Introduction to Overshot
An overshot is a downhole fishing tool used in the oil and gas industry. Its primary function is to retrieve lost or stuck objects from wellbores. When a drill string, tools, or other equipment get stuck or lost in the well, overshots are deployed to latch onto the object and bring it to the surface. This is crucial for minimizing downtime, reducing costs associated with lost equipment, and ensuring the smooth progress of drilling operations. The design and functionality of overshots have evolved over the years, with modern versions being more efficient, reliable, and adaptable to various well - bore conditions.
