AquaBond™ Proppants


New AquaBond

AquaBond™ proppants are one of our latest innovative technology platforms available in 20/40, 30/50, and 40/70 mesh sizes. These advanced proppants utilize a unique resin chemistry that reduces the production of formation water by altering the relative permeability of water through the proppant pack.  This increases the profitability of the well by reducing waste water storage and disposal costs.

Typical Applications

Fracture treatments:    

  • At closure stress up to 10,000 psi [69 MPa] 
  • At bottom-hole static temperatures from 120 - 450°F [49 - 232°C]
  • Vertical and horizontal wells
  • Refracs
  • Any well where water production is an issue

Technical Advantages and Benefits

  • Reduces the production of formation water while maintaining oil and gas production
  • Minimizes proppant flowback
  • Reduces proppant fines generation and migration
  • Minimizes proppant embedment
  • Stress Bond™ technology helps prevent wellbore consolidation
  • Frac fluid and beaker friendly
