GS-type well‑running/retrieval tool

The GS‑type running/retrieval tool is used to run in and retrieve downhole tools equipped with a standard internal retrieval neck. By varying the pressure, it actuates the key blocks and mandrel to effect release. This tool eliminates the need for shear pins or ball‑dropping; instead, it releases the slip assembly through differential pressure cycling.
