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 …

It has become a well-known fact that finding sustainable solutions to the unavoidable high
pressure losses accompanying pipeline flows to increase the pumping capacity without …

In this study the effect of the presence of a drag reducing agent (DRA) on the pressure drop
in cocurrent horizontal pipes carrying slug two-phase flow of air and crude oil is investigated …

Measurements of drag-reduction are presented for oil–water flowing in a horizontal 0.0254
m pipe. Different oil–water configurations were observed. The injection of water soluble …

A literature survey of the published work on drag reduction by Drag Reducing Agent (DRA)
in two-phase flow is reviewed. Characteristics of the two-phase flow with drag reducing …

Precise prediction of the gas–liquid slug flow is crucial for proper design and operation at
various industrial processes. This paper provides a comprehensive review of published …

High-molecular-weight partially hydrolyzed polyacrylamides are widely used in enhanced
oil recovery. Mechanical degradation of these polymers as a result of flow through pumps …

The effect of a drag-reducing polymer (DRP) in the water phase during horizontal oil–water
flow was investigated in a 14 mm ID acrylic pipe. Oil (5.5 mPa s, 828 kg/m3) and a co …

Several decades following Tom's discoveries on polymeric drag reducing agents (DRA)
continue to see research efforts to produce robust and shear-stable DRA. Most efforts …

The conventional mainstream method of polymer additives for reducing drag in pipes is
disadvantageous from certain environmental perspectives. This paper aims to go against the …
