Houston, TX
Halliburton (NYSE: HAL) announced the successful deployment of its VersaFlex® expandable liner hanger system in the bp-operated Azeri–Chirag–Gunashli (ACG) project offshore Azerbaijan in the Caspian Sea.
The deployment was completed at West Azeri C44, one of bp’s key wells for the year, and marks the first installation of the new 13⅜ × 16 in. VersaFlex expandable liner hanger system in the field. The system replaced a conventional liner hanger that had been used for more than a decade and delivered improved performance across multiple liner sizes.
The VersaFlex expandable liner hanger system’s bidirectional design supported bp’s well integrity and well construction objectives. According to Halliburton, the deployment helped reduce well construction time by approximately two days while maintaining consistent execution quality in a demanding offshore environment.
“Our teams delivered consistent, dependable performance in a demanding offshore environment, demonstrating the strength of close collaboration on the project,” said Maxime Coffin, vice president of Halliburton Completion Tools.
The qualification process began in late 2022 after bp requested technical confirmation of Halliburton’s ability to deliver the VersaFlex expandable liner hanger system for ACG field requirements. Over the following two years, Halliburton worked with bp’s local, regional and central teams through technical reviews, discussions and internal evaluations to validate the system for the project.
To support anchoring and sealing performance, Halliburton recommended a finite element analysis approach tailored to ACG’s operating conditions. The method reduced the need for extended revalidation and provided a technical basis for system performance.
The successful deployment reinforces Halliburton’s role as a trusted technology provider for complex well construction projects in the Caspian region. It also highlights the company’s focus on delivering completion solutions that support customer objectives throughout the well life cycle.
