Wireline Tool Recovery In Case of Wireline Tool Stuck

Wireline tool such as logging tool, slick line tool can be stuck in the hole therefore we need to understand about wireline recovery tool. This article demonstrate typical wireline fishing / recovery tool.  Common wireline tool issues center around the cable being tangled or wadded in the hole, as well as the fact that attempts at fishing can pull the wireline out of the rope socket or part, further complicating tool retrieval.

Stuck Cable or Tools

As soon as a wireline assembly becomes stuck, the operator will need to determine whether the problem is in the cable or the tool. Usually, one would apply normal logging tension on the cable and allow it to sit for a few minutes. During this time, four things should be recorded:

  1. the current depth of the tool
  2. the type and size of the cable
  3. the surface tension of the cable just prior to becoming stuck
  4. the cable-head’s weakpoint rating

Well Flowing After Disconnecting The Wireline Lubricator – Well Control Situation

Please watch the footage below. It was a flow back after breaking out the lubricator on the rig floor.

We don’t know full details what was happened but from what we’ve seen in this VDO, it shown that the well was flowing after the wireline operation was completed. The crew broke out the connection between the wireline lubricator and the string set on the rotary table.  Few seconds after the connection was removed, the well flowed back. The flow became stronger as you can see the drilling fluid was pushed out from the drillstring quickly and the rotary table started to turn black. The lubricator was pushed by hydraulic power from the mud and it was swung around. Eventually, the crew went back to connect the lubricator to the string and the well stopped flowing.  It seem like the situation was under control at the end. Luckily, there was no gas or any spark that can cause fire on the rig floor.
