  • Work Principle of XJ250 Workover Rig
  • Workover begins by removing the wellhead, then lifts the tubing hanger from the casing head, thus begins to pull the completion out of the well. The string will be always fixed in place by at least one production packer. If the packer is retrievable it can be released easily enough and pulled out with the completion string. If it is permanent, then it is common to cut the tubing just above it and pull out the upper portion of the string. If necessary, the packer and the tubing left in hole can be milled out, though more commonly, the new completion will make use of it by setting a new packer just above it and running new tubing down to the top of the old.
