The Seram Non-Bula Block is located on Seram Island, Indonesia and covers an area of about 4,572 square kilometres. The principal field in the Seram Non-Bula Block is the Oseil Field. The Oseil field is located in the Seram Non-Bula PSC area on the island of Seram about 300 kilometers east of the city of Ambon. The field is located inland from the northeast coast of the island. As at 31 December 2009, the Seram Non-Bula Block had estimated proved oil reserves of 8.7 million barrels. The average production in 2009 was about 2,300 barrels per day (gross) of 15° to 22° API oil. Discovery of the Oseil Field occurred in 1993 with the drilling of the Oseil-1 well, which found oil-bearing sections within the Manusela Carbonate. Since that time, nine additional wells, both vertical and horizontal, have been drilled to develop the field and have identified oil-bearing Manusela accumulations in four separate closures. Currently, oil has been produced from three of the four fault block closures. In the period from 1988 to 2002, the operator has drilled four exploration wells in the Seram Non-Bula Block, resulting in commercial oil discovery in the Oseil Field. On 23 November 2006, CITIC Seram (an indirect wholly-owned subsidiary of the Company) completed the acquisition of a 51% participating interest from KUFPEC. As of the same date, CITIC Seram became the operator responsible for the day to day petroleum operations at the Seram Non-Bula Block. As the operator of the Seram Non-Bula Block, CITIC Seram is expected to maintain and improve current production levels at the Oseil Field on an economic and efficient basis in order to maximise output at the Oseil Field. Under the Production Sharing Contract, the Contractor (collectively the participants other than BPMIGAS namely CITIC Seram, KUFPEC, GPI and Lion) has been granted a 100% right to explore, develop and produce oil from the Seram Non-Bula Block for a period of 20 years until 2019.
