Abstract
The present invention relates to methods and equipment for recovering use of a well-bore in circumstances where the well bore has become blocked by downhole equipment. The invention provides a method comprising the steps of separating, at a release joint, a portion of equipment from a jammed portion (6) of equipment; running the separated portion of equipment uphole out of the wellbore (100); running a deflector assembly (60) downhole into the wellbore (100); and deflecting a milling tool (64) from the wellbore into surrounding formation. The method is characterised by restricting relative movement between the deflector assembly (60) and the wellbore (100) by engaging, prior to deflecting the milling tool (64), the deflector assembly (60) with said jammed portion (6) of equipment.
