Abstract:
A method of displacing a tubing string in a well bore of a well, the tubing string being mounted to a wellhead and including a locking telescoping joint, comprising the steps of:a) inserting a lift rod string through the wellhead and latching the lift rod string to a latch point in the telescoping joint; b) manipulating the lift rod string, if required, to release the locking telescoping joint to permit the locking telescoping joint to be extended or retracted; c) manipulating the lift rod string in an axial or a radial movement to correspondingly displace the tubing string; and d) manipulating the lift rod string to lock the locking telescoping joint in one of a plurality of predetermined axial extensions, so that the tubing string is secured as displaced after displacement is completed.
