ABSTRACT:
A downhole oil well pulling and running tool provides a releasable tool body that can be used to release a workstring such as a coiled tubing string from a tool assembly and to reattach if desired. To reestablish circulations (the ability to pump fluid down the workstring and up the annulus of the well) after detachment by increasing the pressure across a seated ball to a predetermined pressure that forces the ball through the seat into a ball cage. The cage is sized and shaped to carry a plurality of the ball valving members so that the unlatching and relatching procedure may be repeated as many times as desired until the ball cage is filled. Also providing a delay or timing system that will allow debris to pass thru the tool without a release.
