252 literature sources and about 5000 crude oil assays were reviewed in this work. The
review has shown that the petroleum characterization can be classified in three categories …

Industrial extraction of unconventional petroleum results in notable volumes of oil sands
process water (OSPW), containing elevated concentrations of naphthenic acids (NAs). The …

The developments of high-resolution mass spectrometry and soft ionization technologies
have enabled the molecular characterization of petroleum fractions. However, quantitative …

The petroleum wastewater (PWW) contains a diverse range of recalcitrant organic
contaminants. Of particular concern is the removal of naphthenic acids (NAs) due to the high …

Water flooding can create a transient heating effect that causes oil and water to self-emulsify.
This study sought to understand how this effect impacts crude oil's emulsifying properties by …

Oil sludge deposition is a common phenomenon during oil transportation, storage, and
processing. Detailed molecular characterization of sludges is a prerequisite for …

Heavy oil is one of the most significant unconventional petroleum resources and one of its
formation mechanisms is biodegradation. The characterization of the molecular …

The characterization of naphthenic acids (NAs) in petroleum samples has received
particular attention and is still an analytical challenge as a result of the complexity of the …

The determination of the total acid number (TAN) of crude oils is of great importance in the
petroleum refining industry for evaluating the corrosion potentials of oils. The presence of …

The adsorption of naphthenic acids (NAs) on clay surfaces induces an increase in surface
hydrophobicity, which is detrimental to crude oil recovery and froth quality. Sodium citrate …
