Abundant and competitively priced petroleum feedstock has driven massive growth in Saudi Arabia's chemicals industry over a period of time. The chemicals industry relies on the tremendous amount of hydrocarbons in the Kingdom, including gases and liquids associated with crude oil production and methane production. Leading international companies such as Saudi Arabian Basic Industry Co. (SABIC), Petro Rabigh, Tasnee, and others, which are publically traded on Tadawul, the Saudi stock exchange, have produced excellent results for their shareholders.
