Introduction
———

DYOL-H3 is an amine-treated organic lignite designed for oil-based mud (OBM) / invert-emulsion systems.
It is used to improve HTHP filtration control and support emulsion stability, helping promote a stronger reverse-emulsion structure—especially in deep / high-temperature intervals.
DYOL-H3 is water-insoluble and formulated for thermal performance up to 180°C (356°F), with low toxicity for routine field handling (follow local HSE practices).

Applications / Functions
—————

• Supports HTHP fluid-loss control in OBM / invert emulsions

• Helps strengthen and stabilize the reverse-emulsion system (supports ES stability)

• Contributes to improved rheology control and stable mud performance in high-temperature sections

• Water-insoluble, suitable for oil-continuous systems

Advantages
———

• Designed for invert-emulsion stability and consistent performance at elevated temperature

• Helps reduce filtration tendency and supports a more stable wellbore environment

• Low toxicity and environmentally considerate option (as per typical organic lignite use)

Recommended Treatment
—————

Typical dosage:

• Dosage is system-dependent. Optimize by lab testing based on target HTHP FL, ES, and rheology.
