Indonesia

Proved recoverable reserves (crude oil and NGLs, million tonnes)	570
Production (crude oil and NGLs, million tonnes, 2005)	54.0
R/P ratio (years)	10.6
Year of first commercial production	1893

The first commercial discovery of oil was made in north Sumatra in 1885; subsequent exploration led to the finding of many more fields, especially in southern Sumatra, Java and Kalimantan.

Proved recoverable reserves at end-2005 have been based on published data, and reflect the consensus view of Oil & Gas Journal, OAPEC, OPEC and BP, at a level of 4 300 million barrels. World Oil, while ostensibly excluding NGLs, quotes a significantly higher figure at 5 025 million barrels.
In 2004 Indonesia exported over 40% of its output of crude oil and condensate, as well as about half of its production of gas-plant LPGs. The bulk of its oil exports are consigned to Japan, the Republic of Korea, Australia and China. It has been a member of OPEC since 1962.
