Tubing and casing Leak Detection in water injection well case study by SNL and HPT

Leak detection case study is made based on offshore water injection well job performed by North Side company. Client suspected tubing leak and requested to deploy Spectral Noise Tool (SNL) along with HPT to locate tubing leak.
Job was done by two runs. The first run was done in shut in condition where casing leak was located based on SNL and HPT responses. The second run was done while injection of the sea water into the A-annulus of the well, so explicit tubing leak was located above casing leak. Casing leak was also confirmed during injection run of the SNL & HPT tools.
