I've run a lot of retrievable bridge plugs in wells and I've learned that if you run them enough you will eventually find yourself in a situation where you can't latch onto the plug. In case you're not familiar with retrievable plugs, they are retrieved by running back into the well and latching onto a "fish neck" which is basically a metal rod that can be latched on to. This is a straight-forward process most of the time, until something falls on top of it (debris, trash, flange bolts, gloves, etc.). When this happens, a very simple process of latching onto a plug can become long and drawn-out, and sometimes requires much more robust and expensive equipment. However, there is a very simple preventative measure - run a junk basket.
A junk basket is a simple tool that sits on top of a plug and catches all of the "junk" so that it doesn't land on your plug. It requires an extra wireline run which will add slightly to the cost. But do you know what's way more expensive than a junk basket run? Getting a stuck plug unstuck because of a silly piece of trash downhole.
As I said, I've run a lot of retrievable plugs and I've never had an issue getting the plug out when a junk basket was run. I have however had issues on occasion when someone wanted to save a buck and not run a junk basket. The moral of the story here is to spend a tiny bit of extra money and run a junk basket. Your future self will thank you for not cutting corners.
