Naphthenate management
Calcium naphthenate is one of the concerns in production chemistry which may plug pro-
duction systems and process equipment. Naphthenate precipitates when naphthenic acid re-
acts with metal ions such as calcium or sodium.
Properties of naphthenates
Naphthenate density ranges between water and oil densities. Naphthenates may collect at
oil-water interface and behave as surfactants by stabilizing emulsions.
