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 …

Enhanced oil recovery (EOR) processes have a great potential to maximize oil recovery
factor of the existing reservoirs, where a significant volume of the unrecovered oil after …

Surfactant flooding is an important technique used in enhanced oil recovery to reduce the
amount of oil in pore space of matrix rock. Surfactants are injected to mobilize residual oil by …

With the increasing demand for efficient extraction of residual oil, enhanced oil recovery
(EOR) offers prospects for producing more reservoirs' original oil in place. As one of the most …

Polymer flooding is one of the most promising techniques for the recovery of remaining oil
from light oil reservoirs. Water soluble polymers are used to enhance the viscosity of …

Injecting surfactant by means of chemical enhanced oil recovery (cEOR) has acquired
predominant attention in improving oil recovery by changing either fluid/rock and/or …

Gemini surfactants are a group of novel surfactants with more than one hydrophilic head
group and hydrophobic tail group linked by a spacer at or near the head groups. Unique …

Surfactant injection into a depleted hydrocarbon reservoir is one of the ways to reduce
residual oil saturation, thereby enhancing crude oil production. However, surfactants …

Most oil fields today are mature, and the majority of the reservoirs in the Middle East are
carbonate rocks characterized by high temperature high salinity (HTHS), heterogeneous …

Nanofluids offer many advantages over surfactant and polymer solutions during enhanced
oil recovery (EOR). This review discusses the current state and future prospects of …
