Earth Pro Red Dye is a synthetic iron oxide pigment used to color cement or water based fluids.
Oilfield Cementing Colorant:
Earth Pro Red Dye is a water dispersible pigment, which can be used as an indicator for determining the pre-flush/cement interface when cementing oilfield casing.
Typical application rates range from 1-2 water soluble bags per cubic meter of pre-flush. Since the product is almost inert, there is little or no effect on cement integrity at the fluid interface. In critical holes, pre job tests should be conducted to confirm original cement characteristics.
Indicator Dye for Liquids:
Earth Pro Red Dye can also be used to color displacement fluids to identify returns when displacing drilling muds. The addition of one water-soluble bag per cubic meter of water is sufficient to provide a brilliant sustainable color that is easily recognizable even when moderately contaminated with well bore materials.
