Overshot is an external fishing tool for engage, pack off and retrieve tubular fish, especially for fishing drill collar and drill pipe. The grapple of the overshot can be designed for different sizes of fish, so one overshot can be dressed with different size of grapple components for fishing different sizes of fish.
Overshots are essential external fishing tools used in the oil and gas industry to retrieve stuck tubular components such as drill collars, drill pipes, tubing, and subs. They are designed to engage, pack off, and retrieve the fish (stuck pipes or tools) efficiently, reducing downtime and ensuring smooth operations in drilling processes.

Overshots are essential external fishing tools used in the oil and gas industry to retrieve stuck tubular components such as drill collars, drill pipes, tubing, and subs. They are designed to engage, pack off, and retrieve the fish (stuck pipes or tools) efficiently, reducing downtime and ensuring smooth operations in drilling processes.
There are two primary types of overshots:
Short Catch Overshot: Ideal for catching short-length fish when the stuck point is above or near the coupling. It is commonly used for fishing tubing, drill pipes, sucker rods, and subs.
Releasing and Circulating Overshot: Designed to externally fish pipes, including drill collars, drill pipes, tubing, and other tubular components. It allows circulation while retrieving the fish, making it a preferred choice in challenging downhole conditions.
These tools are constructed from high-strength steel, ensuring durability and long-term usability. They comply with API 5DP, API 5B, and GOST standards, providing compatibility with various oilfield applications.
