Purpose
The A Slip Stop is used in setting in the tubing strings without upsets. They are typically used at an integral joint where couplings does not exist.
Description
When setting the tapered slip carrier forces the slips tight to the inner tubing wall.
Ran with a shear down pulling tool (SB/JDC). Pulled with a JDC or JUC Pulling Tool.
Application
Set in wellbore to provide a platform to numerous wireline operations, plunger lift, or as a safe guard to prevent debris from falling down the wellbore. May also be used to secure plugging equipment in place.
Operation
Slip type tubing stops are latched into a jar down to the shear pulling tool and attached to the tool string. The stop is lowered down the tubing slowly until desired depth has been reached, the tool string is accelerated downward rapidly. The velocity forces the slips up the tapered slip mandrel setting them against the inner tubing wall.
Downward jarring sets the slips tight to the tubing wall and shears the pulling tool, setting the stop.
Pulling the slip type stop is done by attaching a “JDC” or “JUC” pulling tool to tool string and lowering to the stop depth latching the stop, once the stop is latched upward jarring unseats the stop for removal from the well.
Precautions
Slip type tubing stops require velocity for setting making precise setting depths difficult to achieve.
