Saudi Aramco is the Middle East's largest refiner.

Meeting demand requires extensive, integrated manufacturing and transportation systems. A kingdom-wide network of refining, supply, and distribution facilities, staffed by highly trained personnel, maintains this continual supply of refined products.

Saudi Aramco's four domestic refineries, at Riyadh, Ras Tanura, Yanbu' and Jiddah, have a combined capacity of nearly 1 million barrels per day. Adding the company's two domestic joint-venture refineries, with ExxonMobil in Yanbu' (SAMREF) and with Shell in Jubail (SASREF), and the company's share of refining capacity at Petro Rabigh, brings in-Kingdom refining capacity to roughly 2.1 million barrels per day.
