Customer Challenges
- A non-flowing well in the Middle East was undergoing a workover to install an ESP when a casing leak was discovered across a 60 ft interval of 7" 23# casing. After 12 unsuccessful attempts to squeeze the damaged section, Expro was engaged to develop a more robust and permanent solution
Expro Excellence
- A 136 ft, 5.5” ReLine HYD patch was engineered to isolate the leak while maintaining a 5.620" internal diameter, ensuring sufficient drift for ESP installation as per the workover plan
- The ReLine HYD solution provided a dependable, permanent fix for the casing leak, outperforming traditional squeeze methods. In addition to saving rig time, the approach contributed to reduced fuel consumption and lower emissions, aligning with operational efficiency and sustainabilty goals
Value to Client
- Using hydraulic pressure from the supplied pumps, the patch was successfully expanded in place, restoring full wellbore integrity and allowing the workover to resume. The entire operation was completed within 48 hours, eliminating ongoing non-productive time (NPT) and enabling the customer to proceed with ESP installation and bring the well back online
