Foaming Agent

Definition - What does Foaming Agent mean?

A Foaming Agent is a chemical that facilitates the formation of foam when added to fluids. Foaming agents reduce the surface tension of a liquid so that it can easily form bubbles. During oil well drilling, a foaming agent is used to facilitate foam formation in water so as to use it as a drilling fluid. Drilling fluid foaming agents should be able to withstand high temperature, high salinity, entrained oil, hard water and other solids which are usually present during drilling operations.

Petropedia explains Foaming Agent

Foaming agents are added to fluids so as to aid in the formation of foam of air or gas bubbles. The foam used in oil wells or natural gas wells is similar to shaving foam but it is able to withstand high temperature, high salinity, entrained oil, hard water and other solids. When water builds up in a wellbore and prevents natural gas from flowing during the natural gas production from gas wells, a foaming agent is added to facilitate foaming of water in gas wells which allows the natural gas to flow. Forming agents are used for several purposes such as shock absorption and heat insulation. A good forming agent should have a superior storage stability, and easy handling.
