Chemical enhanced oil recovery (CEOR) is a well-recognized technique for exploiting the
original oil in place (OOIP) left behind in subsurface petroleum reservoirs after primary and …

This review discusses surfactants used for chemical flooding, including surfactant-polymer
flooding and alkali-surfactant-polymer flooding. The review, unlike most previous reviews in …

Nanoparticles-assisted polymer flooding has attracted the attention of researchers for its
enhanced rheological properties and stability of the chemical slugs. The present work deals …

Mixed cationic/anionic surfactant systems have showed great potential in various fields.
Ionic liquids with extraordinary physical and chemical properties are regarded as novel …

Steam flooding and chemical flooding have been widely proven to be the most promising
methods to facilitate the development of heavy oil reservoirs. However, the remaining oil …

Enhanced oil recovery (EOR) is one of the most important branches of petroleum
engineering. For this purpose, the surfactant flooding method remains one of the primary …

Steam flooding is an important method for the development of heavy oil reservoirs, but
steam channeling is an inevitable serious problem in the process of steam injection, which …

Interfacial tension (IFT) and wettability are the two major factors influencing oil recovery. The
synergistic effect of low salinity water (LSW) with chemical agents such as surfactants …

Steam-assisted gravity drainage (SAGD) has been widely proven to enhance heavy oil
recovery effectively. However, the performance evaluation of SAGD in heavy oil reservoirs …

The synergistic effects of surfactant–polymer (SP) flooding under high-temperature and high-
salinity (HTHS) conditions were investigated for a hydrophobically associating …
