Naphthenic base oils are a class of oil products refined from naphthenic crudes which have distinct properties that make them useful for industrial applications requiring high performance lubricants. Some key properties of naphthenic base oils include excellent low-temperature fluidity, good thermal and oxidative stability, and good solubility characteristics. In this article, we will provide an overview of the global naphthenic base oil market including production trends, key regions and applications.

Production Trends

Worldwide production of naphthenic base oils was estimated to be around 2.5 million metric tons in 2020. The largest producers have historically been the United States and Canada which have sizeable reserves of naphthenic crudes in regions like Alberta. However, production from North America has been declining in recent years as reserves dwindle. Many refineries in the region have also shifted production capacity to more profitable light refinery streams.

Meanwhile, new production capacities for naphthenic base oils have emerged in other parts of the world. China has significantly ramped up production to meet the demand for industrial lubricants in its growing manufacturing industry. Chinese refineries such as PetroChina Jinzhou Pesticide now have nameplate capacities of over 100,000 metric tons per year of naphthenic base stocks. Russia is another sizable producer with companies like Lukoil promoting exports to Asia and other markets. The Middle East is also emerges as a new hub for naphthenic base oil production with the development of integrated refining complexes having naphthenic crude processing capabilities.

Key Regions and Applications

North America remains the largest regional market forGlobal Naphthenic Base Oil  for over 30% of global consumption volumes in 2020 despite declines in local production. This is due to the region continuing to be a major industrial center with many legacy applications of naphthenic base stocks in sectors such as construction, mining and automotive. However, consumption is shifting towards Asia Pacific which has surpassed North America as the biggest production region for naphthenic base oils.

The industrial engine oils and metalworking fluids segments are currently the largest application areas for naphthenic base oils. Their favorable properties make them well-suited for use in both mobile and stationary heavy-duty engine lubrication. They are also preferred solubilizing agents and carriers in cutting and machining fluids used in industrial metal fabrication processes. Specialty applications such as transformers and hydraulic fluids also utilize naphthenic base oils.
