The current and prospective worldwide energy demands have led either to start exploiting
the more difficult and costly unconventional oil reserves, or to maximize the exploitation of …

Chemical-enhanced oil recovery (cEOR) is a class of techniques commonly used to extract
hydrocarbon fluids from reservoir rocks beyond conventional waterflooding. Surfactants are …

A significant amount of oil (ie 60–70%) remains trapped in reservoirs after the conventional
primary and secondary methods of oil recovery. Enhanced oil recovery (EOR) methods are …

Strong foam can be generated in porous media containing oil, resulting in incremental oil
recovery; however, oil recovery factor is restricted. A large fraction of oil recovered by foam …

For investigating the types and formation mechanisms of residual oil after surfactant
imbibition, the easy-emulsifying surfactant Sodium Dodecylbenzene Sulfonate (SDBS) and …

Well stimulation and enhanced oil recovery (EOR) plays an important role in oil production.
Microemulsions and nanoemulsions fluids have been studied as a fluid to enhance the …

Nanoemulsions are small droplet-sized systems that have low surface tension and a small
percentage of active material in their composition. In this study, low oil content …

One of the main reasons for foam flooding enhanced oil recovery (EOR) is mobilizing oil left
in the reservoir after primary recovery (depletion by pressure difference solely) and water …

The objective of this study is to discover a synergistic effect between foam stability in bulk
and micro-emulsion phase behaviour to design a high-performance chemical system for an …

A novel formula of anionic surfactants with propoxy (PO) and ethoxy (EO) groups and
cationic surfactants was developed and temperature and salt resistance performance of the …
