A molecular modified polyacrylamide with Gemini surfactant monomers, named as HA1, was
evaluated in this paper as an alternative to enhance the offshore heavy oil recovery. The …

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 …

Most of oilfields have entered the development stage of high water-cut and low recovery
factors, and stabilizing oil production and controlling water production are the key to …

The two-phase viscosity modifier (T-PVM) is a new chemical agent for enhancing sweep and
displacement efficiency in heavy oil reservoirs due to multiple-effects of reducing oil viscosity …

The continuous growth in global energy and chemical raw material demand has drawn
significant attention to the development of heavy oil resources. A primary challenge in heavy …

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 …

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 …

Tight reservoirs are considered one of the unconventional hydrocarbon reservoirs with low
permeability and porosity, directly affecting the oil production rate rather than conventional …

In order to comprehensively comprehend the distinctions in solution properties,
emulsification characteristics, and oil displacement efficiency between polymeric surfactant …

Surfactant-polymer (SP) flooding has been regarded as an efficient technique for enhanced
oil recovery in the development of mature oil fields, especially for those with heterogeneous …
