ECOTROL F filtration-control additive can be used in all oil- or synthetic-based mud systems.

This product readily disperses into a fluid system through standard mixing equipment, thus minimizing the potential for polymer ‘fish-eyes.’

Complementing the emulsifiers of oil- and synthetic-based mud systems, ECOTROL F additives provide tight HPHT fluid-loss control at low concentrations. It has excellent dispersion and solubility in paraffins even at low temperatures and does not plug downhole screens. ECOTROL F filtration-control additive is effective in 100%-oil applications at temperatures up to 191 degC [375 degF].

Typical Physical Properties  
Physical appearance Free-flowing white powder
Odor Odorless
Specific gravity 1.03
Solubility in water Nonsoluble
Solubility in oil-based fluids Swells in most base oils

Applications

Add ECOTROL F additive at concentrations between 2.9–11.4 kg/m3 [1 to 4 lbm/bbl] depending on fluid-loss-control requirements.

Based on unique technology, ECOTROL F filtration-control additive has been modified to provide superior high shear stability without polymer degradation.

ECOTROL F filtration-control additive contributes to the rheology of the fluid by keeping the low-shear viscosity elevated and maintaining some suspension capability of the mud in HPHT conditions.

Finally, ECOTROL F filtration-control additive enhances the required synergy between organophilic clays and traditional filtration-control additives in order to obtain optimal HPHT fluid-loss performance.

Advantages

  • Reduced HPHT fluid loss at temperatures up to 191 degC [375 degF]
  • Supplemental additive for rheology enhancement
  • Easily mixes through the mixing hopper with less tendency to agglomerate (fish-eyes)
  • Good dispersion and solubility in paraffins even at low-temperatures and does not plug downhole screens

Limitations

  • Overtreatment can cause increased viscosity in a high-density fluid
  • Pilot testing is suggested prior to adding to the active system

Toxicity and handling

Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.

Packaging and storage

ECOTROL F filtration-control additive is packaged in 25 kg [55.1 lbm] multiwall paper sacks. Store in dry, well-ventilated area. Keep container closed. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.
