Hydrogen (H 2) is currently considered a clean fuel to decrease anthropogenic greenhouse
gas emissions and will play a vital role in climate change mitigation. Nevertheless, one of …

Abstract Underground hydrogen (H 2) storage (UHS) and carbon dioxide (CO 2) geo-
storage (CGS) are prominent methods of meeting global energy needs and enabling a low …

The wettability is a critical property that governs the in situ fluid distribution, fractional flow,
and hydrocarbon trapping in the porous media. This topic is of immense interest to the …

In gas geo-storage operations, the injected ex-situ gas will displace the in-situ formation
brine and partially occupy the porous space of the target rock. In case of water-wet rock, the …

Nanopore structure development in shale is intimated with lithofacies that demonstrates a
large variety in different formations. It is critical to differentiate and quantify the separate …

Spontaneous imbibition (SI), which is a process of displacing a nonwetting fluid by a wetting
fluid in porous media, is of critical importance to hydrocarbon recovery from fractured …

Liquid spreading on open surfaces is a widely observed phenomenon. The physics of liquid
spreading has become more complex when the surface is porous like paper or fabrics due …

The spontaneous imbibition process involves the fluid flow driven by gravity and capillary
forces between the matrix and fractures, which is a critical mechanism in oil production in …

Many naturally occurring porous media contain different types of grains with different
wettabilities, therefore, understanding the effect of wettability heterogeneity on multiphase …

Spontaneous imbibition (SI) has been used widely to characterize shale wettability and pore
structures, which can significantly affect the migration and accumulation processes of shale …
