For actuation
The Well Stroker can push or pull multiple times in the same run irrespective of the depth and deviation. It delivers up to 100,000 lbs of axial force downhole using a bi-directional hydraulic ram.
Interventions can even be performed when the well is still under pressure, which precludes having to ‘kill’ the well.
The Well Stroker provides the flexibility to be incorporated in a wide range of completion designs for cost-effective workovers and other applications where downhole force is required.
Featured case
An offshore client contacted Welltec® about closing well intervals to mitigate a water cut issue. The client was experiencing nearly 70% water cut in a 15,748 ft...
The Well Stroker resides at the core of Welltec’s mechanical solution portfolio. This tool provides the actuating force required for most mechanical intervention jobs.
It can push or pull multiple times in the same run irrespective of depth or deviation, applying up to 100,000 lbs of axial force downhole through the use of a bi-directional, hydraulic ram which can be equipped with the required fitting to meet the application.
