Microemulsions, as thermodynamically stable mixtures of oil, water, and surfactant, are
known and have been studied for more than 70 years. However, even today there are still …

Surfactant-based oil recovery processes are employed to lower the interfacial tension in
immiscible displacement processes, change the wettability of rock to a more water-wet …

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 …

Changing oil-wet surfaces toward higher water wettability is of key importance in subsurface
engineering applications. This includes petroleum recovery from fractured limestone …

Oil production from matured crude oil reservoirs is still associated with low recovery factors.
Chemical enhanced oil recovery (EOR) is one of the techniques which can significantly …

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 …

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

This study is one of very few dealing with the distribution and the origin of heavy metals in
French soils from a priori non-polluted forest areas. The abundance of heavy metals …

Controlling nanofluid stability in saline environment has been a long-standing challenge as
salt ions screen-out the surface charge of the nanoparticles (NPs), rendering them unstable …
