In this work, NiFe nanocatalysts with different molar ratios 1:0.33, 1:1 and 1:3 were synthesized by a modified inverse microemulsion method at Soft Chemistry conditions in order to apply them to heavy crude oil (HCO) in situ hydroprocessing and to…
In this paper, phase behavior in temperature scanning of E1305/distillate fractions/water/n-butyl alcohol microemulsion system were investigated. And the effect of surfactant concentration and oil type on microemulsion solubilization ability was…
In this work, nanocatalysts as Ni, Mo, Fe nanoparticles (NPs) were synthesized by the modified inverse microemulsion method at room temperature conditions in order to apply them to heavy crude oil (HCO) in situ hydroprocessing and to improve their…
Sodium dodecyl benzene sulfonate (SDBS) was used as a surfactant to prepare microemulsion for emergency treatment of crude oil contaminated soil and recovery of crude oil. Comparison between the original and the recovered crude oil and soil samples…
Microemulsions and aqueous solution were prepared using biosurfactant sophorolipid, and treatment and crude oil recovery simulation experiments on oily soil were carried out. By comparison, the results showed that the effect of micro-emulsion of…
The removal of crude oil in saline water from microemulsion by cotton linter fiber was investigated by batch sorption. The experimental sorption data were collected without changing the water pH, biosorbent dosage (0.5g/L), or medium rotation…
Tight oil reservoirs typically have an estimated ultimate recovery of less than 10% after hydraulic fracturing, where enhanced oil recovery (EOR) technique is needed. Comparing to the gas-EOR, the surfactant-EOR neither alters the current fracturing…
Combinations of surfactant-polymer (SP) and alkali-surfactant-polymer (ASP) have proven, in the laboratory and the field, to be good methods for enhanced oil recovery (EOR). However, field implementation of these methods has not been widely…
The primary mechanism of surfactant enhanced oil recovery (EOR) has always been ascribed to ultralow interfacial tension (IFT) between oil and dispalcing fluid by forming middle-phase microemulsion. However, it is found in field trials that oil can…

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 sustainable power sources, oil and gas industry stays as the world’s…
In this review, an attempt has been taken to show the preferential selection criteria of microemulsions and nanoemulsions for applications in enhanced oil recovery. This paper primarily explains the preparation, characterization, and interaction…
