The “XO/XD” Circulating Sleeve provides a convenient way to establish or shut off communication between the tubing and the annulus. Any number of these sleeves may be run in a tubing string, and any or all of them may be opened or closed in one run by standard wireline methods.

Design Features:

  • Features a nipple profile above and a packing bore above and below the communication ports.

  • Ports can be closed without leaving any obstructions in the tubing once the shifting operation is completed.

  • The Model “B” Shifting Tool is used to open (jarring down) or close (jarring up) the “XO/XD” Circulating sleeve.
