Black Ultra™ Proppants


Black Ultra

Black Ultra™ proppant, available in 16/30, 20/40, and 30/50 mesh sizes, is a next-generation resin coated proppant utilizing a multi-functional resin system, which bonds at low temperatures without the use of a consolidation aid. In addition, the resin alters the relative permeability of the proppant pack, leading to optimized oil production. It also contains re-healing properties, important for cyclic stress that occurs over the life of the well. In addition to these features, the Black Ultra proppant Stress Bond™ technology delivers all the benefits of a curable resin coated proppant, such as flowback control and enhanced well production.

Typical Applications

Fracture treatments:   

  • At closure stress up to 8,000 psi [55 MPa] (16/30 and 20/40) and 10,000 psi [69 MPa] (30/50) 
  • At bottom-hole static temperatures from 90 - 160°F [32 - 71°C]
  • Where flowback control is necessary in low temperature reservoirs


Technical Advantages and Benefits

  • Low temperature bonding down to 90°F [32°C] bottom-hole static temperature without the use of a low temperature consolidation aid
  • Resin re-healing characteristics 
  • Minimizes proppant embedment
  • Reduces proppant fines generation and migration
  • Helps prevent proppant flowback
  • Stress Bond technology helps prevent wellbore consolidation
  • Frac fluid and beaker friendly
