Model GSS Stinger Seal Assembly is a tubing conveyed latching seal assembly that is used to operate the sleeve-valve in an GWR Cement retainer previously set on wireline line. The GSS should always be run with a GTC Tubing Centralizer to provide for easier entry into the Cement retainer.
Provide positive control when the work string is picked up to close the sleeve-valve.
Re-engages each time the work string is lowered to open sleeve-valve.
Detent mechanism prevents cannula from disengaging from retainer during squeezing or tubing testing.
One size operates several sizes of retainers.
Rotate or Snap-out release.
