Abstract
A wireline fishing tool is disclosed including a body, a side prong extending from a lateral side of the body, and a central prong extending from a center of the body. The central prong is movable relative to the body between an extended state and a retracted state. The central prong comprises a toothed shaft retractable with respect to the body to move the central prong from the extended state to the retracted state and a tooth movable relative to the toothed shaft between a stowed state in which the tooth is disposed within the toothed shaft and a deployed state in which the tooth extends from the toothed shaft. The tooth is movable from the stowed state toward the deployed state based on the central prong moving from the extended state to the retracted state.
Claims15
A wireline fishing tool, comprising:
- a body;
- at least one side prong extending from a lateral side of the body;
- and
- a central prong extending from a center of the body and movable relative to the body between an extended state and a retracted state, the central prong including:
- a toothed shaft retractable with respect to the body to move the central prong from the extended state to the retracted state;
- and
- a tooth movable relative to the toothed shaft between a stowed state, in which the tooth is disposed within the toothed shaft, and a deployed state, in which the tooth extends from the toothed shaft,
- wherein the tooth is movable from the stowed state toward the deployed state based on the central prong moving from the extended state to the retracted state.
A method, comprising:
- conveying a wireline fishing tool into a wellbore and encountering a wireline fallen within the wellbore;
- radially compressing the wireline into the wireline fishing tool by engaging the wireline with at least one side prong of the wireline fishing tool based on the wireline fishing tool being conveyed downwardly through the wellbore;
- driving a central prong of the wireline fishing tool from an extended state toward a retracted state;
- and
- pulling the compressed wireline upwardly with the central prong based on the central prong moving toward the retracted state.
