Mitigate the torque
The Welltec Swivel is a sub that mitigates the torque from the wireline cable to be transferred to the downhole intervention tool allowing continuous tractoring.
In addition, it provides live measurement of the tension level of the wireline on the cable head, allowing the operator to manage the risk of over-pull while keeping the wireline in tension during the operation.
With the hydraulically compensated Welltec Swivel, the risk of unintentionally wrapping the wireline cable due to torque build up through the toolstring is minimized.
Continuous tension measurements at the cable head are sent to the surface, providing live data to allow operator to optimize downhole tools like tractoring speed or milling weight on bit. This helps manage over-pull risks and maintain wireline tension. The Swivel fully integrates with Welltec equipment and surface readout, enhancing operational safety.
