drag reduction in single-phase crude oil flow: a mini-review

Drag reduction in single-phase crude oil flow: A mini-review

1. Introduction The transfer of crude oil by pipeline is very important to the world economy. In recent decades, the high growth in global crude oil consumption has posed problems for oil transportation due to the increase in energy loss from turbulent flows. The primary source of fluid energy loss in pipeline transport is frictional resistance.

perspective review of polymers as additives in water-based

Perspective Review of Polymers as Additives in Water-Based

After successful implementation for more than 6 decades by the oil and gas industry, hydraulic fracturing remains the pioneer well stimulation method to date. Polymers are one of the additives in fracturing fluids that play a significant role. Polymers are used as friction reducers and viscosifiers to provide a transport medium for proppants in fracturing fluids. There are many polymer-based

parameters of drag reducing polymers and drag reduction

Parameters of Drag Reducing Polymers and Drag Reduction

While the drag reduction at the plateau value increases with polymer molecular weight, the maximum drag reduction was not affected by the increase in polymer charge density up to 13%. For instance, the maximum drag reduction for anionic polymers with molecular weight 6¨C8 million Da. and charge density between 5 and 13% was around 60%, which

mechanistic study of drag reduction in turbulent pipeline

Mechanistic study of drag reduction in turbulent pipeline

The mixed aqueous solutions of anionic surfactant sodium dodecyl sulfate with polymer polyacrylamide of various kinds, i.e., cationic, anionic, nonionic, and zwitterion, were firstly tested to study their synergistic effect on drag reduction performance. The optimal combination of sodium dodecyl sulfate with anionic polyacrylamide was confirmed due to their strong hydrophobic interaction and
