Packer Picker–Latch Type
TheWellEnTechPacker Picker is designed to be used in conjunction with a washover shoe or bladed style of packing milling device. This Packer Picker is designed to catch a profile or bottom end of a Packer and prevent the bottom end of the packer falling when the element and slips have been milled. The Latch is free to rotate on the mandrel, which allows the Latch to remain stationary during the milling operation.There is an emergency shear release mechanism enabling the packer picker to be released from the Packer fail to release after milling.

Operation
TheWellEnTech Packer Picker is run down through the Packer bore and is spaced out so that the latch is fully out of the bottom of the Packer when the Bladed Mill or Overshot tags the top of the Packer. The Packer Picker is supplied with a dressed Mill Sub to clear any bore obstructions when running into the Packer bore. Once in position, milling of the Packer can commence. Once the desired amount has been milled, the drill string can be picked up, resulting in the latch contacting the bottom of the Packer and enabling the Packer to be retrieved. If however the Packer fails to release, the Packer Picker can be released by applying a predetermined over pull, shearing the Shear Ring and allowing the latch to collapse and pull up through the Packer bore.
