MAGNETIC SENSOR ASSEMBLY FOR ACTUATING A WELLBORE VALVE

摘要

A sensor assembly for actuating a valve comprising: a magnet; and a sensor for the magnet, wherein a tool that is positioned adjacent to the magnet alters the magnetic field of the magnet, wherein the sensor detects the alteration of the magnetic field, and when the sensor detects the alteration, then the sensor actuates a valve to open or close. A method of actuating a valve in a wellbore comprising: positioning the sensor assembly within the wellbore; and running the tool into the wellbore. A system for actuating a valve, the system comprising: a wellbore; the valve; a tool positioned within the casing; and the sensor assembly, wherein the sensor assembly detects the presence or absence of the tool at the location of the magnet, and wherein the sensor assembly actuates the valve to open or close based on the location of the tool.
