Veltmeijer, A.V. (author), Naderloo, M. (author), Pluymakers, Anne (author), Barnhoorn, A. (author)Induced earthquakes are still highly unpredictable, and often caused by variations in pore fluid pressure. Monitoring and understanding the mechanisms of fluid-induced fault slip is essential for seismic risk mitigation and seismicity forecasting. Fluid-induced slip experiments were performed on critically stressed faulted sandstone samples,...journal article 2024

Shirmohammadi, F. (author), Draganov, D.S. (author), Veltmeijer, A.V. (author), Naderloo, M. (author), Barnhoorn, A. (author)Seismic interferometry (SI) retrieves new seismic responses, for example reflections, between either receivers or sources. When SI is applied to a reflection survey with active sources and receivers at the surface, non-physical (ghost) reflections are retrieved as well. Ghost reflections, retrieved from the correlation of two primary...journal article 2024

(author)Seismic interferometry (SI) retrieves new seismic responses between receivers or sources using, e.g., cross-correlation. Applying SI to a reflection survey with active sources and receivers at the surface, one retrieves ghost reflections besides the physical reflections. Ghost reflections are retrieved from the correlation of two primary...conference paper 2023

Martuganova, E.M. (author), Buisman, M. (author), Barnhoorn, A. (author)We conducted laboratory experiments using large-scale samples (height: 0.47, diameter: 0.39 m) of basalt and marble coiled with telecommunication fibre. The fibre optical cable was converted to an array of densely spaced receivers (0.01 m) using distributed acoustic sensing (DAS) technology, and the source was placed on top of the samples. We...conference paper 2023

Veltmeijer, A.V. (author), Naderloo, M. (author), Barnhoorn, A. (author)Robust and reliable prediction of (induced) earthquakes remains a challenging task. Seismicity predictions are made using probabilistic models, precursors such as average earthquake size distribution. Pore pressure variations cause stress perturbations along pre-existing fault planes in the subsurface, resulting in shear slip and seismicity....conference paper 2023

Naderloo, M. (author), Ramesh Kumar, K. (author), Hernandez, Edgar (author), Hajibeygi, H. (author), Barnhoorn, A. (author)Considering the storage capacity and already existing infrastructures, underground porous reservoirs are highly suitable to store green energy, for example, in the form of green gases such as hydrogen and compressed air. Depending on the energy demand and supply, the energy-rich fluids are injected and produced, which induces cyclic change of...journal article 2023

Kortram, J. (author), Barnhoorn, A. (author), Pluymakers, Anne (author)Geothermal energy production often involves use of corrosion inhibitors. We performed rock mechanical experiments (room temperature; confining pressure of 10/20/30 MPa) on typical reservoir rocks (Bentheim sandstone and Treuchtlinger limestone) in contact with two different inhibitor solutions or with demineralized water. The sandstone...journal article 2023

Pluymakers, Anne (author), Bakker, R.R. (author), Ter Steege, F.B. (author), Versluis, B. (author), Barnhoorn, A. (author)Many rocks contain planar heterogeneities, in the form of open fractures, veins and/or stylolites, but scarce data exist on how strength and fracture pattern formation is affected by the presence of a singular planar heterogeneity in an otherwise uniform matrix. The mechanics of stylolite-bearing and/or fractured limestone is of interest to...journal article 2023

Janssen, M.T.G. (author), Draganov, D.S. (author), Barnhoorn, A. (author), Wolf, K.H.A.A. (author)As part of a seismic monitoring project in a geothermal field, where the feasibility of re-injection and storage of produced CO<sub>2</sub> is being investigated, a P- and S-wave seismic velocity characterisation study was carried out. The effect of axial and radial (up to 42 MPa) stress, pore pressure (up to 17 MPa), pore fluid (100% brine...journal article 2023

Naderloo, M. (author), Veltmeijer, A.V. (author), Jansen, J.D. (author), Barnhoorn, A. (author)Recent laboratory and field studies suggest that temporal variations in injection patterns (e.g., cyclic injection) might trigger less seismicity than constant monotonic injection. This study presents results from uniaxial compressive experiments performed on Red Felser sandstone samples providing new information on the effect of stress...journal article 2023

Veltmeijer, A.V. (author), Naderloo, M. (author), Barnhoorn, A. (author)With human activities in the subsurface increasing, so does the risk of induced seismicity. For mitigation of the seismic hazard and limiting the risk, monitoring and forecasting are essential. A laboratory study was performed to find precursors to fault failure. In this study, Red Pfaelzer sandstones samples were used, which are analog to the...abstract 2022

(author)In July 2021, passive seismic data has been recorded on a network of geophones at the CarbFix2 injection site at Hellisheiði, Iceland. This data is processed using seismic interferometry to get an image of the injection reservoir. The data is split up into noise panels. Panels dominated by body-wave energy are selected using an illumination...conference paper 2022

de Hoop, S. (author), Voskov, D.V. (author), Bertotti, G. (author), Barnhoorn, A. (author)Fracture networks are abundant in subsurface applications (e.g., geothermal energy production, CO<sub>2</sub> sequestration). Fractured reservoirs often have a very complex structure, making modeling flow and transport in such networks slow and unstable. Consequently, this limits our ability to perform uncertainty quantification and increases...journal article 2022
