We present CobWeb 1.0, a graphical user interface for analysing tomographic images of geomaterials. CobWeb offers different machine learning techniques for accurate multiphase image segmentation and visualizing material specific parameters such as pore size distribution, relative porosity and volume fraction. We demonstrate a novel approach of dual filtration and dual segmentation to eliminate edge enhancement artefact in synchrotron-tomographic datasets and provide the computational code.

The geothermal potential of a carbonate reservoir in the Rhine-Ruhr area, Germany, was investigated by field and laboratory investigations. The carbonate layer of interest is approx. 150 m thick; located at 4 to 6 km depth; and might extend below Essen, Bochum, and Dortmund. We proposed focusing on discontinuities striking NNW–SSE for geothermal applications, as these are the most common, strike in the direction of the main horizontal stress, and dominate reservoir fluid flow.

In this work, we combined different imaging and experimental measuring methods for analysis of cross-scale effects which reduce permeability of tight reservoir rocks. Simulated permeability of digital images of rocks is often overestimated, which is caused by non-resolvable clay content within the pores of a rock. By combining FIB-SEM with micro-XCT imaging, we were able to simulate the true clay mineral abundance to match experimentally measured permeability with simulated permeability.

We perform a three-dimensional numerical study of the fluid–solid deformation at the pore scale. We show that seismic wave velocities exhibit strong azimuth-, angle- and frequency-dependent behavior due to squirt flow between interconnected cracks. We conclude that the overall anisotropy mainly increases due to squirt flow, but in some specific planes it can locally decrease as well as increase, depending on the material properties.

Short summary
We quantify the effects that 3-D fractures with realistic distributions of aperture have on seismic wave attenuation and velocity dispersion. Attenuation and dispersion are caused by fluid pressure diffusion between the fractures and the porous background. We show that (i) both an increase in the density of contact areas and a decrease in their correlation length reduce attenuation and (ii) a simple planar fracture can be used to emulate the seismic response of realistic fracture models.

Short summary
The technique of X-ray computed tomography (CT) is widely used in multiple disciplines such as medicine, industry and earth sciences. However, quantitative analysis from the reconstructed images are subject to errors due to technical limitations and subsequent evaluation workflows. The paper addresses the uncertainties related to the estimation of porosity from these images and compares the results with laboratory measurements. Accurate porosity estimates are linked to sufficient resolution.

Time reverse imaging is a method for locating quasi-simultaneous or low-amplitude earthquakes. Numerous three-dimensional synthetic simulations were performed to discover the influence of station distributions, complex velocity models and high noise rates on the reliability of localisations. The guidelines obtained enable the estimation of the localisation success rates of an existing station set-up and provide the basis for designing new arrays.

Short summary
Hot fluids and hydraulically conductive rock formations are essential for the accessibility of geothermal resources. We use numerical modeling techniques to investigate how seismic waves change their shape in presence of these factors. We demonstrate how to parameterize such models depending on the local geology and as a function of depth. Finally, we show how the attenuation, i.e. the energy loss of the wave, can be indicative for permeable rock fractures saturated with a fluid of specific type.

X-ray microtomography image processing involves artefact reduction and image segmentation. The beam-hardening artefact is removed, applying a new algorithm, which minimizes the offsets of the attenuation data points. For the segmentation, we propose using a non-linear classifier algorithm. Statistical analysis was performed to quantify the improvement in multi-phase classification of rock cores using and without using our advanced beam-hardening correction algorithm.

Understanding the fluid circulation in fault zones is essential to characterize the thermochemical evolution of hydrothermal systems in mountain ranges. The study focused on a paleo-system of the Pyrenees. Phyllosilicates permit us to constrain the evolution of temperature and redox of fluids at the scale of the fault system. A scenario is proposed and involves the circulation of a single highly reducing hydrothermal fluid (~300 °C) that evolves due to redox reactions.

This study improves geochemical mapping by addressing the uncertainty in defining element associations. It clusters the study area by element similarity, recognizes elemental associations for each cluster, and then detects anomalies indicating underlying geological processes. This method is applied to a region in China, confirming its effectiveness and consistency with the geology. This study can enhance geochemical mapping for mineral exploration and improve geological-process understanding.

The Taodonggou Group mudstone was deposited in a warm, humid, and hot paleoclimate with strong weathering. The parent rocks of the Taodonggou Group mudstone are felsic volcanic rocks and andesites, with weak sedimentary sorting and recycling and with well-preserved source information. The Taodonggou Group mudstone was deposited in dyoxic fresh water–brackish water in intermediate-depth or deep lakes with stable inputs of terrigenous debris but at slower deposition rates.

Orogenic gold deposits in Paleoproterozoic belts in northern Finland have been explored not only for gold but because of the occurrences of economically important concentrations of base metals, especially cobalt. In this study we are testing the vectoring capacities of pyrite trace element geochemistry, combined with lithogeochemical and sulfur isotopic data in the Raja gold–cobalt prospect (northern Finland), by using multivariate statistical data analysis.

The Hurricane fault is a major and active normal fault located in the southwestern USA. This study utilizes the geochemistry and dating of calcite veins associated with the fault to characterize ancient groundwater flow. Results show that waters moving along the fault over the last 540 000 years were a mixture of infiltrating fresh water and deep, warm salty groundwater. The formation of calcite veins may be related to ancient earthquakes, and the fault influences regional groundwater flow.

To understand the fate of carbon in subducted oceanic sediments and crust, we studied carbonate phases in rocks from the Mariana subduction zone. These show that carbon is liberated from the downgoing plate at depths less than 20 km. Some of the carbon is subsequently trapped in minerals and likely subducts to greater depths, whereas fluids carry the other part back into the ocean. Our findings imply that shallow subduction zone processes may play an important role in the deep carbon cycle.

Short summary
Sediments containing hydrates dispersed in the pore space show a characteristic seismic anomaly: a high attenuation along with increasing seismic velocities. Recent major findings from synchrotron experiments revealed the systematic presence of thin water films between quartz and gas hydrate. Our numerical studies support earlier speculation that squirt flow causes high attenuation at seismic frequencies but are based on a conceptual model different to those previously considered.
