The PARVEEN Model D-2 shifting tool is used to provide a safe, selective and controlled method of opening and closing Model ‘L’ sliding sleeve.
Advantages:
- Automatic locating collet: Flags the operator when a sleeve is reached. It also indicates when the tool passes through a sleeve or a nipple.
- Proof of completed shift: As soon as a shift, either open or close, is co m pleted, an attempt to repeat the operation will give a positive indication that the shift was performed.
- Safety feature: If the sleeve is opened in the presence of a differential pressure in favour of the annulus, the release mechanism is held inoperative by the flow until the pressure is balanced to allow safe removal.
- Open and close sleeves in one trip: Shifting tools can be run in tandem if required to both open and close sleeves on the same run in a well. Run the tool with collect up to open sleeves or with collect down (Inverted position) to close sleeves.
- Deliberate release: Even after the shifting tool is seated in the sleeve, it can be released without shifting the closing sleeve.
