Isolation Jet Sleeve


The T509 Isolation Jet Sleeve allows for a secondary cement job of the casing string above a lost circulation zone without having to drill out cement or plugs. The system can also be run to selectively cement off any zone.
The Isolation Jet Sleeve is run an integral part of the casing string. If lost returns are encountered during the primary cement job, the Isolation Jet Sleeve allows for a secondary cement job. Once the primary cement job is complete, a shifting tool is run into the wellbore to open the Isolation Jet Sleeve and allow for a secondary cement job. Once complete, the excess cement is circulated out of the well eliminating the need to drill out.
Multiple sleeves may be run in a single well allowing for multi-zone cementing. The sleeve uses the Isolation Shifting tool to open and close the Isolation Jet Sleeve. The Isolation Jet Sleeve is mechanically locked to prevent premature opening during well operations and well life.
