Corrosion is a natural affinity for metals to return to compounds before reduction. Oxygen corrosion in drilling industry is one of the most important factors in the destruction of metal pipes and equipment. Metals in nature are often in the form of compounds that are thermodynamically stable, lose their stability after reduction, and if they are again in close proximity to the natural environment, they are corroded and return to their original composition.

Corrosion is divided into wet and dry types. The wet corrosion mechanism is electrochemical. However, the dry corrosion is called solid-gas reactions at high temperatures. In the drilling industry wet corrosion is more common.

Corrosion of iron in drilling mud and other fluids are the other types of corrosion in drilling industry. The high electrical conductivity of fluid causes flow current and corrosion rate to increase.
