SiberProp™ Proppants


SiberProp Product Photo

SiberProp™ proppants are a Stress Bond™ technology resin coated sand available in a 16/30 mesh size. Tan in color, the SiberProp resin system is applied to high quality frac sand. The unique properties of the SiberProp resin have redefined curable proppants. By using a specially formulated resin system, SiberProp proppants develop significant strength in the bonded pack at very low bottom-hole temperatures without the need for external consolidation aids.

Typical Applications

Fracture treatments:

  • At closure stess up to 8,000 psi [55 MPa]
  • At bottom-hole static temperatures from 130 - 200°F [54 - 93°C]
  • When high strength in the bonded pack is necessary or desirable at very low temperatures


Technical Advantages and Benefits

  • Low temperature bonding down to 130°F [54°C] bottom-hole static temperature without the use of a low temperature consolidation aid
  • Optimized AcTivator™ consolidation aid loading recommendations are available based on well specifics to maximize performance and minimize additional cost to the operator
  • Higher strength in bonded pack at lower temperatures than conventional curable resin coated proppants
  • Consolidates with closure stress in the fracture
  • Helps prevent proppant flowback
