 |
ENVIRO-THIN, a chrome-free iron lignosulfonate, controls flow properties and filtration rates of water-based drilling fluids.
The absence of added chrome makes ENVIRO-THIN ideally suitable for use in areas where environmental concerns may limit the presence of chrome in drilling fluid systems.
*Applications/Functions: Reduce flow properties in all kinds of water-based drilling fluids, Provide effective control of filtration rates of water-based muds approaching 350'F(177'C)
*Advantages: Chrome-free, low toxicity thinner for environmentally sensitive areas, Provides effective contaminant tolerance against drilled solids, salt, cement, and anhydrite Is stable at temperatures approaching 350'F(177'C), Effective at low pH ranges (8.0-9.5) |
