Well Stroker®

For actuation

Introduction

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.
