press release Duri Field: The Backbone of Oil Production in Indonesia for 77 years

Jakarta, Indonesia, May 2018 - For 77 years, Duri Field is still delivering best performance as one of major oil producers in Indonesia. Through Steam flood technology, the production of this field is five times higher than the production achieved by the conventional technology. Duri steam flood technology in the first project in Indonesia and one of biggest projects in the world.

“Technology plays pivotal role in determining the success of oil field development and its productive age. Chevron continues investing in developing petroleum technology as well as Enhanced Oil Recovery (EOR) to optimize the oil recovery” stated Sr. VP Policy, Government, and Public Affairs Chevron Yanto Sianipar.

Duri Field is part of the Rokan Block in Riau Province which is operated by PT. Chevron Pacific Indonesia (PT CPI). This field was discovered in 1941 and achieved its first production in 1958, seventeen years after its discovery. Achieving its peak production approximately 65,000 bopd in 1965, Duri Field’s production was decreasing naturally following its reservoir pressure.

PT CPI started the steam flood pilot project in 1975. The technology was implemented in huge scale ten years after that, and it successfully improved the production to 300,000 bopd in 1994. Technology has allowed its achievement. To date, Duri Field produced more than 2.6 billion barrels oil.

PT CPI continues to develop the Duri Field to maintain its contribution to the oil production in Indonesia. The latest developments are North Duri Area 12 and 13 which achieved the first production in 2008 and 2013.

Chevron is one of the world's leading integrated energy companies and through its Indonesian subsidiaries, has been operating in Indonesia for 94 years. With the ingenuity and commitment of highly skilled and dedicated employees, Chevron Indonesia leads as one of Indonesia's largest producers of crude oil. From our onshore oil fields in Riau, Sumatra and our offshore fields in East Kalimantan, we have produced more than 13 billion barrels of oil to meet the energy needs of Indonesia's growing economy.

In operating the oil and gas blocks in Indonesia, Chevron is working under supervision of SKK Migas based on Production Sharing Contract terms. For further information about Chevron in Indonesia, visit www.indonesia.chevron.com.
