To further understand and expand the oil resources in Block A, which is located about 130 km off the west coast of Cambodia, Chevron Overseas Petroleum (Cambodia) Ltd. (COPCL) (an affiliated company of Chevron Corporation of the United States) and the Cambodian government signed a joint study agreement (JSA) in 2006. Under the JSA, COPCL was expected to drill five offshore exploration wells in Cambodia in 2006 and an additional five wells in 2007. Block A, which covers a 6,278-square-kilometer (km2) area of the Khmer Basin in the Gulf of Thailand, was owned by COPCL (55%), Moeco Cambodia Ltd. (an affiliate company of Japan's Mitsui Oil exploration Co.) (30%), and South Korea's GS Caltex Corp. (15%).
