Directional self-transportation of tiny droplets is significant in many fields. However, almost all existing studies focus on the phenomenon in air, and to realize similar performance in complex environments, such as oil, is still extremely rare.…
Graphene oxide (GO) is considered as a new type of self‐assembly membrane material. However, it suffering from a low steady state filtration flux as well as unstable performance, resulting in restriction of its practical applications. For this…
A new series of sulfobetaine surfactants with double-chain single-head structure were derived from 1,3-dialkyl glyceryl ethers and their performances in reducing Daqing crude oil/connate water interfacial tension (IFT) in the absence of alkali were…
The effects of alkalis on the dynamic interfacial tensions (IFTs) of two betaine solutions with different hydrophilic parts, erucyl dimethyl amidopropyl carboxybetaine (EDAC) and erucyl dimethyl amidopropyl sulfobetaine (EDAS), against crude oil and…
In this article, we have investigated interfacial tensions (IFTs) of anionic-nonionic surfactant fatty alcohol polyoxyethanol carboxylate (CnEOmC) and their mixed solutions against n-alkanes, crude oil and model oils containing crude oil fractions,…
To clarify the mechanism responsible for the reduction of interfacial tension (IFT), the dynamic and equilibrium IFTs of different betaine solutions against n-alkanes, kerosene, heavy oil fractions model oil and crude oil have been investigated by…
Hydrocarbon gas flooding/Huff-n-Puff (HNP) can improve the oil recovery in the unconventional reservoirs. Here, the mechanisms accounting for fluid flow in the low-permeability and ultra-low permeability reservoirs were experimentally and…
