Hydrate technology is of considerable significance for industrial natural gas storage and transportation. In this paper, the hydrate formation in surfactants with different ratios of alkyl glycosides (APG) and sodium dodecyl sulfate (SDS) was studied…
Crude oil leakage during production, transportation and storage has polluted large soil areas. If improperly treated, this could seriously threaten human health. In this study, low-permeability soil was selected as the contaminated target because it…
Storage and transportation of natural gas in the form of hydrate attract interest in recent times as a huge amount of gas can be accumulated within a small volume of solid hydrate. In the present study, a novel surfactant synthesized from castor oil…
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 efficiency of herbicide applications in agriculture is dependent not only on the toxicity or biological action of active substances on weeds, but also the solubility, volatilization, adherence, penetration, rainfastness, foaming, and drift of the…
The foam performance in the presence of oil plays an essential role in foam application in enhancing oil recovery. This study systematically investigated whey protein isolate (WPI), the effectiveness of foam generation, the effect of three types of…
Surfactant and foam processes have been widely used to enhance oil recovery from petroleum-bearing geological formations, and also been recently extended to remediate non-aqueous-phase-liquid (NAPL) contaminants from the shallow subsurface. This…
Improved oil recovery (IOR) includes enhanced oil recovery (EOR) and other technologies (i.e. fracturing, water injection optimization, etc.), have become important methods to increase the oil/gas production in petroleum industry. However,…
Electrocoalescence is widely used to separate water from crude oil in petroleum industry. However, the electric field often forces water droplets distributed in chain shape, thus improving the danger of short circuit by bridging electrodes. To…
A sequential process of electrokinetic soil flushing (EKSF) and landfarming treatment was demonstrated to remove hydrocarbons from clay soil. Surfactant concentration was the independent variable with a concentration of 2×, 4×, 6×, and 8× of critical…
The surfactant phase behavior laboratory test for chemical enhanced oil recovery (EOR) formulation design is time consuming. However, it is possible to use computational chemistry simulation to minimize the duration. The only known non-empirical…
Oil leakage, which is inevitable in the process of extraction, processing, transportation and storage, seriously undermines the soil and groundwater environment. Surfactants can facilitate the migration and solution of oil contaminants from…
Single-step nanofluids have shown better stability and size control properties than conventional two-step nanofluids under similar conditions. However, for wide-spread oilfield acceptance, there is a need to investigate the role of oilfield…
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…
Surfactant-based technologies have been studied for the treatment of radioactive waste containing isotopes of radium. Nevertheless, the use of combined processes to remove radium from radioactive oil sludge is scarce in the literature. The objective…
Improved oil recovery (IOR) includes enhanced oil recovery (EOR) and other technologies (i.e. fracturing, water injection optimization, etc.), have become important methods to increase the oil/gas production in petroleum industry. However,…
In order to ensure the emulsification function of chemical flooding and simultaneously relieve the difficulty in demulsification of produced fluid in heavy oilfield, a pH-responsive surfactant HB-HA− (4-hydroxybenzaldehyde (HB) and n-hexylamine (HA))…
Surfactant-stabilized CO2 foam is a promising technique to increase an oil reservoir’s sweep efficiency and therefore produce more oil. The development of successful CO2 foam formulations requires extensive screening and development of commercially…
Hypothesis. A large number of papers discuss merits and mechanisms of low salinity waterflooding. For each mechanism proposed, there are counter examples to invalidate the stated mechanism. The effect of wettability from low salinity water, which is…
The stability and viscosity of W/O emulsions and their application for heavy oil pipeline transportation were investigated using two Iranian crude oil samples. An Iranian heavy crude oil sample named West Paydar and a blend of diesel and bitumen were…
The area of oil foams although important industrially has received little academic attention until the last decade. The early work using molecular surfactants for stabilisation was limited and as such it is difficult to obtain general rules of thumb.…
Soapnuts and other saponin-rich plant materials are known for their phytochemistry and pharmacology. After a gap of two decades, there has been a sudden spate in research on soapnuts with experiments on a wide range of applications. The present…
