Wax deposition and gel formation have been crucial problems to the oil industries. The
deposition of waxes would lead to gelation which blocks flow in pipelines and interrupts …

Yield stress fluid flows occur in a great many operations and unit processes within the oil
and gas industry. This paper reviews this usage within reservoir flows of heavy oil, drilling …

A fundamental study of the deposition and aging of a thin incipient wax‐oil gel that is formed
during the flow of waxy oils in cooled pipes was performed. The solubility of high molecular …

Deposition of high molecular weight paraffins on the inner wall of subsea production and
transportation pipelines continues to be a critical operational problem faced by the …

High molecular weight paraffins are known to form gels of complex morphology at low
temperatures due to the low solubility of these compounds in aromatic or naphthene-base …

The phase stability of crude oil is dependent on a multitude of factors, including temperature,
pressure, and component fractions, especially long chain paraffin and polar asphaltene …

Wax deposition in oil subsea pipeline systems is a big challenge in petroleum industry due
to the frigid temperature of pipe walls that influences crystallization and wax deposition on …

Asphaltenes, as the heaviest and most polar fraction of petroleum, have been characterized
by various analytical techniques. A variety of fractionation methods have been carried out to …

In the oil pipeline transportation system, wax deposition will reduce the effective circulation
area, weaken the overall pipeline transportation capacity, and even block the pipeline …

Predicting an accurate startup pressure for gelled waxy crude oils in pipelines is an old
challenge yet to be overcome. It is known that the conventional force balance grossly …
