Wettability : A major factor in oil and gas system corrosion

Wettability can be the determining factor in the occurrence of corrosion in oil and gas systems but is little understood in the corrosion industry. Factors involved in determining the oil vs water wettability of metal and corrosion product surfaces are presented. The data are applied to corrosion under producing well and production equipment conditions to estimate when to anticipate corrosion, how corrosion inhibitors affect wettability, and the effect of wettability on corrosion rates.
