Water-soluble polymers with high molecular weights are known to decrease the frictional
drag in turbulent flow very effectively at concentrations of tens or hundreds of ppm. This drag …

Increasing the flow capacity and pum** rates is challenging in petroleum production
systems due to drag or frictional losses. Drag-reducing agents (DRAs) are usually added to …

The development of advanced anti-salt drag reduction (DR) agents is crucial for enhancing
oil recovery rates, particularly in highly mineralized saline water where the network structure …

Water-soluble polymers as drag reducers have been widely utilized in slick-water for
fracturing shale oil and gas reservoirs. However, the low viscosity characteristics, high …

Water-based fracturing fluids are widely used in hydraulic fracturing to stimulate reservoirs.
However, a novel fracturing fluid system needs to be developed for use in complex and …

Water-soluble polymers have been used as drag reducer in slick-water hydrofracking for
unconventional hydrocarbons, however, the fatal “thermothinning” behavior and weak salt …

To develop high-salinity, high-temperature reservoirs, a novel supramolecular viscoelastic
polymer-based fracturing fluid modified with an amphiphilic functional monomer was …

Flow and heat transfer characteristics of xanthan gum (XG) solutions are experimentally
studied to compare the drag reduction (DR) and heat transfer reduction (HTR) behavior in …

The effect of molecular weight distribution of polyacrylamide (PAAm) on drag reduction was
studied in two flow geometries. Commercial PAAm with different weight averaged molecular …

In this paper, a slick water drag reducer with excellent drag reduction and a simple
molecular structure, called QIE-0, was prepared by inverse emulsion copolymerization. QIE …
