N Seal
N-SEAL acid soluble lost circulation material is specially formulated, extrusion-spun mineral fiber. Due to its solubility in weak acids, N-SEAL lost circulation material is easily removed from production zones.
- NSF/ANSI Standard 60 certified
- Acid soluble
- Can be easily wetted
- Inorganic and non-fermenting
Application
N-SEAL lost circulation material can be used as an additive for loss of circulation in concentrations up to 70 lb/100 gallons (86 kg/m³).
Typical Properties
Appearance: Grey to white fiber
Specific Gravity: 2.6
Mixing & Handling
N-SEAL lost circulation material can be added directly through the hopper.
- For normal treatment to the active system, add 5-20 lb/100 gallons drilling fluid (6-24 kg/m³)
- As a pill, add 20-70 lb/100 gallons of drilling fluid (24-86 kg/m³)
N-SEAL lost circulation material is 95% acid soluble. To dissolve 1 lb of N-SEAL lost circulation material treat with either:
- 1-2 lb AQUA-CLEAR MGA modified granular acid (1-2 kg/kg) or
- 0.5-1 gal of 10% HCl/5% Acetic acid blend (1-2 liters/kg)
Packaging & Controls
