Carbon mineralisation in basalts is a promising cost-effective way to permanently store CO2 in view of climate change mitigation. In this work, the impact of carbon mineralisation on the hydromechanical properties of a basaltic sample is studied. Unlike pr ...

Permanent CO storage in basalts through mineralisation offers a promising solution for reducing carbon emissions and mitigating climate change. This study focuses on the impact of potential mineralisation on the flow properties of the basaltic material. Fl ...

Caprock formations, such as shales, play a key role in safe underground CO2 storage since they serve as a hydromechanical barrier that prevents migration of the injected CO2 to the surface. While their hydromechanical response is important to ensure their ...

Here, we describe the testing of geophysical techniques to monitor and evaluate a pilot site for in-situ CO2 mineral storage in Helguvik, Iceland. In addition to hydraulic spinner tests and borehole logging data, the stratigraphic sequence of the reservoir ...

Fissures can have a significant impact on caprock integrity in the context of carbon capture and storage (CCS). In this campaign, the sealing capacity of a pre-fissured caprock material, the Opalinus Clay shale, is studied with real time x-ray imaging duri ...

The development and construction of offshore wind farms requires the correct estimation of the friction that can be mobilised at the rock/grout interface. In conventional studies, the shear behaviour of a joint is usually investigated with laboratory tests ...

The presented experimental study focuses on the hydro-mechanical characterisation of a shale caprock (Opalinus Clay) in contact with carbon dioxide. The objective of this paper, consists in the evaluation of the material's sealing capacity in terms of entr ...

The potential of underground CO2 storage relies on the sealing efficiency of an overlaying caprock that acts as a geological barrier. Shales are considered as potential caprock formations thanks to their favourable hydro-mechanical properties. In this work ...

The hydromechanical response of a Wyoming-type bentonite (MX-80) and its interface with steel was studied in terms of shear resistance under different hydration levels. A series of shear tests under constant normal stress were performed in total suction co ...

Opalinus Clay is a fine-grained sedimentary geomaterial with a mineral composition consisting mainly of silicates, carbonates and quartz. Due to its favourable barrier properties, this geomaterial has been selected as the host rock for the underground disp ...
