kRT™ Proppants

Description

kRT

Hexion’s kRT™ proppants are a curable resin coated sand available in 16/30, 20/40, 30/50, 40/70, and 100 mesh sizes. kRT proppants are an economical resin coated sand that control proppant flowback in reservoirs down to 110˚F and enhance conductivity.

Typical Applications

Fracture treatments:    

At closure stress up to:

  • 8,000 psi [55 MPa] (16/30 and 20/40) 
  • 10,000 psi [69 MPa] (30/50 and 40/70)
  • 12,000 psi [83 MPa] (100)

At bottom-hole static temperatures* from:

  • 140 - 450°F [60 - 232°C] (16/30 and 20/40)
  • 110 - 450°F [43 - 232°C] (30/50, 40/70 and 100)

*Does not require a low temperature consolidation aid down to recommended temperatures.

Technical Advantages and Benefits

  • Enhanced conductivity
  • Proppant flowback control
  • Proppant fines reduction
  • Cyclic stress resistance
  • Minimizes proppant embedment
  • Reduces respirable silica dust exposure below PEL limits
