4 Water Chemistry Available to Purchase

Hydrocarbon production is associated with liquid water from a variety of sources. Water is either produced with hydrocarbons or is injected back into a reservoir to enhance recovery or for environmental reasons. Dry hydrocarbon by itself is not corrosive, it is the presence of water, or rather various species associated with the water, that causes corrosion in upstream production systems. Such species include dissolved acid gases, such as CO₂ and H₂S, naturally occurring organic acids, and acids introduced through production chemicals. Furthermore, the salinity and nature of the dissolved ions influence the likelihood and rate of corrosion.
