Subsea safety valves (SSSV) are safety-critical when a well hassufficient reservoir pressure to flow naturally. Among other things, they areused to secure offshore wells during hurricanes to prevent pollution in theunlikely event the wellhead sustains damage. They are tested regularly and mustbe reliable.

While testing a SSSV in one of its wells in the Campeche Bay, amajor Latin American Operator discovered scale deposits that prevented the SSSVfrom sealing shut. The operator was looking for an alternative mechanicalsolution, since pumping acid into its wells had not been effective. A downholetractor service provider approached the operator and after carefully studyingthe case, presented the wishbone honer brush design run on a well tractor andelectric line to repair the valve in situ and avoid costs associated withmobilizing a rig and removing well components. It was the first time thistechnology was used successfully for this application.
