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 …

Hydrogen is considered a viable energy vector, it can be produced through the electrolysis
of water and stored as a gaseous phase in the subsurface. Hydrogen storage in saline …

Deep saline aquifers are among the most favorable geological sites for short-and long-term
carbon geosequestration. Injection of CO2 into aquifers causes various hydro-physical …

Sandstone formations are widely considered for underground sequestration of CO 2. During
CO 2 injection, fines migration can cause pore blockage, which reduces sandstone …

To mitigate climate change and adopt renewable energy, energy storage is crucial and can
be done in the form of hydrogen gas (H 2). Subsurface geologic reservoirs are positioned to …

The invasion of low-salinity fluids into saline-lacustrine reservoirs may induce salt
dissolution, resulting in significant changes in petrophysical properties. Accurate …

To date, many laboratory-based core scale (ie flooding) studies have focused on relatively
homogeneous rock samples (eg Berea sandstone) to study the migration characteristics of …

Deep saline aquifers and depleted carbonate reservoirs are generally considered promising
locations for subsurface CO 2 storage. However, carbonate minerals particularly calcite can …

Chemical and/or physical interactions between the storage rock and injected and in-situ
created solutes are expected to occur during many underground CO 2 storage projects. The …

Mineral occlusions in cleats are known to considerably reduce coal permeability. Sequential
steady state core flooding experiments with aqueous hydrochloric acid (HCl) solutions were …
