The workover procedure is a reversal of the completion running (i.e., a suspension plug is installed in the production packer tailpipe, and the well is lubricated to kill fluid). After retrieving the completion, the packer-picking assembly is run to the packer depth, and the well is returned to an underbalanced condition prior to retrieving the packer. This ensures that formation-damaging kill fluid does not come into contact with the reservoir at any time.

The workover procedure is a reversal of the completion running (i.e., a suspension plug is installed in the production packer tailpipe, and the well is lubricated to kill fluid). After retrieving the completion, the packer-picking assembly is run to the packer depth, and the well is returned to an underbalanced condition prior to retrieving the packer. This ensures that formation-damaging kill fluid does not come into contact with the reservoir at any time.
