Innovative Isealate Patch Achieves First-Ever Patch-Thru-Patch Success
A tubing retrievable safety valve (TRSV) at 1,200 ft was obstructing access to a leak in the 3-½” tubing at 6,750 ft. Leveraging the ultra-slim Isealate Springblade Patch, Isealate and Welltec developed a unique solution that allowed for a successful patch-thru-patch deployment without removing previous repairs.
​
Through careful collaboration between Welltec and the client, the intervention was carried out via standard e-line, using the Isealate Patch as a hold-open sleeve in the TRSV, enabling access for additional repairs further downhole. This achievement marks the first-ever patch-thru-patch run, offering a faster, more cost-effective solution for operators.

Successful Remediation of Tubing Connection Leak in Alaska
We are excited to highlight the successful remediation of a tubing connection leak at 5,000 ft using the Isealate Springblade Patch. This intervention on a gas-lift oil producer well in Alaska restored production to optimal levels with minimal impact on the tubing ID.
​Key Achievements:
-
Minimal effect on tubing ID: Only 0.282" (7 mm) reduction
-
Optimized recovery: Production reinstated to peak levels
-
Pressure tested: Held steady at 172 bar with no pressure loss
​
​Through meticulous planning and the deployment of advanced technology, the critical leak was resolved while maintaining well integrity. The pressure test and successful reduction of only 7 mm to the tubing ID ensured smooth production and full client satisfaction.

Effective Leak Remediation with Minimal 4 mm ID Reduction
We are proud to announce the successful first-ever application of the Isealate Springblade Patch, marking a significant milestone in well remediation. This innovative solution was deployed for a European onshore gas producer to address a shallow leak in 3-½” tubing, restoring well integrity with minimal impact on tubing ID.
​
Key Achievements:
-
Minimal effect on tubing ID: Only 4.62 mm reduction
-
Rapid remediation: Full production restored within 24 hours
-
Client satisfaction: 100%
​
In this case, Welltec®’s groundbreaking Isealate Springblade Patch provided a fast and efficient solution, ensuring production could resume in just one day, while maintaining the structural integrity of the tubing with only a minor ID reduction. A successful drift run and pressure test confirmed the effectiveness of the patch, resulting in complete client satisfaction.
