Conveyance Well Tractor® NG completes 80 miles on one job

The final objective was to re-perforate existing zones and to add new ones. Oseberg B is notorious for its limited rig up height of only 41 ft, adding complexity to all operations.
For many intervention solutions this reduced tool length requirement would be a show stopper but not for the short Well Tractor Next Generation (NG).
Over the course of the operation, the Well Tractor NG performed a total of 21 flawless runs, setting a new world record by tractoring a total distance of 423,723 ft (129,150 m) in one trip to the well site.
Also impressive for this operation was the average tractoring speed of 3,720 ft/hr (1,134 m/hr).
Performing the entire intervention campaign on e-line proved to be both safer and more efficient as very long distances were tractored quickly and with no misruns.
The Well Tractor was regarded as a revolution in the industry when it was introduced in the 1990’s. It enables operators to extend the reach of traditional e-line deployment into highly deviated and horizontal wells.
Welltec Release Device (WRD®) is a simple tool which adds versatility and risk reduction to the operation. It provides predetermined locations in the toolstring where it can be parted, should it become stuck.
