CNPC USA Achieves Another Milestone with GuardPro™ Packer
Milestone Achieved: CNPC USA GuardPro™ Packer Field Tests Successfully Completed
From September 12 to 22, CNPC USA proudly achieved another significant milestone in the advancement of its GuardPro™ production packer technology. The GuardPro™ 5-1/2" V0-grade 200℃/105MPa permanent production packer successfully completed rigorous field tests at the Bozi #5 and Pishan #107 wells in the Tarim Oilfield.
In a single run, the packer was deployed, set, and tested, demonstrating excellent sealing performance under operational pressures up to 119MPa during acid fracturing operations. This outstanding result earned strong recognition from Tarim Oilfield and further validated the reliability of CNPC USA’s engineering capabilities.
This achievement follows the successful field tests of the 7-5/8" and 7" HPHT retrievable production packers, once again proving CNPC USA’s ability to make breakthroughs in high-temperature, high-pressure downhole technology. To date, our team has successfully developed a complete series of packers—including the 5-1/2" permanent, 7" retrievable, 7-5/8" retrievable, and 7-3/4" permanent models—all of which have passed API-11D1-V0 certification.
The success of these field applications not only strengthens the commercialization pathway for CNPC USA products but also underscores the company’s vision for a brighter future in global energy service. This accomplishment is the result of dedicated teamwork, innovation, and collaboration across all engineers and colleagues involved.
Together, we continue to build a solid foundation for CNPC USA’s growth and leadership in advanced well completion technologies.
