Applications

  • Designed specifically for packer elements in CCUS storage and CO2-EOR injection Wells.
  • Zone isolation during alternate injection of brine and CO2.

Features & Benefits

  • CNPC-USA specially designed formulations and quality-controlled compounding and molding processes.
  • Superior, reliable, and long-lasting sealing performance.
  • Resistance to rapid gas decompression (RGD) at 720 psi/min.
  • Low temperature sealing performance close to -40℃.
  • 20 + reliable setting and unsetting cycles under150°C and 35Mpa pressure differential.
  • Based the side-by-side testing in comparison with the materials from three major North America element suppliers, CNPC-USA CCUS packer element compound is significantly better in
  • 1) CO2 compatibility (lowest change in weight, volume and hardness)
  • 2) Sealing performance after long-term CO2 immersion and RGD (lowest compression set)
  • 3) Structural integrity after long-term CO2 immersion and RGD (least structural damage)
  • 4) Low temperature sealing limit (glass transition temperature close to -40 ℃)
