In the last decades, micro- and nanoflow in porous media are becoming a hot research area, as they are relevant in many petroleum engineering processes, such as hydrocarbon extraction in petroleum reservoirs, deployment of unconventional resources within coal bed methane, and shale and tight formation, as well as heat transfer/exchange enhancement using nanoparticle and environmental focus processes, such as groundwater contamination and CO₂ sequestration.

A thorough understanding of the micro- and nanoflow in porous media will lead to a better comprehension of fluid flow and/or heat transfer behavior in the unconventional tight porous media and will contribute to an improved engineering application. This special issue emphasizes fundamental scientific innovation on theoretical and mathematical modeling of fluids, including micro/nanofluids, flow, and transport properties in porous media, with an emphasis on contributions which increase the basic understanding of theoretical and experimental approaches of flow and transport through porous media and their application to engineering and scientific problems.

We invite authors to contribute original research and critical review articles related to all aspects of micro- and nanoflow in porous media by means of theoretical and experimental approaches.

Potential topics include but are not limited to the following:

• Nonlinear flow
• Interface effect of pore surface
• Fractal-based approaches to characterize tight porous media
• 3D digital models and pore network modeling
• Nanoscale heat and/or mass transfer
• Nanoparticle flow through porous media
• Application in both conventional and unconventional oil and gas reservoirs
