In this paper, recent advances in surfactant enhanced oil recovery (EOR) are reviewed. The
addition of alkali to surfactant flooding in the 1980s reduced the amount of surfactant …

The trend of growing interest in alternative source of energy focuses on renewable products
worldwide. However, the situation of petroleum industries in many countries needs much …

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 …

Surfactants play a vital role in chemical enhanced oil recovery (cEOR). The amount of
surfactant loss caused by retention during flooding through reservoir rock is still a challenge …

We report results for a number of promising enhanced-oil-recovery (EOR) surfactants based
upon a fast, low-cost laboratory screening process that is highly effective in selecting the …

We describe a three-dimensional, multicomponent, multiphase compositional finite-
difference simulator for application to the analysis of contaminant transport and surfactant …

By tracking and analyzing the research and practices of chemical flooding carried out in the
Daqing Oilfield, NE China since the 1970s, the chemical flooding theory, technology …

The worldwide demand of energy sources is increasing day by day. The trend of growing
interest on renewable products is also increasing widely. Regardless of the advances of …

Many crude oil candidates for enhanced oil recovery by alkaline flooding produce their
lowest interfacial tension at very low concentrations of alkali. Alkaline consumption by the …

Hypothesis It is generally believed that the improved efficiency of surfactant enhanced oil
recovery (EOR) comes from ultra-low interfacial tension (IFT) between oil and surfactant …
