Wellbore recovery operation

摘要

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.
