Description:

Pure-Bore is a dry free flowing polymer that mixed with water produces a natural biodegradable drilling fluid, which can be used in a variety of drilling applications.

Pure-Bore
provides exceptional bore hole stability and cuttings removal in a wide range of ground conditions.

Functions:

• Biodegradable drilling fluid
• Effective in all ground conditions (one sack drilling fluid)
• High viscosity for efficient hole cleaning
• High Yield Point and Gel Strength for maximum cuttings suspension and transport
• Provides exceptional bore hole stability in unconsolidated formations
• Provides clay and shale inhibition
• Minimises formation damage
• Maximises production rates
• Can be cleaned down through regular de-sanders

Benefits:

• NON-TOXIC
• Fast and efficient mixing in fresh and salt water
• Stable whilst drilling
• Recycles
• 3 Kilos of Pure-Bore provides the same viscosity as 60 Kilos of civil engineering
• grade bentonite or 25 Kilos of high yield bentonite
• Naturally biodegrades (stabiliser can be added to retard biodegradation)
• Can be chemically destroyed with calcium hypochlorite
• Low cost slurry disposal. Destroy or Biodegrade the Pure-Bore™ polymer to settle out
• drilled cuttings in a settlement pit. The fluid phase can then be treated at a sewage
• treatment works leaving semi dry cuttings

Preparazione

Add slowly and uniformly through a high-shear venturi type hopper. Continue
to agitate/circulate until Pure-Bore is fully dispersed
