AUS - GEL XTRA 22.5kg



high yield premium grade wyoming bentonite

AUS-GEL XTRA 22.5kg is a modified premium grade sodium Bentonite formulated to ensure ease of mixing with superior mud making qualities in fresh water. AUS-GEL XTRA is designed for use in mineral exploration, water well and directional drilling operations. AUS-GEL XTRA has been registered with the USA National Sanitation Foundation (NSF) for use in potable water well construction.


AUS-GEL XTRA is recommended as an ‘ultra’ high yielding viscosifier for building a mud system with excellent hole cleaning properties and low filtrate values in fresh to brackish water. The product makes an economical, low solids drilling fluid which has specific application in water wells with permeable sections or poorly consolidated caving formations. AUS-GEL XTRA yields approximately twice the amount of standard API grade Bentonites.


  • Yields rapidly in fresh water to give ultra high viscosity
  • Economical – single product preparation of a low solids drilling mud
  • Economical – cost effective
  • Enhances fluid loss characteristics
  • Assist in bore hole stabilization
  • Helps eliminate loss circulation conditions
  • Environmentally friendly – does not ferment and is nontoxic
  • NSF/ANSI Standard 60 endorsed.
