This review discusses the application of emulsified acids for oil well stimulation. Types of oil,
aqueous solutions, and emulsifiers are discussed in detail along with the solid agents and …

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

Both the academic society and the industry are hunting for new energy forms for the future.
However, the world should not forget the conventional technologies that contribute to the …

Friction drag is a nonnegligible matter when relative motion happens between solid and
liquid phase, which brings many inconveniences in ship navigation, fluid transportation …

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 …

An accurate determination of the pressure gradient is required for efficient designing of oil
and gas wells and pipe systems. Despite the recent improvements in accuracy of models …

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 …

Drag reduction phenomenon in pipelines has received lots of attention during the past
decades due to its potential engineering applications, especially in fluid transporting …

The effect of adding a drag reducing polymer in the water phase during horizontal oil–water
flows was studied experimentally. Experiments were carried out in a 14 mm ID acrylic pipe …
