The transportation of heavy and extra-heavy crude oils from the head-well to the refinery is
becoming important since their production is currently rising all over the world. Such oils are …

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 …

Modern production methods and environmental constraints demand chemical solutions. And
as oilfields age, the need for chemicals to ensure steady production increases. Production …

Gas–liquid two-phase flows through long pipelines are one of the most common cases
found in chemical, oil, and gas industries. In contrast to the gas/Newtonian liquid systems …

In this study, the effects of various parameters on pressure drop reduction caused by adding
small amounts of drag reducing polymers has been investigated in crude oil pipelines. In …

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 …

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 …
