Fluid flow in porous systems driven by capillary pressure is one of the most ubiquitous
phenomena in nature and industry, including petroleum and hydraulic engineering as well …

Spontaneous imbibition in shale is commonly observed during and after hydraulic fracturing.
This mechanism greatly influences hydrocarbon recovery in shale plays, therefore attracting …

A model for gas transport in shale is proposed by accounting for three major fluid flow
mechanisms in shale stratum, which is modeled as a 3D fractal media. The proposed …

Spontaneous imbibition has been proved to be a promising enhanced oil recovery method
for tight reservoirs, but the mechanisms of spontaneous imbibition oil recovery (SIOR) are …

Imbibition is very common, occurring in life, material, chemistry, and energy. It plays an
important role in enhanced oil recovery (EOR). The development of many reservoirs is …

The study characterizes power-law fluid through charged fibrous porous media with spatial
fractional-derivative and fractal geometry. Seepage flow of power-law fluid across fractal …

In this work, theoretical modelling, quasi-three-dimensional (quasi-3D) simulations and
micromodel experiments are conducted to study spontaneous imbibition with gravity in …

In the exploitation of tight oil and gas reservoirs, multi-stage hydraulic fracturing technology
is mainly used and a complex system of fractures and matrix is formed after fracturing. In the …

Pre-Darcy flow is widely found in many naturally porous media, such as low-permeability
clay. Nonflowing liquid boundary layers strongly influence fluid flow in low-permeability …

The energized hydraulic fracturing technology of “energizing, hydraulic fracturing, shut-in,
and flowback” has achieved good development results in some shale oil fields. The …
