In this work, Fe2O3, ZnO, and MgO nanoparticles were synthesized via a chemical precipitation method to investigate their effects on wax formation, morphological characteristics, and rheological behavior in a crude oil sample. For this purpose,…
In the process of CO2 geological sequestration, there is a risk that CO2 will leak into groundwater, resulting in a series of physical and chemical reactions, with influence on chemical compositions of groundwater. In this work, numerical simulation…
The ability of both bare and surface-modified hematite nanoparticles to reduce the viscosity and upgrade the quality of heavy crude oil via aquathermolysis reaction was investigated in this study. The surface of hematite nanoparticles was modified…
Oil-dispersed -Fe2O3 nanocatalysts were prepared by coating -Fe2O3 nanoparticles with oleic acid (OA). Mossbauer spectroscopy, X-ray diffraction, and field emission scanning electron microscopy were used to characterize -Fe2O3 and -Fe2O3@OA. Their…
Abstract: Asphaltene is the heaviest organic compound in crude oils that its precipitation and deposition cause many negative effects on oil production such as an overall decrease in production rate and an increase in operating costs. Nanoparticle…
This study aims to investigate a new method of combining ultrasonic waves with different frequencies and magnetic nanoparticles in reducing the asphaltene content and kinematic viscosity of heavy oil. In general, the experiments included irradiation…
The Fiber Bragg grating (FBG) sensor used for distinguishing the oil movement offers detailed insights about the reservoir oil and is the key to quantifying the impact on improvement and the integrity and efficiency of the wells. The modified FBG…
In this paper the local materials used in concrete mix are studied in a manner that they can resist the aggressive marine environment and mechanical damage, which can occur at several stages during transportation, construction and installation of the…
