The Slickline allow the lowering and / or retrieving of tools in a alive well (under pressure) through the use of a special steel wire (harmonic) with a diameter of 0.108"-0.125"-0.140".
The tools run can be instruments for measuring well data (i.e. pressure and temperature), for manipulation of well components (safety valves, circulation valves, plugs, etc.) or for well intervention (i.e. fishing operation).
The tool string (composed of rope socket + stem weight bars + jar + tool specific for the operation to be performed) is connected to the wire after it has been passed through the stuffing box and then inserted in the lubricator; all is raised and connected to the BOP on top of the wellhead.
At this point, the well can be opened and the operation carried out in the conditions of maximum safety.
