  • Patent number: 9810034
    Abstract: A tool equalizes a packer or bridge plug before it can release the slips and sealing element of the packer or bridge plug with a reconfigurable grip tool. In one configuration the grip tool is latched only into the equalizing mechanism for the packer or bridge plug. Having equalized the pressure and while still latched to the equalization mechanism the tool is reconfigured with a force and locked into a second configuration. From that position the grip tool can latch and move the release mechanism for total release and retrieval to the surface. Release force undermines a ratchet lock for the slips to allow extension as the sealing element extends axially and radially retracts. If the slips fail to release with undermining of the ratchet lock then a set down force can be applied to re-engage the lower slip cone to push it from the lower slips for a release.
