High-temperature filtration control agent
ONE-TROL HT filtration control agent is designed for use in all oil- and synthetic-based drilling fluid systems. The product may be used in combination with other filtration-control additives or as an effective alternative to asphalt and gilsonite where their use is undesirable. ONE-TROL HT agent is compatible with other oil-based or synthetic-based additives.

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.
Effectiveness is reduced at temperatures approaching 400 degF [204 degC], requiring higher concentrations.
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.
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.
