Now the operator considered coiled tubing (CT), which would be able to deliver the required force but would also add complexity and costs to the operation. Interested in returning the well to production as soon as possible the operator approached Welltec® for an e-line solution. Recent developments enabled the mechanical Well Stroker® XXS to provide 60,000 lbs of force, sufficient for the fishing operation.
During the first run, a Well Tractor® was used to convey the Well Stroker®, which applied 55,000 lbs of force, successfully releasing the shear ring of the stuck setting tool. A second run was then performed to retrieve the entire fish (the setting tool and slickline toolstring). Finally, the operation was completed by setting the packer.
By performing the operation on e-line with Welltec’s solution offering the operator saved a minimum of five days rig time. Aditionally, not using the full CT package with all the associated costs, time, heavy lifts and emissions netted the customer cost savings of ~ $2 million.
The power, control and accuracy provided by the Well Stroker® XXS was in fact able to perform the same work as much larger methods, delivering significant HSE benefits, operationoal efficiency and cost savings.
