A Magnesium Alloy Anode for Oil Well Casing is a sacrificial (galvanic) anode specifically designed to provide cathodic protection (CP) for oil well casings and downhole tubular structures. Installed along the casing string or in the surrounding formation, the anode protects steel casing from corrosion caused by soil, groundwater, and formation fluids.
