CETCO has announced NSF/ANSI/CAN Standard 60 certification for the company’s Rel-PAC Xtra-Low filtration control additive. In a release, the company says the low-viscosity, non-fermenting dry polymer is designed for use as a filtration control additive for a variety of drilling fluid applications.
Rel-PAC Xtra-Low, the company says, works in bentonite or polymer-based fluids to increase borehole stability by lowering filtrate and fluid loss more effectively than other PACs. Rel-PAC Xtra-Low aids cleaning by not significantly raising viscosities and impeding flow. It also helps control reactive formations by reducing available water and controls unconsolidated formations by reducing fluid loss.
