Reducing Agent

Definition - What does Reducing Agent mean?

A Reducing Agent is a substance that loses or gives up electrons in a chemical reaction. When a reducing agent gives up an electron, it is considered to be oxidized. The atom where the reducing agent sends its electron is called the oxidant. Reducing agents are added to acids during enhanced oil recovery practices so as to stabilize the iron content or reduce the iron atoms (Fe+3 & Fe+2). The stabilization of the iron content helps in avoiding precipitation.

Petropedia explains Reducing Agent

In the oil industry, the primary responsibility is to increase the production of crude oil from a reservoir and transport it to the destination without any wastage. However, due to the viscous nature of crude oil, it tends to stick on the walls of oil wells and pipelines. Reducing agents are thus used to reduce the sticking of crude on the walls so that the production amount can be increased.

Therefore, the reducing agents in oilfield applications are used to increase the production and recover most of the crude oil. They also work as drag reducing agents to reduce turbulence in a pipeline by making the crude oil non-sticky and allowing oil to flow more smoothly & efficiently.

The following are the four types of drag reducing agents used:

  • Surfactants
  • Biological Additives
  • Polymers
  • Solid particle suspensions
