The retrievable packer is run slightly below the desired setting position and is then picked up tool to setting position and rotated pipe several turns to right, and on bottom operation, only 1/2 turn is required.Holding right torque in pipe, slack off the pipe weight until mechanical slips on the tool set and start taking weight .At the same time the packer element is compressed against the wall of the casing, then the packer can isolate the annular from the test zone.
