Technical Bulletin
Description :
Rxsol Defoam A additive is a liquid defoaming agent formulated with higher esters to control foaming in all water-base drilling fluids containing freshwater, brackish water, seawater, saltwater, and saturated saltwater, as well as completion fluids.
Application :
Rxsol Defoam A additive is a wide-application product that reduces the foaming tendencies of water-base muds. It is compatible with freshwater muds, brackish water muds, seawater muds, saturated salt muds, completion brine systems and all common mud additives.It is additive is easy to mix, works quickly, is effective in low concentrations and is a more persistent defoamer than alternative products. Normal treatments of Rxsol Defoam A additive range from 0.29 to 0.58 kg/m³ (0.10 to 0.20 lb/bbl). The use of Rxsol Defoam-A additive is recommended for foam prevention when making periodic treatments with organic materials such as lignosulfonate, lignite and tannin-base additives. When preparing brines, a pre-treatment with 0.72 kg/m3 (0.25 lb/bbl) defoamer is effective in preventing foaming.
Rxsol Defoam-A additive should be added to the mud pits in a location that allows the product to be incorporated into the entire circulating mud system. This additive should not be diluted, but should be added directly to the drilling fluid system by either a drip method from a 5 gal container or as a shock by broadcasting over the surface of the pit. Dilution significantly reduces the effectiveness of the product.
Rxsol Defoam A is a potent anti-foaming agent that is used to suppress and eliminate air entrapment. It is fully compatible with all water-based drilling fluids as well as brine-based completion and workover fluids. It also assists with the release of gas.
