A defoamer or an anti-foaming agent is a chemical additive that reduces foaming formation during industrial processes and operations.

The terms anti-foam agent and defoamer are often used interchangeably. Defoamer chemicals eliminate existing foam, and anti-foaming chemicals prevent the formation of further foam. Defoamers are foam control additives, which are added to a system to reduce or eliminate foam after it has been formed. Antifoaming additives are foam control agents, which are added to a system or formulation to prevent the appearance or emergence of foam. In oilfield drilling and operation, the drilling fluid defoamers and antifoaming additives remove the entrapped air and gas from the water and oil-based drilling fluids.

Defoaming and anti-foaming chemicals are insoluble oils, poly-dimethyl siloxanes and other silicones, certain alcohols, stearates, and glycols. A proper defoaming chemical must have a low surface tension and spread rapidly along the gas-liquid interface, achieving maximum interaction with the foam. As the defoamer spreads in the medium, it must be capable of displacing the foam-stabilizing surface-active components and penetrating the foam’s lamellae to allow the entrapped gas to escape and the foam to burst.

Conventionally, defoamers are formulated around a carrier fluid, possibly a hydrocarbon, silicone oil, vegetable oil, synthetic polymer, etc. Active ingredients, which help spread or destabilize foam, can include waxes, metal salts, silicas, or other hydrophobic particles.

An emulsification system can be incorporated to optimize the spreading and compatibility of the defoamer to a given foaming system.Depending on the chemistry, stabilizing agents such as cellulosic or acrylic thickeners may be added to improve shelf stability. Antifoam agents may also break foams returned from the wellbore during onshore and offshore drilling operations.

At Centum, scientists and engineers have been researching and testing the performance of various commercially available defoaming and anti-foaming additives and chemicals. We formulate the most effective defoaming chemical for onshore and offshore drilling operations upon successful research and development. In every formulation, we prioritize sustainability and performance. This is our core objective. At Centum, we care for drilling operators' and engineers' needs for their projects and operations. Engineers rely on our expertise and experience.

FoamGuard

After years of research and development, we have formulated the most effective and sustainable defoaming additive blend, a sustainable solution for oilfield drillers and operators. In our lab, scientists have studied and tested a wide range of defoamer chemistries, and after careful analysis and testing, we have engineered FoamGuard. Our FoamGuard is effective in a wide range of pH and at high temperatures. We followed guidelines and environmental regulations imposed worldwide and selected the raw materials and additives most effective in varying environmental conditions. Centum’s FoamGuard is proven to offer the ultimate performance during onshore and offshore drilling operations. Without compromising performance, it helps to meet ESG and sustainability targets. Importantly, FoamGuard is non-toxic and does not contaminate seawater, land, and reservoirs. In addition, FoamGuard instantly starts working and meets the driller's performance requirements.
