Asphaltene deposition in the reservoirs, tubbing, and surface facilities causes serious flow
assurance problems with significant economic implications. Asphaltene flow assurance …

Bitumen, one of the by-products of petroleum industry processes, is the most common binder
used in road pavements and in the construction industry in general. It is a complex organic …

Previously, asphaltene science had been hindered by many significant uncertainties
regarding molecular weight, molecular structure, and nanocolloidal characteristics in …

Many reservoirs worldwide received separate charges of primary biogenic gas and oil. In
high pressure provinces such as the Gulf of Mexico, the added gas should be in solution if …

Unbiased analysis of asphaltene molecules by mass spectrometry requires that the three
fundamental steps in mass spectrometry-volatilization, ionization, and mass analysis-are …

Asphaltene precipitation and subsequent deposition is a potential flow assurance problem
for the oil industry nowadays. Moreover, because oil production is moving to more difficult …

Fluid distributions throughout oilfield reservoirs have been measured with increasing
accuracy and coverage, both vertical and laterally, in recent years. Currently, a routine …

In this work, the factors affecting asphaltenes deposition in high-temperature and high-
pressure wells were studied using backscattered light and PVT equipment customized to …

Recently, global attraction has shifted toward heavy unconventional crude oil due to the
depletion of light oil resources. Generally, heavy crude oils are highly viscous in nature; due …

Previous studies have shown that the application of a high-voltage electric field to a liquid or
gelled waxy crude oil can significantly improve its cold flowability, such as reducing viscosity …
