1. n. [Drilling Fluids]

In chemical analysis, a procedure to determine the amount of a constituent in a sample by adding a measured volume of reagent until the reaction between the constituent of interest and the reagent is completed, as shown by an appropriate endpoint indicator. For mud and mud filtrate analyses, titration is a common procedure for determining alkalinity, chloride, total hardness, methylene blue capacity and formaldehyde.
