As we know, fishing operations for Lost slickline/wireline toolstrings present a real challenge with conventional fishing tools since in many cases a top fish is lined on casing wall in well bottom.
This tool is designed and developed to lower underneath a slickline fishing tool (pulling tool, overshot…), once below the end of tubing the tool can be activated, oriented to casing wall and allowed 360 degree of mechanical angular rotation for a fishing to find a top of the fish. The tool allows a jarring down action to latch on top of fish, then thanks to its robustness can support a high jarring up impact to retrieve the fish. On the way up the tool can be retracted to move inside the tubing.
