3M™ Glass Bubbles for Low Density Drilling Fluids


Of the two methods for lowering drilling fluid density - aeration or the addition of microspheres - only the addition of 3M™ Glass Bubbles ensures that the drilling fluid will be incompressible. This ensures the ability to maintain a constant pressure down-hole. In addition, 3M glass bubbles ensure:

  • Simple hydraulic calculations
  • Smooth measurement while drilling (MWD) transmission
  • No need for expensive compressors
  • Less likelihood of corrosion to the drill string
  • Reduced explosion potential
