Confidence and safety with NOV casing running tools

Our aim is to increase crew safety and improve rig operations with hands-free and fully automated casing handling operations. We are bringing innovations to the drill floor with providing integrating casing tongs, handling equipment, torque verification, and zone management. 

Casing Module CM-22 and Torque Turn

The casing module consists of an upper tong, backup tong, and a stabbing guide. It is easily and quickly hooked on to the roughneck by hydraulic and electric quick connectors. Zone management and safety systems, including the NOV Torque Turn casing drilling logging system, ensure efficient, safe, and reliable makeup and breakout performances when fully automated and integrated into NOV control systems. The Torque Turn logging system is designed to monitor and log data from casing pipe spin-in and makeup operations and to perform data analysis according to given criteria for an acceptable connection. Torque Turn integrated casing tongs and NOV’s casing-ready pipe rackers enable the rig crew to perform all casing pipe handling and logging under the supervision of professional casing supervisors.

Together with a third-party approved torque verification sub, this setup ensures casing tong performance, including documentation and logging of a safe and reliable casing connection. Torque Turn visualizes the torque curves and suggests the torque shoulder point for makeup and spin-in operations. The system’s analysis function assists the operator by identifying and assessing the casing connection execution. The operator is prompted to revise the connection analysis before acceptance or rejection, introducing a systematic method to ensure a consistent approach for maintaining integrity of the entire well.
