Material selection to get “fit-for-purpose” alloys is an important task that corrosion engineers face in their daily work. Two common ways of attacking such a challenge is by testing different alloys in environments similar to the application in a laboratory environment or installing samples in actual operating equipment. In the latter, testing is usually time consuming and might require plant turnovers to get access to the equipment for sample installation.

Parameters reported in production fluid water chemistry analyses are used by engineers for determination of scaling tendency and corrosivity, thus promoting optimal production rates while maintaining asset integrity. Water chemistry analysis documents report ion concentrations, total alkalinity, and various graphical data sets related to the tested brine which are designed to assist field engineers. The alkalinity value provided in these documents is of utmost importance to corrosion engineers as it is a measure of the capacity of an aqueous solution to resist changes in acidification. Alkalinity can also be directly linked to the in situ pH of the produced brine and can therefore provide key inputs to assess and predict its corrosivity. Yet, including alkalinity into corrosion production models can be challenging considering there is still much uncertainty among operators about the validity and meaning of the reported alkalinity value. For that reason, recent publications (two AMPP standards) have focused on providing additional guidelines to those who need this knowledge. This is of key importance for the optimization of appropriate and economic corrosion and scaling mitigation strategies. This paper will review the use of the alkalinity term and water chemistry analysis with goals of minimizing confusion and optimizing the use of proper data input for corrosion prediction models.
