PMI Pin

A PMI pin refers to the magnetic position indicator pin used in drilling operations, especially in oil and gas extraction. It’s a small, precise marker placed within a drill pipe or tool to help engineers and technicians track the position and orientation of equipment downhole. By analyzing signals from the pin, they can determine the tool's exact location and movement inside the wellbore. This aids in accurate drilling, avoiding hazards, and ensuring the well is drilled according to plan. Essentially, a PMI pin is a reliable way to monitor and control downhole tool positioning during complex drilling processes.
