Modeling of wax precipitation [PDF]
, 2007 Thesis (M.S.) University of Alaska Fairbanks, 2007Due to increasing oil demand, oil companies are moving into deep water and arctic environments for oil production. In these regions, due to lower temperature, wax starts depositing when the temperature in

Heat transfer computation for crude oil flow along pipeline [PDF]
, 2014 The waxes that present in most crude oils include n-alkanes, iso-alkanes, alkyl cyclic compounds and alkyl aromatic. The amount of wax contained in the crude oil sample varies.

Effect of asphaltenes on crude oil wax crystallization
, 2005 The paper summarizes the experimental work done on asphaltene influenced wax crystallization. Three different asphaltenes (from stable oil, instable oil, and deposit) were mixed at several concentrations or dispersions into the waxy crude oil.

Evaluation of effects of selected wax inhibitors on wax appearance and disappearance temperatures
, 2009 [[abstract]]©2003 Taylor & Francis - In this investigation, a light transmittance method was used to evaluate the wax appearance temperatures (WAT) and wax disappearance temperatures (WDT) of model paraffin compounds (n-C24H50 (C-24) and n-C36H74 (C-36))

Analytical and Numerical Modeling of Paraffin Wax in Pipelines [PDF]
, 2013 Paraffin wax deposition, or the settling of solid wax particles on pipelines and equipment, is an extensive problem encountered in oil production and transportation. Flowing through subsea pipelines, oil and condensate are subject to cooling.

, 2017 ACLInternational audienceAmong the flow assurance subjects, wax deposition plays a major role. As exploration an oil production moves towards deeper water frontiers, longer tiebacks increase the risk of wax deposition, which is assessed through modeling.

, 2016 Temperature sensitivity of waxy crude oils makes it difficult to study their flow behaviour in the presence of water especially near their wax appearance temperature (WAT). In this study a method was proposed and implemented to mitigate such difficulties
