Cut Downtime. Cut Costs. Keep Wells Flowing. Rigless Tubular Patch Solution Accelerates Large-Bore Well Recovery, Saves $16 Million USD

Restore well integrity and stable production while minimizing cost and downtime.
Maintain large‑bore accessibility for future interventions and surveillance and reduce ESP failure risk.

The conventional approach involves replacing the tubing of the problematic wells and installing a specially coated tubing system to reduce or mitigate corrosion process and allow a longer ESP lifetime. This is a costly option, and it results in a long production downtime for planning and scheduling the wells.
Weatherford casing integrity specialists, alongside experts from wireline, Well Services, and Interpretation and Evaluation Services, collaborated with the operator to analyze a more innovative solution. Based on their assessment of the production logging tools and the ProMAC™ 24-arm caliper tool, the team determined a section of the casing needed to be repaired using an SwagePak straddle system to permanently restore casing integrity.
This advanced tubular patch application is a cost-effective, rigless intervention to overcome this challenge and restore production.
This option helped to isolate the leakage zone(s) with large bore accessibility for any future well intervention operations and surveillance acquiring.

Approximately 3,800 bpd average oil production restored across nine wells. This action also saved 200,000 bbl by eliminating extended downtime while waiting for the workover.
When compared to tubing replacement and by installing only 300 ft (91.4 m) of the tubing path, the Weatherford solution saved $16 million USD due to shorter operations and reduced materials.
The rigless execution minimized scheduling delays and preserved large‑bore accessibility for future work.
This success catalyzed expansion of the technology across the field and other operator assets.
