Model D-2 Shifting Tool

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:

1. Automatic locating collet: Flags the operator when a sleeve is reached. It also indicates when the tool passes through a sleeve or a nipple.
2. 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.
3. 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.
4. 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.
5. Deliberate release: Even after the shifting tool is seated in the sleeve, it can be released without shifting the closing sleeve.
