With the development of the oil industry, improving oil recovery (IOR) technology is
becoming more and more important, and an excellent working fluid is a key to IOR. Among …

With a constant upsurge in energy demand, production from depleted and harsh reservoirs
through enhanced oil recovery techniques (EOR) has significantly increased. Among many …

Managing and remediating perfluoroalkyl and polyfluoroalkyl substance (PFAS)
contaminated sites remains challenging. The major reasons are the complexity of geological …

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

The investigation of tight oil reservoirs has become a significant area of interest in
unconventional oil development. CO 2 flooding is considered an effective oil recovery …

Drainage displacement at unfavorable viscosity ratios is often encountered in oil recovery,
CO2 sequestration, and NAPL remediation, which significantly limits recovery of fluids from …

Wettability alteration of the porous medium from oil-wet (OW) to neutral-wet or even water-
wet (WW) is proposed as one of the main mechanisms behind the enhanced oil recovery …

A novel concept of utilizing nanoparticles (NPs) to boost oil recovery and reduce entrapped
oil in hydrocarbon reservoirs is being explored. The use of nanofluids (NFs) flooding to …

This paper experimentally investigates how adding nanoparticles to Soloterra surfactant
affects phase behavior and surfactant flooding. These experiments include three phases. In …

Due to the problem of low formation pressure in shale oil reservoirs of the Ordos Basin, oil
production decreases rapidly during primary production stage. It is crucial to maintain …
