Depositional processes and stratigraphic architecture of an exhumed retrogradational to progradational submarine slope succession (Eocene, Aínsa Basin, Spain) Open
Sedimentary successions recording the initiation and evolution of submarine slopes have rarely been documented in outcrop studies. Consequently, the temporal and spatial distribution of subaqueous slope deposits at sub-seismic resolutions …

Feldspar alteration by disequilibrium CO <sub>2</sub> -H <sub>2</sub> O fluids in reservoir sandstones: Implications for CCS Open
Understanding how the minerals in reservoir rocks respond to CO2 injection is vital for the success and safety of Carbon Capture and Storage (CCS) projects. Feldspars are the most common mineral in the Earth’s crust and act as primary fram…

Experimental and microstructural analysis of feldspar solubility in CCS reservoirs Open
Feldspars are a common framework grain in sandstone reservoirs targeted for carbon capture and storage (CCS). They are mechanically weak under reservoir conditions and are very likely to react with CO2 injected into saline aquifers or depl…
Dynamic imaging of the effect of pore microstructure factors on fine particle migration and deposition during fluid flow through porous media Open
The migration and deposition of fine particles in porous materials is critical in industries such as energy, pharmaceuticals, and environmental engineering. Using 3D time-lapse synchrotron X-ray imaging, we observe fine particles invading …
Hydrogen-induced mineral alteration: A review in the context of underground hydrogen storage (UHS) in saline aquifers Open
As the world moves away from fossil fuels in a ‘green energy transition’, low-carbon alternatives such as renewable energy technology is becoming progressively abundant. Renewable energy production is extremely weather-dependent, fluctuati…
Carbon isotope stratigraphy and biostratigraphy, and associated organic carbon deposition during the Late Cenomanian to Early Turonian in the Tarfaya Basin, Morocco Open
The Cenomanian-Turonian (C/T) boundary event, also known as Oceanic Anoxic Event 2 (OAE2), is characterised by significant organic carbon preservation and a positive carbon isotope excursion that is recorded globally in sedimentary strata.…

Initiation and evolution of an epicontinental shelf‐slope margin in an actively contracting deep‐water basin: The Eocene Aínsa Basin, southern Pyrenees (Spain) Open
The shelf‐slope margin is a geomorphic zone with a change in gradient between subaqueous shelves and slopes, which extends towards the submarine basin‐floor. It is important because it partitions distinct sedimentary and biogenic processes…
CO2-induced micro-mechanical alterations of mudstone Caprock: Examples from the Mercia Mudstone Group, East Irish Sea Basin Open
Mechanical properties of caprock are important for subsurface energy sequestration as they determine the rock stability under the influence of external forces. Despite some advantages, there is a lack of knowledge regarding the interplay b…

Multi-scale Investigation of a Triassic Sherwood Sandstone Aquifer and Its Impact on Aquifer Thermal Energy Storage Open
The transition of energy supply from mainly fossil sources to low-carbon energy sources is essential for future environmental sustainability. The current worldwide energy demand for heating and cooling in buildings accounts for 40% of the …

Novel application of artificial neural networks to derive lithofacies in the Bunter Sandstone Formation of the UK Southern North Sea Open
The Bunter Sandstone Formation (BSF) in the UK sector of the Southern North Sea is thought to have a significant potential for CO2 storage, which would help the UK achieve net-zero carbon emissions by 2050. During the assessment phase, a r…

4D synchrotron imaging of CO2 transport in reservoir rocks and caprocks: Informing safe CO2 sequestration     Open
Tracking CO2 transport in subsurface rock during geological carbon sequestration has received significant attention. Although X-ray computed tomography (XCT) imaging techniques, visualization and quantification of CO2 behavior has been und…

4D visualisation and analysis of fluid-rock interactions in a caprock for the implication of carbon sequestration and storage Open
The assessment of caprock sealing capability is a crucial component for the safety evaluation of geological carbon storage. This study imaged and modelled acid-rock interactions in a mudstone utilising time-lapse X-ray 3D imaging technique…

Microfacies and diagenetic alteration in a semi-deep to deep lacustrine shale: The Yanchang Formation in the Ordos Basin, China Open
The mineralogical development and diagenetic sequence of lacustrine shales in the Chang 7 Member of the Yanchang Formation in the Ordos Basin are detailed studied to predict exploration potential of shale oil in that area. A model of their…

Microstructure changes as a response to CO2 storage in sedimentary rocks: Recent developments and future challenges Open
Due to the complexity of sedimentary rocks, especially the fine-grained and highly-heterogeneous nature of some argillaceous caprocks in the subsurface, it is challenging to directly characterise the macroscale changes during CO 2 storage.…

The influence of creeping slope failure on turbidity current behaviour Open
Erosional scars, slumps, slides and debrites (mass‐transport deposits) on submarine slopes form relief that influences turbidity current behaviour. However, the interaction of mass‐transport deposit emplacement kinematics (i.e. rapid empla…
