True North™ Proppants

Description

True North

True North™ proppants are a curable resin coated sand available in 20/40 and 30/50 mesh sizes. This economical product provides all the traditional benefits of curable resin coated sand such as proppant flowback control and proppant fines reduction. Additionally, the resin system reduces dust generation during the pneumatic transfer* and conveying process, which helps improve health and safety on location.

Typical Applications

Fracture treatments:     

  • At closure stress up to 55 MPa [8,000 psi]
  • At bottom-hole static temperatures from 71-191°C [160-375°F]

Technical Advantages and Benefits

  • Helps prevent proppant flowback and rearrangement
  • Reduces proppant fines generation and migration
  • Reduces dust generation*
  • Stress Bond™ technology helps prevent wellbore consolidation
