Petrochemicals are derived from crude oil and natural gas. They are used in the manufacture of end-products such as textiles, plastics and pharmaceuticals. Today, chemical operations account for c5% of global integrated oil company earnings and account for 39% of the world’s chemical market, with the industry producing almost 900 million tonnes of organic chemicals each year. This makes oil companies some of the largest chemical suppliers in the world.
The oil industry’s interaction with the chemical industry began in the 1920s when refiners sought uses for the growing number of by-products from the refining process (principally naphtha); the economics of the industry demanded that every conceivable bit of crude was converted into a usable product.

The chemicals industry is largely defined by the feedstock it uses. The European and Asian chemical industries primarily use naphtha as a feedstock, as this is a readily available refining by-product. By contrast, US and Middle Eastern producers use natural gas or natural gas liquids (NGLs); in the US, this is due to the previously low price of natural gas, and in the Middle East, the widespread availability of very low cost gas. However, following the price increases of natural gas in the US, independent natural gas-fed chemical producers have lost share to naphtha-based suppliers.
