PXA/PXO Sliding Sleeve
Description
The PXA/PXO Sliding Sleeve is a downhole device normally screwed on the production tubing that allows communication between the tubing and casing. It is used to selectively produce zones in multi-zone completions, stimulate and test zones, displace tubing or casing once the wellhead is installed, kill the well by circulation and allows for the circulation of treatment chemicals or agents. The shifting sleeve has chevron type elastomeric upper and lower seals to ensure maximum seal integrity for extended periods of time downhole. The PXA/PXO Sliding Sleeve’s upper sub has a PX Wireline Profile machined into it. The lower sub has a matching seal bore I.D. The PX Wireline Profile provides a profile to locate and lock into place various flow control devices which may be required from time to time. Pinnacle’s PXA/PXO sliding sleeves are available in a variety of materials, seal and thread combinations.

PXO Operation
The PXO Sliding Sleeve is shifted open using a ‘PB’Shifting Tool. Downward jarring opens the shifting sleeve and upward jarring closes it. The PXO Sliding Sleeve is designed so that normal wireline operations will not open or close it accidentally.
