Executive Summary

The Wireline Spear is a downhole tool used to retrieve lost or compacted wireline in oil and gas wells when a standard two-prong wireline grab cannot engage it. The tool’s body has upward-pointing barbs or slips that penetrate and anchor into the wireline, allowing it to be pulled to the surface.

It is primarily used in fishing operations to recover badly balled-up or entangled wireline, providing a controlled and secure method for wireline retrieval.

Detailed Description

The Wireline Spear is a downhole tool used in oil and gas wells to retrieve lost, broken, or compacted wireline that cannot be engaged with a standard two-prong wireline grab. It is designed for fishing operations where the wireline has become badly balled up or tightly compacted, situations where conventional pronged grabs are ineffective.

The tool is deployed on a wireline and guided down the wellbore under its own weight. Its central mandrel is surrounded by upward-pointing barbs or slips that penetrate and anchor into the wireline. When engaged, these barbs provide a secure grip on the wire, allowing the tool and wire to be retrieved to the surface.

The Wireline Spear is designed for maximum penetration into tightly balled or compacted wire. Its barbs ensure engagement even when the wire is severely entangled. Because the Wireline Spear is effectively non-releasable, it is typically run with a disconnect arrangement above the tool. This allows the assembly to be released if the wire cannot be recovered fully, preventing the tool from becoming stuck in the wellbore.

The tool is available in sizes from 1.5” to 3.5”, with a maximum outside diameter of 1.500” to 3.500” and a fishing neck O.D. of 1.375” to 2.312”. It connects to the wireline through a top connection ranging from 15/16 – 10 UN to 1-1/16 – 10 UN and can retrieve wire diameters from 0.50” to 3.50”.

The Wireline Spear is constructed from steel to withstand downhole mechanical stresses and pressures. Its design includes a central mandrel with upward-pointing barbs that secure tightly compacted or balled-up wireline. The tool’s compact dimensions and engagement mechanism allow it to retrieve wireline that cannot be captured by standard pronged grabs, and it is generally run with a disconnect arrangement above the tool to allow release if the wire cannot be recovered.
