Invert-emulsion wetting agent
Reverse a water-wet solids problem and return the surface area of the solids to an oil-wet environment.
Hematite weighting agent
FER-OX weighting agent is a high-quality, ground iron oxide with a specific gravity of 5.0 or above. Because of its high specific gravity, muds formulated with FER-OX weighting agent have lower solids content and frequently contribute to higher rates of penetration compared with barite muds.
It can be substituted for or blended with barite in all mud systems. FER-OX weighting agent is ground and processed to remove impurities, then classified to achieve the desired particle size distribution.
|Typical Physical Properties|
|Physical appearance||Dry: Red to brown powder|
|Wet: Gray to black|
|Muds: Deep reddish brown|
|Bulk density||2,178 kg/m3 [136 lbm/ft3]|
|Particle hardness||5–6 Mohs hardness scale|
FER-OX weighting agent is applicable in all types of drilling fluids, including freshwater, seawater and oil-base muds. It can be used to increase the density of all drilling and completion fluids to 25 lbm/galUS [3.0 s.g.]. FER-OX weighting agent is most frequently used in high-density, oil-base muds.
Fluids weighted with FER-OX weighting agent contain fewer solids by volume than those weighted with barite, making higher mud weights possible. It is especially useful in high-density kill fluids.
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.
FER-OX weighting agent is packaged in 45.4 kg [100 lbm], multiwall, paper sacks and is available in bulk. Store in a dry, well-ventilated area. Keep container closed. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.
