association equation of statechemical compressibility factorcoprecipitationresinResin content is an effective parameter that has adverse effect on precipitation of asphaltene in crude oil. Fluctuations in temperature, pressure, or oil composition disturb the chemical equilibrium in a reservoir, which results ...
The typical flow curves for these oil types have been plotted. It has been detected that these oils are non-Newtonian fluids, viscosity of which is dependent on shear rate. Based on Arrhenius-Eyring equation, calculations of viscous flow activation energy and complex structural unit (CSU) sizes...
Accordingly, enhanced oil recovery (EOR) approaches have been adopted to recover more crude oil. One of the common EOR (i.e., tertiary oil recovery) methods is chemical flooding. The formation of crude oil-in-water (crude O/W) emulsions is one of the key mechanisms in enhancing the ...

The injection of low-salinity brine enhances oil recovery by altering the mineral wettability in carbonate reservoirs. However, the reported effectiveness of low-salinity water varies significantly in the literature, and the underlying mechanism of wettability alteration is controversial. In this work, we...
Crude Oil Pretreatment Systems preserve the integrity of downstream equipment and comply with regulatory standards while making a substantial contribution to the manufacture of refined products of superior quality via the use of a mix of physical, chemical, and cutting-edge technical processes. The ...
In this paper, the rheological properties and viscosity reduction mechanism of waxy crude oil were reviewed. Firstly, the rheological behavior of waxy crud
Backgrounds and Objectives: Oil pollution can be generated as a result of spillage, leakage, discharge, exploration, production, refining, transport and storage of crude oil and fuels in the environment. Consequently, many researchers have developed and studied the chemical, physical and biological ...
The partition coefficients, Kd, of the different samples are correlated with the clay and water contents in the soil, were the multiparametric equation obtained had a satisfactory predictive value. On the other hand, the data obtained with the different oil fractions are consistent with competitive ...
paper, the measurement of oil price volatility (OVt) refers to the latest research of Phan et al. (2019) and Maghyereh and Abdoh (2020). In short, the standard deviation of daily returns of oil prices is adopted as the calculation basis of oil price uncertainty. The equation is as ...
