During oil and gas production, foam bubbles can form, and their presence is detrimental to the quality of the products. Typically, foams are caused when gas is introduced and settled into a solution. The depressurization of hydrocarbons in oil and gas production forms gas entrainment, which leads to negative impacts on production, including safety hazards, liquid carryover, reduced separation, false reading, and an overall inefficient system.

The formation of foam bubbles must be reduced or eliminated to ensure product quality, improved productivity, and reduced production cost. One of the many methods to manage foam is by chemical control using antifoam agents or defoamers, which counteract foam formation.

Crucible Chemicaloffers defoaming solutions that improve the efficiency of oil and gas production systems. Our products include silicone, organo-silicone, non-silicone and powder defoamers, which are suitable for oil and gas and many other applications.

How Is Foam Formed in Oil and Gas Systems?

Foams from crude oil are called ‘foamy oil’ that form during the actual extraction of oil from the well or in the tank used to separate oil from water and gas. These foams result from the depressurization of dissolved gas into the oil. Foams damage downstream compressors and can lead to tank and equipment spills.

Benefits of Using Defoamers During Oil and Gas Production

Defoamers and antifoaming agents are widely used in oil and gas production to control, prevent, and remove foams in a solution. While defoamer and antifoaming agents are used interchangeably, they offer distinct features to their users. Defoamers are foam control agents used to reduce or eradicate foams. Meanwhile, antifoaming agents are employed in a system to prevent the emergence of foams.

Increased Unit Capacity

Foaming lowers the capacity of deaerators, gas scrubbers, effluent systems, glycol regenerators, two- or three-phase separators for crude oil production, and gas compressors. Defoamers are ideal for revamping these units to maximize their performance.

Increased Cost-Efficiency

Foam control agents like defoamers help decrease the probability of operational interruptions caused by foaming in gas compressors and glycol regenerators.

Decreased Cost Production

Defoamers control the contamination of separated gases or liquids in two- or three-phase separators for crude oil production, gas scrubbers, and gas compressors. As a result, oil and gas production costs also decrease.


Defoamers help reduce the risks of fire, spillage, and pollution.

Increased Lifetime of Process Equipment

The persistent presence of foam strains process equipment, forcing it to wear and drastically shrinking its lifespan. Using defoamers will help manufacturers maintain their equipment and preserve its longevity.

Applications of Defoamers in the Oil and Gas Industry

Defoamers keep foaming in check and prevent unfavorable effects on oil and gas production. They are utilized for several applications in the oil and gas industry, including:

  • Gas oil separators
  • Glycol dehydrators
  • Gas sweetening
  • Delayed cokers
  • Propane deasphalting
  • High-detergent motor oils
  • Amine scrubbing units and cooling
