The imbibition of water with surfactants, including spontaneous imbibition and forced
imbibition, is of great significance for enhanced oil recovery (EOR) in tight sandstone …

The main oil reservoirs in the Bohai area, with thick layer, high average permeability, high
heterogeneity, loose rock cementation, and high oil viscosity, have entered the stage of …

There are more than 40% remaining oil trapped in the reservoir in the mature oilfield even
after second and tertiary recovery processes. High performance chemical agent was …

The adsorption behavior of asphaltenes on the mineral surfaces seriously reduces oil
recovery, which is dependent on the molecular structure, surface properties of the inorganic …

In the complex fluid environment of subterranean rocks, some mineral components are
easily hydrated, which hinders the accumulation and utilization of hydrocarbon. However …

Polymeric surfactant can simultaneously thicken aquous phase and reduce water–oil
interfacial tension (IFT), which makes it present a great application prospect in the oilfield …

With the maturity of waterflooded reservoirs, owing to serious heterogeneity, the fluid will
channel through the thief zone, leading to considerable remaining oil unrecovered in the …

The flow of two immiscible liquids in porous media can lead to fluid mixing, resulting in
emulsions—where one phase is dispersed as droplets in the other. In reservoir rocks …

Oil in water (O/W) emulsion flooding is a successful enhanced oil recovery (EOR) approach
for sandstone reservoirs, while few studies have been conducted to examine the EOR …

Polymer microsphere transport in porous media widely appears in oil field development.
However, the migration and plugging mechanisms of the microspheres at the pore-throat …
