What does a fishing tool do in the oil field?

A fishing tool in the oil field is used to retrieve lost or stuck equipment from a wellbore, such as drill bits, casing, or other tools. These tools are designed to grip and extract objects that are no longer functional or have fallen into the well, helping to minimize downtime and restore operations. Fishing operations are critical for maintaining efficient oil extraction and ensuring the integrity of the well. Various types of fishing tools are available, each tailored for specific recovery challenges.
