After long-term water injection, mature reservoirs are encountered with the adverse
consequences of the treatment, including erosion, rock formation destruction and drastic …

In recent years, polymer micro/nanogels which are re-crosslinked polymers with 3D
networks, have attracted a lot of interest in Enhanced Oil Recovery (EOR) field. In size of …

Nitrogen foam flooding is a promising technique for enhanced oil recovery, but instability of
the foam limits its application. In this article, partially hydrophobic modified SiO2 …

Hydrogels are ideal substrates for interfacial solar steam evaporation because of their
tunable water evaporation enthalpy. However, conventional hydrogel-based evaporators …

Carbon capture and storage (CCS) technology has been widely investigated to decrease
the greenhouse effect. Geological CO2 storage sites are targeted mainly on depleted …

Hydrogels hold promise in agriculture as reservoirs of water in dry soil, potentially alleviating
the burden of irrigation. However, confinement in soil can markedly reduce the ability of …

A gel system has been widely used in many mature oilfields for water shut-off treatment. In
the present study, the hydrophobically associating polymer (HAP) was cross-linked with the …

The current study aims at in-depth profile control to further improve oil recovery by studying
the matching relationship between the size of dispersed particle gel (DPG) and geometry of …

Heterogeneity is well known to reduce sweep efficiency during oil development processes.
Self-adaptive micro gel (SMG) as a agent for in-depth profile control is significantly limited to …

An anionic–nonionic surfactant was proposed as viscosity reducer (VR) for study. Firstly,
bulk emulsion behavior was investigated to optimize the emulsification process. Secondly …
