The DEFOAM EXTRA high-performance defoamer is a highly effective silicone defoamer for use in reservoir drill-in and completion fluids. The defoamer can be readily added to water-base fluids to prevent or control foaming, particularly when surfactant additives are used. 

The defoamer is compatible with brine systems and reservoir drill-in fluids as well as fluid-loss-control pills. The DEFOAM EXTRA defoamer has minimal impact on fluid rheology and performs in both monovalent and divalent brines. Laboratory testing is recommended to evaluate performance for specific conditions and in high-density brine applications.
