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 …

Surfactants have been widely used in many industrial products such as detergents,
medicines, and anti-corrosive treatments due to their unique structures consisted of two …

Since conventional oil recovery techniques only produce a limited fraction of the original oil
in place (OOIP), the need for Enhanced Oil Recovery (EOR) methods has become …

A new phosphorus/nitrogen flame retardant (FR) containing reactive–P–O− NH4+ groups
was synthesized from glycerol, phosphoric acid, and urea. At high temperatures, the–P–O …

Surfactants increase the capillary number and resultantly pore-scale displacement efficiency
by lowering interfacial tension (IFT) and changing wettability of the rock. However …

The critical micelle concentration (CMC) is one main parameter of surfactants, so an
accurate, rapid, and convenient method for CMC determination is of great significance for …

To facilitate the understanding of the intrinsic mechanism responsible for the IFTs of betaine
solutions, partly hydrolyzed polyacrylamide (HPAM) and hydrophobically modified …

Aiming at improving the thermal stability of CO 2 foam under reservoir conditions, four
different types of surfactants were evaluated through high temperature and pressure …

One of the major challenges for the oil industry in the 21st century is to get the desired
surfactants that are soluble in high saline water (220, 000 ppm) and stable at high …

In the present study, a series of biobased anionic-nonionic surfactants were used to
evaluate their physicochemical properties for predicting the effectiveness in chemical …
