Conventional and unconventional hydrocarbon rocks have complicated pore structures with
heterogeneities distributed over various length scales (from nanometre to centimetre or even …

Within the past decade, X-ray micro computed tomography (µCT) has become an advanced
non-destructive tool to analyse the internal structure of opaque materials. In addition to high …

In this paper, experiments and simulations were performed on outcrop samples from Lagoa
Salgada in Rio de Janeiro, Brazil, as a possible analog to one of the most typical Brazilian …

The production and utilization of hydrogen (H 2) as a clean energy source offer a promising
solution towards achieving net-zero carbon emissions. Utilizing sandstone formations for …

The permeability of a pore structure is typically described by stochastic representations of its
geometrical attributes (eg pore-size distribution, porosity, coordination number). Database …

Unpredicted, rapid plume elongation has been observed at subsurface CO 2 storage
projects worldwide, exemplified by the Sleipner project. We show that conventionally …

Representative elementary volumes (REVs) are an important concept in studying
subsurface multiphase flow at the continuum scale. However, fluctuations in multiphase flow …

Pore-scale properties can be obtained by building a reliable digital twin of porous media
through the digital rock physics (DRP) workflow. The two prerequisites of DRP are reliable …

Hydrogen (H 2) storage in porous reservoirs has been explored as a promising solution to
support large-scale H 2 storage and maintain the energy supply and demand balance in …

The concept of linking pore‐scale data to continuum‐scale characteristics of porous media
relies on the existence of a representative elementary volume (REV). The current techniques …
