Water Wetting Joint Industry Project

Internal corrosion of oil and gas wells and pipelines made of carbon steel is associated with the presence of water on the pipe surface, a scenario known as water wetting. When the circumference of the pipe is fully coated with oil, corrosion will not occur. Increased knowledge of water wetting and predictive capabilities can increase the confidence of the corrosion engineers and operators on the integrity of pipelines and can decrease the cost associated with corrosion mitigation.

The factors that contribute to water wetting in pipelines are both hydrodynamic and chemical. In general, higher oil flow rates and heavier oils will have a lesser tendency for water wetting. On the other hand, low oil flow rates, light oils and large diameter pipelines are associated with a greater tendency for water wetting. Furthermore, surface active components from the oil, either naturally occurring or added as inhibitors, can alter the wettability of the steel surface, so that it’s less likely to be wetted with water, even under less desirable hydrodynamic circumstances.
