Hydraulic fracturing of unconventional oil/gas shales has changed the energy landscape of
the US Recovery of hydrocarbons from tight, hydraulically fractured shales is a highly …

Geological media exhibit heterogeneities in their hydraulic and chemical properties, which
can lead to enhanced spreading and mixing of the transported species and induce an …

Carbon sequestration, infrastructure rehabilitation, brownfields clean-up, hazardous waste
disposal, water resources protection and global warming—these twenty-first century …

We consider transport of a solute that undergoes a nonlinear heterogeneous reaction: after
reaching a threshold concentration value, it precipitates on the solid matrix to form a …

Reactive transport (RT) couples bio-geo-chemical reactions and transport. RT is important to
understand numerous scientific questions and solve some engineering problems. RT is …

Abstract Systems dominated by heterogeneity over a multiplicity of scales, like porous
media, still challenge our modeling efforts. The presence of disparate length-and time …

We investigate the temporal scaling properties of mixing in heterogeneous permeability
fields with variances ranging from very small (σlnK2= 0.01) to very large (σlnK2= 9). We …

Mixing-driven reactions in porous media are ubiquitous and span natural and engineered
environments, yet predicting where and how quickly reactions occur is immensely …

Shales will play an important role in the successful transition of energy from fossil-based
resources to renewables in the coming decades. Aside from being a significant source of …

This work comprehensively reviews the equations governing multicomponent flow and
reactive transport in porous media on the pore-scale, mesoscale and continuum scale. For …
