Currently, there is a widespread interest in the different methods of chemical enhanced oil
recovery (EOR) as a result of the continuous decline in the conventional oil reserves and the …

Due to the continuous depletion of crude oils in the reserves, and continuous rise in energy
demand, there is currently a widespread interest in various methods of chemical enhanced …

In the petroleum industry, oil and water emulsions are frequent, not only in oilfield operations
but also during the transportation and refining processes. Once depicting emulsion …

Heavy oil exploitation needs efficient viscosity reducers to reduce viscosity, and polyether
carboxylate viscosity reducers have a significant viscosity reduction effect on heavy oil …

The sulfobetaine and sulfonate surfactants derived from 1, 3-dialkyl glyceryl ethers were
examined as surfactants for enhanced oil recovery free of alkali in high salinity and high …

The synthesis of sulfobetaine surfactants and their application in tertiary oil recovery (TOR)
are summarized in this paper. The synthesis of sulfobetaine surfactants was classified into …

Thermal stability, salt tolerance, and solubility in normal and high salinity brine are the major
requirements for any surfactant designed for oilfield applications because the surfactant …

Surfactants with stable chemical structures and robust ability are required to lower interfacial
tension and stabilize emulsions for successful chemical injection applications. This work …

Surfactants have been used to increase hydrocarbon recovery to meet the increasing
demand for oil and gas. This mechanism of using surfactants reduces the Interfacial Tension …

The chemical flooding is one of the major enhanced oil recovery (EOR) methods for
recovering residual oil within the pores of rock. However, the injected chemical such as …
