The hydraulic control line from a sub-surface safety valve (SSV) failed in service approximately 9 months after well completion. An insert SSV was placed in the well and the spare hydraulic control line also failed following approximately 9 months of service. The well was worked over to replace the failed control lines. A study was performed to determine the failure cause and recommend measures to prevent future reoccurrence. Analysis revealed the UNS N08825 control line failed due to halogen ion stress corrosion cracking. The primary source of halogen ions was due to high temperature decomposition of the fluoropolymer encapsulation. Bare, non-encapsulated UNS N08825 control lines will be installed in future area completions until an encapsulation material suitable for the unique environment is identified.
