saturated conditions. This...

We analysed the frictional behaviour of antigorite and carbonated antigorite fault gouges in rotary-shear experiments at Utrecht University. Experiments were conducted at temperatures ranging from 400 - 630 °C, effective normal stresses of 100 - 150 MPa under fluid saturated conditions. This...

µCT data for "A new method for determining fluid flux at high pressures applied to the dehydration of serpentinites"

Lisa Eberhard

2022

Dehydration of serpentine within a subduction zone setting causes the formation of pore space. The porosity and connectivity of the pores is important for fluid flux through these rocks. The pore space preserved within two recovered high-pressure and high-temperature multi-anvil samples was...

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...

Mechanical and microstructural data used in: “Rate-dependent Inelastic Deformation of Slochteren Sandstone: Implication for Reservoir Compaction in the Groningen Gas Field”

Takahiro Shinohara

2025

Hydrocarbon production from sandstone reservoirs causes elastic and inelastic reservoir compaction, potentially leading to surface subsidence and even seismicity, such as observed in the Groningen Gas Field, Netherlands. Inelastic compaction can partly be instantaneous, though...

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...

Mechanical and microstructural data used in: “The effect of strain rate on inelastic strain development in porous sandstones deformed under reservoir conditions”

Takahiro Shinohara

2024

Subsurface human activities, such as fluid extraction from oil or gas sandstone reservoirs, frequently leads to surface subsidence and even induced seismicity, as observed in the Groningen Gas Field, the Netherlands. Subsidence is caused by elastic and inelastic reservoir compaction at depth...

Molecular simulation data package on the dielectric permittivity of nanoconfined geofluids with various salt concentrations

Alireza Chogani

2024

To determine the effect of salinity on the dielectric permittivity of nanoconfined geofluids, we employed molecular dynamics (MD) simulations of saline water confined in calcite slit nanochannels. This data package includes data points, figures, and MD input files to simulate the behaviour of...
