Description
Technical Parameters
Shale stabilizer/filtration control additive is sulfonated asphalt, partially soluble in water and oil, and can be used in water and oil-based fluids where its function as a shale stabilizer, cuttings dispersion inhibitor and contributes to high temperature fluid loss control. It is stable to many drilling fluid contaminants, operates at a broad pH range and is suitable for use up to 500°F.
Applications/Functions
- Reduces HPHT fluid loss in both water-based and oil-based mud
- Stabilizes shales and prevents sloughing
Advantages
- Thermally stable up to 500°F
- Controlled water and oil solubility to achieve optimal chemical and physical performance
- Reacts with shales to prevent sloughing and swelling
- Significantly increases lubricity
- Readily disperses in water and oil fluids
- Extremely temperature stable – does not have the softening point typically associated with naturally occurring asphalt
- Minimal and easily distinguishable fluorescence
Typical Properties
- Appearance: Black powder
- Specific Gravity: 0.98
Recommended Treatment
- Typical range: 2-6 ppb
