Application & Dosing

Short intro: Designed for OBM/SBM to cut fluid loss and help seal micro-fractures; stabilizes emulsions and suspension properties under temperature.

• Recommended dosage: 15–30 kg/m³ (optimize by HTHP/filter press)

• When to add: Initial formulation or remedial addition

• Where to add: Active system; compatible with cement spacer use-cases

• WBM use: Treat with surfactants before addition
  Interactive:

• Dose slider (15–30 kg/m³) + mud volume input (m³) → outputs kg required, bags (22.7 kg), and pallets (40 bags).

• Variant picker (190/220/240 °C) that updates the spec row and usage note. 5. NAT-ASF TDS (1)..

Compatibility

• Base fluids: Diesel, mineral oil, synthetic-based; WBM with surfactant treatment

• Operational note: No adverse effect on mud rheology (per sheet claims)

• Role synergy: Filtration control + wellbore strengthening; emulsion stability aid
  

Safety & Handling

• Handle as an industrial chemical; use PPE as per SDS

• Flash point ≥220 °C; avoid heat/sparks/flames

• Bioassay info available on request
  

Packaging & Storage

• Pack: 50-lb (22.7 kg) paper sacks; 40 sacks/pallet
