Note générale :	Preliminary studies of three widely separated wells tapping the middle zone aquifer of the chad formation in the bornu and sikwa emirates of ortheastern Nigeria suggest that serious corrosion of iron and sceel well parts is likely to occur throughout this ground - water system. The relatively low oxidation reduction potentials and PH values and the relatively free carbon dioxide contents revealed by these testo are extremely destrustive to ferrous metal components. It would be impracticable to prevent corrision of weel parts by chemical treatment, metal coatings, or carthdicprotection in such an aqueaus environnement, and particulary at these relatively remonte well sites.
