ReLine WL – Expandable Technology

ADVANCED MECHANICAL EXPANSION FOR WELL COMPLETION AND INTERVENTION

In today’s oil and gas environment, where efficiency and cost-effectiveness are paramount, the ReLine WL system from Coretrax and Expro is redefining how operators approach well remediation and completion — all without the need for a rig.

 

RIGLESS WELL INTERVENTION – MAXIMUM EFFICIENCY

ReLine WL is a mechanically expanded patch system deployed via e-line, designed to tackle downhole challenges such as: Water or gas ingress Leaks across connections, liners, or sleeves Corrosion or erosion in tubing Flow profile changes or sand control The mechanical expansion system uses a hydraulic piston and expansion cone to deliver high-strength, high-integrity seals while maintaining maximized internal diameter (ID) post-expansion.

 

KEY FEATURES

✅ Rigless Deployment: Saves time and operational costs

✅ Mechanical Disconnect: Enables safe retrieval and redeployment

✅ Stackable Design: Covers extended intervals with multiple patches

✅ Larger Post-Set ID: Maximizes future well access

✅ No Overpull Required: Minimizes risk to equipment and wireline
