Defoamer W-1 is a highly water dispersible silicone formulation designed for general purpose defoaming. It will prevent foam in degassers, coil tubing units, pits, return tanks and other equipment where there are foam problems. The defoaming ability of Defoamer W-1 may improve the quality and quantity of production by eliminating foam and foam carry-over and improving the efficiency of treating equipment.
Typical Physical Properties
| Appearance |

Applications
Because each application varies, it is suggested that 0.05 – 0.1 ppm be used initially, with a gradual lowering of the treating rate as determined by operating conditions. Severe foaming may need to be treated with 0.2 ppm.
Advantages
The low ppm range in where Defoamer W-1 is effective makes it an economical choice. Defoamer W-1 is safe to use in degassers, coil tubing units, production vessels, pits, return tanks and other equipment where fluid foaming may be a problem. Defoamer W-1 is highly dispersible in WBM systems containing fresh or seawater and is highly effective in the control of foam in viscous brines and spacers. Defoamer W-1 is ideal for treating foam generated by air drilling/air misting operations in where a surfactant or soap is purposely pumped downhole for cuttings lift.
Environmental Data & Handling
Although Defoamer W-1 is a low toxicity product, Bio-assay informatioin is available on request. When used as directed and tested according to the U.S. Environmental Protection Agency’s Static Sheen Test, Defoamer W-1 does not create sheen on the surface of receiving waters.
