Saudi Aramco is working with Chinese oil and petrochemical company Sinopec to find and develop gas reservoirs as part of the Kingdom of Saudi Arabia's Upstream Gas Offering. The exploration activities are taking place in Contract Area B, an approximately 40,000-square-kilometer area in the Kingdom's Rub' al-Khali Basin.
To explore Contract Area B, Sinopec and Saudi Aramco have formed an exploration and producing company, Sino Saudi Gas Limited, with Sinopec holding 80 percent of the company and Saudi Aramco 20 percent.
Sinopec is a vertically integrated energy and chemical company. It is China's largest producer and marketer of oil products (both wholesale and retail of gasoline, diesel, jet fuel), and No.1 supplier of major petrochemical products (intermediates, synthetic resin, synthetic fiber, synthetic rubber, fertilizer), as well as the 2nd largest crude oil producer.
