Technical Data Sheet

 True North L


True North™ L

Canadian Ultra-Low Temperature Resin Coated Sand with Stress Bond™ Technology



True North™ L proppants are an Innovative curable resin coated sand available in a 20/40 mesh size. The True North L resin system is specifically designed for low temperature reservoirs and is applied to Canadian (domestic) frac sand. Incorporating Hexion's latest Stress Bond™ technology, the proppant bonds in the fracture with closure stress, providing increased fracture flow capacity and proppant flowback control. Additionally, the resin system reduces dust generation during the pneumatic transfer* and conveying process, which helps improve health and safety on location.



Fracture treatments:     

  • At closure stress up to 55 MPa [8,000 psi]
  • At bottom-hole static temperatures from 21-71°C [70-160°F]
  • Where flowback control is necessary in low temperature reservoirs


  • Low temperature bonding down to 21°C [70°F] bottom-hole static temperature without the use of a low temperature consolidation aid
  • Reduces proppant fines and migration
  • Reduces dust generation*
  • Helps prevent proppant flowback and rearrangement
  • Stress Bond technology helps prevent wellbore consolidation
  • Frac fluid and breaker friendly


  • Grain-to-grain contact must occur and closure stress must be applied during the cure period for proper bonding
  • Consolidation of curable product at bottom-hole static temperatures below 21°C [70°F] is achieved by use of Hexion's AcTivator™ low temperature consolidation aid
