Packer Element For CCUS/CO2 wells
CNPC USA has developed a series of packer element compounds specifically for CCUS and CO2 wells. The elastomer packer elements have been manufactured at commercial scale by CNPC USA quality-controlled compounding and molding processes.

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 ℃)
