NACE RP 0775: A Standard for Corrosion Coupons in Oilfield Operations
Corrosion is a major problem in the oil and gas industry, as it can cause equipment failure, production loss, environmental damage, and safety hazards. To monitor and control corrosion, various methods and devices are used, such as corrosion coupons, probes, instruments, chemical analysis, and nondestructive testing. Among these, corrosion coupons are one of the most widely used and cost-effective techniques for evaluating the corrosiveness of various systems and the effectiveness of corrosion mitigation programs.

Corrosion coupons are small specimens of metal that are exposed to an environment of interest for a period of time to determine the reaction of the metal to the environment. They can provide information on the general corrosion rate, uniformity of corrosion, pitting tendency, and scale formation. Corrosion coupons can be used in oilfield drilling, production, and transportation operations, including oil-, water-, and gas-handling systems, and drilling fluids.
To ensure the reliability and accuracy of corrosion coupon data, proper preparation, installation, analysis, and interpretation of corrosion coupons are essential. NACE International, the worldwide corrosion authority, has developed a standard recommended practice for this purpose: NACE RP 0775-2005. This standard provides guidelines and recommendations for the use of corrosion coupons in oilfield operations, covering aspects such as coupon selection, handling, placement, retrieval, cleaning, weighing, calculation, and reporting.
NACE RP 0775-2005 is a revision of the previous edition published in 1999. The main changes include the addition of information on coupon holders and retrievers, coupon cleaning methods and equipment, coupon mass-loss determination methods and equipment, coupon data recording form and example calculations, and references to other NACE standards and reports related to corrosion coupon testing. The standard also clarifies some terms and definitions, such as corrosion rate units and coupon exposure time.
NACE RP 0775-2005 is available for purchase from the NACE International web store. However, some websites offer free downloads of this standard in PDF format. Users should be aware that these websites may not be authorized by NACE International and may contain outdated or inaccurate versions of the standard. Users should also respect the intellectual property rights of NACE International and comply with its terms and conditions for using its standards.
Corrosion coupon testing is a valuable tool for assessing and managing corrosion in oilfield operations. By following the guidelines and recommendations in NACE RP 0775-2005, users can obtain reliable and meaningful data that can help them optimize their corrosion control strategies and improve their operational performance.
