ABSTRACT:
A resettable wellbore tool is provided for running into a wellbore on a workstring, and hydraulically actuating to urge into setting engagement with a wellbore surface. The resettable wellbore tool includes a fluid control member which is resettable between a latched closed position for locking out fluid pressure from the resettable wellbore tool to prevent inadvertent actuation while an operating pressure is applied to a central bore of the workstring, and an open position for passing pressurized fluid into the resettable wellbore tool. The resettable wellbore tool further includes a release latch which is repeatably latchable and unlatchable for releasably securing the resettable wellbore tool to the workstring. The resettable wellbore tool is operable for urging into a setting engagement at a first depth within the wellbore, being released from the workstring, then relatched to the workstring for resetting into the setting engagement at a second depth within the wellbore. The resettable wellbore tool may also be run into the wellbore on a workstring, urged into the setting engagement, and then later released from the setting engagement for retrieval from the wellbore through a production tubing string run into the wellbore subsequent to removal of the workstring from the wellbore.
