Fault Phenomenon: During well control operations, a Cameron 13 5/8″ x 10,000 PSI BOP developed a leak from the side packer, posing a safety risk and requiring immediate action. Reason Analysis: The SBR side packer (046751010002) had degraded due to exposure to high pressure and H2S, causing the rubber to harden and lose its sealing capability. Solution: Replace the worn side packer with a new 046751010002 unit. Clean the BOP cavity to remove debris, lubricate the new packer with compatible grease, and install it following Cameron’s guidelines. Our technical team advised on proper seating to ensure a tight seal. After replacement, the BOP had no leakage, well control operations resumed safely, and downtime was limited to 1.5 hours. Key Takeaway: Regular inspection of BOP packers is critical for well control safety, especially in sour gas environments.

Case 3: VARCO AR3200CM Roughneck Torque Wrench Failure

Fault Phenomenon: A VARCO AR3200CM mechanized roughneck’s torque wrench failed to grip drill pipes properly during makeup, leading to inefficient operation and potential drill pipe damage. Reason Analysis: The TW100 torque wrench die (81788) had worn teeth, preventing it from securing the drill pipe and applying the required torque. Solution: Replace the worn die with a new 81788 unit. Inspect the torque wrench jaw assembly for alignment, adjust as needed, and install the new die following VARCO’s guidelines. Our team provided tips on die maintenance to extend its service life. After replacement, the torque wrench gripped securely, drill pipe makeup time was reduced by 30%, and operations resumed within 1 hour. Key Takeaway: Regular inspection of torque wrench dies ensures reliable drill pipe handling and reduces operational inefficiencies.
