As it is known, the operation of mature production fields is followed by increase of idling well stock. One of the major reasons for this is the emergency in wells because of the items remained in the wellbore. The field experience justifies the topicality of conducting workovers connected with the removal of such items like geophysical wirelines, traps, cables and wires. Conducting of such works on purpose of well recovery is quite complicated and requires equipment with corresponding tools of workover crew. In this connection, the prospects of increase of fishing works efficiency via improvement of construction and operation principle of used tools have been studied. Offered modification of fishing tools enables to simplify and accelerate conduction of fishing works during well workover.
