  • Stable to 500°F (260°C)
  • Assists in preventing barite sag by improving low shear rate viscosity


OptiTrol fluid loss agent is particularly useful in OptiDrill or OptiPhase drilling fluid when bottomhole temperatures exceed 350°F (177°C). It is effective at temperatures up to 500°F (260°C) and can withstand high shear conditions without degrading.

Treatment Recommendation

A concentration of 2-5 lb/bbl is recommended for controlling HPHT fluid loss in oil-based systems at bottomhole temperatures exceeding 350°F (177°C). OptiTrol additive is recommended for use in any diesel- or mineral oil-based drilling fluid system. For other synthetic-based fluids, including Newpark’s CyberDrill® system, the CyberTrol™ HPHT fluid loss control additive is recommended. (Refer to the CyberTrol product data bulletin).
