Foam-related issues are a persistent challenge across the oil and gas industry, from upstream drilling and production to midstream processing and wastewater treatment. Foam can disrupt separation efficiency, reduce throughput, increase chemical consumption, and even trigger safety risks during high-pressure operations. As production conditions become more complex, the role of a well-matched defoamer becomes increasingly important for stable and efficient operations.

Key Defoamer Application Scenarios in the Oil & Gas Industry
Different processes generate foam for different reasons, and defoamer selection must align with actual operating conditions rather than relying on a one-size-fits-all solution.
Application Area
Foam Source
Recommended Defoamer Type
Crude oil separation
Natural surfactants, gas entrainment
Silicone-based defoamer
Drilling fluids
Polymers, surfactants, high shear
Polyether-based defoamer
Produced water treatment
Oil residues, chemical additives
Compound defoamer
Refinery wastewater
Detergents, emulsified oil
Silicone or hybrid defoamer
In produced water treatment systems, for example, adding 0.03–0.08% of a properly selected defoamer can significantly reduce surface foam during continuous operation, helping maintain separator efficiency without affecting downstream treatment performance.
Silicone vs. Polyether Defoamers: Which Works Better in Oil & Gas?
Understanding the differences between defoamer chemistries helps operators make more reliable choices under demanding conditions.
-
Strong and fast foam knockdown
-
High resistance to temperature and salinity
-
Suitable for crude oil processing and high-load wastewater systems
-
Better dispersion in aqueous systems
-
Lower risk of oil-water separation interference
-
Commonly used in drilling fluids and circulation systems
In high-temperature separators or gas-liquid separation units, silicone defoamers often deliver more consistent results. In contrast, polyether defoamers are preferred where compatibility with fluid systems and controlled foam suppression are critical.
Real Applications, Real Shipments: Rickman in Action
Rickman defoamers are currently supplied to oilfield service companies and wastewater operators across Asia, the Middle East, and Africa. In one recent application, a compound defoamer was delivered for a produced water treatment facility handling high oil content and fluctuating flow rates. On-site feedback confirmed stable foam control over multiple operating cycles, with no negative impact on oil-water separation efficiency.
Each shipment is prepared according to customer specifications, including packaging type, labeling, and logistics requirements. From bulk IBC containers to customized drums, Rickman ensures products arrive ready for immediate use under field conditions.
Why Oil & Gas Clients Choose Rickman Defoamer
Beyond product performance, Rickman places strong emphasis on service and long-term cooperation. Our technical team works closely with customers to evaluate system parameters such as temperature, salinity, shear force, and chemical compatibility before recommending a solution. Sample testing, formulation adjustment, and post-delivery support are all part of Rickman’s service approach, helping customers reduce trial-and-error costs and improve operational reliability.
FAQ
Q1: How do I select the right defoamer for oil and gas applications?
A: Selection should be based on process conditions such as temperature, salinity, shear force, and foam persistence. Field testing and technical evaluation are strongly recommended before large-scale use.
Q2: Are silicone defoamers always better for oil and gas systems?
A: Not necessarily. While silicone defoamers offer strong knockdown performance, polyether or compound defoamers may be more suitable for certain drilling fluids or wastewater systems where compatibility is critical.
Q3: Can Rickman provide customized defoamer solutions for oilfields?
A: Yes. Rickmanoffers application-specific formulation adjustments and technical support to match different oilfield conditions and operational requirements.
