The Overshot is the most common and widely used tool in the Fishing Tools family. It is categorized into several series (Series 150, Series 160, Series 70, etc.), with each series designed for specific conditions (depending on the well conditions, type of fish, etc.). The fishing operation with the Overshot tool is a specialized and delicate process, requiring the operator team to have sufficient knowledge and experience with this operation, as well as the well and fish conditions, to select the most appropriate tool and perform the operation in a precise and systematic manner to achieve the goal, which is to remove the fish from the well.

The Overshot consists of various sections, each used under specific conditions. These different sections also involve distinct engineering and manufacturing processes. Nasim Karvarzi Company has extensive experience in designing and manufacturing various types of Overshots (in different series and sizes) for numerous domestic and international clients.
