Abstract

The seeded crystal growth experiment has been examined as to its applicability for investigating the growth and inhibition of water-born deposits. Basic and practical aspects of the experiment are reviewed in this paper, and examples are cited to demonstrate experimental capabilities. In one of the examples, it is shown that the experiment can be conducted in a natural oil-field brine to resolve small differences in inhibitor performance. It is concluded that the seeded crystal growth experiment is the best available procedure for characterizing unstable waters where reproducibility and reliability are of major importance.
