  • Can polyacrylic acid reduce crude oil drag?
  • Using a loop circulation system with a 5 m long stainless steel pipe with an inner diameter of 0.0508 m, Rashid et al. (2019) employed Poly Acrylic Acid (PAA) as a DRA to lower the drag of crude oil (viscosity is 27.55 cP at 25 °C) at various concentrations (50, 100, 150, 200, and 250 ppm).
  • What is a drag reducing agent?
  • Drag reduction is required to increase the flow capacity and pumping rate, and drag-reducing agents (DRAs) are usually added to the fluids to reduce the drag. DRAs are defined as additives that are added to the fluids to reduce the drag on the pipe wall.
  • What is drag reduction in drilling fluid system?
  • DRAs (friction reducers) are one of the essential components of the drilling fluid system. The drag reduction induced by DRA makes it possible to inject the drilling fluid at the high injection rate required for efficient hole cleaning with limited pump capacity. It also helps in maintaining the pumping equipment and flowlines associated with it.
  • Which additive has the highest drag reduction?
  • The highest drag reduction was about 41% for FLO FUSION 3000, which performed better than the other additives using 250 ppm at 35 °C and a Reynolds number of 12,000. With a concentration of 400 ppm at 35 °C and a Reynolds number of 12,000, copolymers B5 and B6 showed greater drag reduction values of 36.5% and 36.28%, respectively.
