Certain crude oils contain long-chain naphthenic and carboxylic acids. As production fluids depressurize, certain compositional changes lead to a reaction between these acids and metal ions in produced water. Insoluble salts such as naphthenate and carboxylate soaps and scales are formed.
Schlumberger has developed proprietary technology covering application methodology and high-performance nonacidic naphthenate inhibitors, which provides a highly effective approach to your specific needs.
Laboratory test methodologies are based on the proposed type of naphthenate treatment required to meet the desired results. Factors that must be considered include field pressure, field temperature, and fluid characteristics.
Our field monitoring techniques encompass treatment economics and effectiveness, as well as environmental and safety issues.
