Indonesia has seven refineries, with a combined capacity of 992,745 bbl/d. The largest refineries are the 348,000-bbl/d Cilacap in Central Java, the 240,920-bbl/d Balikpapan in Kalimantan, and the 125,000-bbl/d Balongan, in Java. 
PT Kilang Minyak Intan Nusantara, a joint venture of Al-Banader International Group of Saudi Arabia (40%), China National Electrical Equipment Corporation (40%) and PT Intanjaya Agromegah Abadi (20%), are planning to invest a total of $3 billion to build a refinery at Pare-Pare, South Sulawesi. It would be export oriented, taking Saudi crude and refining it for sale primarily to the Chinese market. Iran also has been discussing the possibility of financing an export-oriented refinery in Indonesia, which would process Iranian heavy crudes for export into Asian markets.

Pertamina has decided to resume construction of the partly built petrochemical facility in Tuban, East Java. The project has been stalled since 1998, but a joint venture was established in September 2005 between Pertamina and Sinopec of China to conduct a feasibility study on completing the plant.
