Defoamers/Antifoamers

Earth Pro Defoamer Powder is a cement slurry defoamer recommended to decrease foaming and minimize air entrainment in cement slurries while mixing. Oilfield Cementing: Typical dosage in field applications is 2.0-5.0 kg/ton of cement, depending on the expected severity of the foaming problem and slurry viscosity (certain cement additives generate stable, almost untreatable foam if an anti-foaming additive is not […]

Oilfield Cementing: Typical dosage in field applications is 0.5-2 L/m³ of cement slurry, depending on the severity of the foaming problem and slurry viscosity. Optimally, this product should be applied at a constant rate throughout the cement job, but slug applications for quick foam suppression can be applied in extreme circumstances. Operator experience is extremely important when using this […]
