Welltec’s new Well Tractor NG got off to an amazing start when it tractored an impressive 423,724 ft (80 miles) in a highly deviated well offshore Norway.
This achievement took place during a major intervention campaign in the Statoil operated field, Oseberg B, in the North Sea. The operator planned to re-perforate a series of existing intervals as well as add new zones. Oseberg B is notorious for its limited rig up height of only 41 ft, adding complexity and reducing tool lengths for all operations.
Following a successful e-line, scale milling operation performed with the Well Miller, the Well Tractor NG conveyed third party perforating guns for 17 descents. 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 (80 miles) in one trip to the wellsite. Also impressive for the operation was the average tractoring speed of 3,720 ft/hr.
The previous record for total distance tractored in a single well was 282,110 ft (53 miles), which the 318 Well Tractor NG exceeded by 141,614 ft (26.8 miles); a full 50% further.
