CARBOBOND KRYPTOSPHERE XT resin-coated high-density, ultra high-performance ceramic proppant

CARBOBOND® KRYPTOSPHERE® XT resin-coated, ultra high-performance ceramic proppant is effective at greater well depths, temperatures and stresses than any comparable ceramic proppant. CARBOBOND KRYPTOSPHERE XT also requires 20% less proppant by weight than any resin-coated intermediate-density ceramic proppant and 30% less proppant than any resin-coated bauxite ceramic proppant. It is designed with high cyclic loading tolerance, and the bonded proppant pack reduces the effective stresses encountered at deeper depths. 



  • CARBOBOND KRYPTOSPHERE HD provides an ultra-conductive proppant as the substrate
  • Specially formulated for maximum compatibility with complicated frac fluids used in deeper wells 
  • Bonded proppant pack reduces effective stress on proppant 
  • High cyclic loading tolerance
  • Resin coating completely encapsulates substrate
  • Bonds in the fracture with temperature and closure 


  • Versatile—expands the usable application range (depth, temperature and stress) to replace intermediate-density and bauxite
  • No proppant flowback—eliminates subsequent equipment damage, expense of cleanouts and disposal
  • Maintains conductivity—resin coating prevents fines from being released
  • Maintains particle integrity—prevents chemical attack on substrate
  • No additional chemical costs—since no fluid chemistry change is required, the job can be pumped as designed
