ONE-TROL HT

High-temperature filtration control agent

Typical Physical Properties
Specific gravity	1.3
Physical appearance	Dark brown powder
Odor	Tannin
Solubility in water	Slightly
pH	4.75 (5% slurry)

Applications

ONE-TROL HT agent can be used in any oil- or synthetic-based drilling fluid system to control fluid loss. For most applications, recommended concentrations are 4 to 10 lb,/bbl [11.4 to 28.5 kg/m3] of ONE-TROL HT agent. The concentration may need to be increased for special applications where high temperatures (>350 degF [>176 degC]) are anticipated or where ultralow fluid loss is required. Pilot testing is recommended to determine the required ONE-TROL HT agent treatment level and the effect on properties. ONE-TROL HT fluid-loss control agent is stable to temperatures in excess of 500 degF [260 degC] with minimal effect on the rheological properties of the mud.

Advantages

Effective filtration control alternative to asphalt, gilsonite, and amine treated lignite products
Applicable to all oil-based and synthetic-based systems
Compatible with other additives
Disperses easily when added through a hopper

Limitations

Effectiveness is reduced at temperatures approaching 400 degF [204 degC], requiring higher concentrations.

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

ONE-TROL HT agent is packaged in 50-lbm [22.7-kg] multiwall paper sacks. Store in a dry, well-ventilated area. Keep container closed. Keep away from heat, sparks, and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.
