Offshore East Timor, an inflatable packer had released and migrated up the wellbore, passing through a flapper valve where it then got stuck. To complicate things, a hold-open sleeve dislodged during the migration and landed on top of the valve.

Utilizing a fleet of patented technology including the Well Tractor®, Well Miller® and Well Stroker®, the well was cleared of the inflatable elements and other debris. The series of operations took place in half of the anticipated time and without the need for a workover rig; significantly reducing costs versus budget.
“This was a job well planned and executed. What a great performance by Welltec, which resulted in the well being brought back on-line at 100 MMSCFD flow rate after two years of inactivity. 17 runs were conducted with zero misruns and no HSE or quality incidents, which is an outstanding achievement.” Completions and Well Intervention Coordinator, ConocoPhillips.
