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.
