Assessing the Biological Inhibitors Effect on Crude Oil Wax Appearance Temperature Reduction [PDF]

Journal of Petroleum Science and Technology, 2018
To assess the effect of micro-organisms on the reduction of wax appearance temperature (WAT) of waxy crude oil, some appropriate strains were obtained from contaminated samples exposed to hydrocarbon compounds for a long time.

Influence of shear on rheology of the crude oil treated by flow improver

Energy Reports, 2019
Because the influence of shear on the rheology of waxy crude oil must be considered according to the composition and structure of the waxy crude oil transported via pipeline when a new pipeline is constructed, the risks associated with changes in the ...

Investigation of adsorption behaviors of paraffin waxes on iron, iron oxide, and iron III oxide pipeline's internal surfaces using adsorption locator model

Petroleum Research, 2022
Wax deposition in pipelines leads to pressure drop, reduced effective cross-sectional area, and blockages. Although mathematical models and experimental loops were used to model wax precipitation on pipeline surfaces, its prediction at molecular levels ...

A new approach to improving efficiency of gas-lift wells in the conditions of the formation of organic wax deposits in the Dragon field

Journal of Petroleum Exploration and Production Technology, 2020
Gas-lift is one of the artificial methods in which gas is injected down the production casing–tubing annulus and enters the production tubing through a number of gas-lift valves. During the production of a gas-lift well, the injected compressed gas might
