Velocity-dependent slip weakening by the combined operation of pressure solution and foliation development

Niemeijer, Andre

2018

Phyllosilicate-bearing faults are characterized by an anastomosing foliation with intervening hard clasts and are believed to be long-term weak structures. Here, I present results of sliding experiments on gouges of 80 wt% quartz and 20 wt% muscovite, sheared under hydrothermal conditions at...

Mechanical and microstructural data used in the article Pijnenburg et al., Deformation behaviour of sandstones from the seismogenic Groningen gas field: Role of inelastic versus elastic mechanisms

Pijnenburg, Ronald | Verberne, Berend | Hangx, Suzanne | Spiers, Christopher

2015

Hydrocarbon or groundwater production from sandstone reservoirs can result in surface subsidence and induced seismicity. Subsidence results from combined elastic and inelastic compaction of the reservoir due to a change in the effective stress state upon fluid extraction. The magnitude of...

Experimental and model data of aggregate compaction by pressure solution

van den Ende, Martijn

2017

Intergranular pressure solution creep is an important deformation mechanism in the Earth’s crust. The phenomenon has been frequently studied and several analytical models have been proposed that describe its constitutive behavior. These models require assumptions regarding the geometry of the...

Compaction creep data uniaxial compaction of quartz sand in various chemical environments

Schimmel, Mariska | Hangx, Suzanne | Spiers, Chris

2019

We studied the effect of pore fluid chemistry on compaction creep in quartz sand aggregates, as an analogue for clean, highly porous, quartz-rich reservoir sands and sandstone. Creep is specifically addressed, because it is not yet well understood and can potentially cause reservoir...

Mechanical data and microstructures of simulated calcite fault gouge sheared at 550°C

Verberne, Berend Antonie | Chen, Jianye | Pennock, Gillian

2017

The largest magnitude earthquakes nucleate at depths near the base of the seismogenic zone, near the transition from velocity weakening frictional slip to velocity strengthening ductile flow. However, the mechanisms controlling this transition, and relevant to earthquake nucleation, remain...

Mechanical and microstructural data used in: “Inelastic deformation of the Slochteren sandstone: Stress-strain relations and implications for induced seismicity in the Groningen gas field"

Pijnenburg, Ronald | Verberne, Berend | Hangx, Suzanne | Spiers, Christopher

2019

Pore pressure reduction in sandstone reservoirs generally leads to small elastic plus inelastic strains. These small strains (0.1 – 1.0% in total) may lead to surface subsidence and induced seismicity. In current geomechanical models, the inelastic component is usually neglected, though its...

Creep data of (Dotternhausen) Posidonia shale

Rybacki, Erik | Herrmann, Johannes | Wirth, Richard | Dresen, Georg

2020

Experimentally determined data to examine the creep behavior of an immature carbonate-rich Posidonia shale (Dottenhausen), subjected to constant stress conditions at temperatures between 50 and 200 °C and confining pressures of 50–200 MPa, simulating elevated in-situ depth conditions. The...

Fluid-Induced Fault Slip Experiments in the Laboratory on Critically Stressed Saw-Cut Sandstone Samples with High Permeability

Wang, Lei | Kwiatek, Grzegorz | Rybacki, Erik | Bonnelye, Audrey | Bohnhoff, Marco | Dresen, Georg

2019

To understand the physical mechanisms governing fluid-induced seismicity at field-scale fluid injection projects, we conducted fluid-induced fault slip experiments in the laboratory on critically stressed saw-cut sandstone samples with high permeability using different fluid pressurization...

Frictional and microanalytical data of basalts sheared with pressurized H2O- and CO2- rich fluids

Giacomel, Piercarlo | Spagnuolo, Elena | Nazzari, Manuela | Marzoli, Andrea | Passelegue, François | Youbi, Nasrrddine | Di Toro, Giulio

2018

Here we report the raw data of the friction experiments performed on basalt-built faults pressurized with de-ionized H2O, pure CO2, pure Ar, and H2O+CO2 mixtures, respectively (Dataset_friction_basalts.zip). The experiments were designed to assess the effects of the fluid chemistry on fault...

2020

This dataset includes paleomagnetic and rock magnetic analyses from four sediment cores collected on continental slope of Storfjorden and Kveithola trough‐mouth fans (western Spitsbergen margin, southern Svalbard archipelago). In detail, piston core SV-04 was collected during the Spanish...
