Brunei's small, wealthy economy is a mixture of foreign and domestic entrepreneurship, government regulation, welfare measures, and village tradition.[84] Crude oil and natural gas production account for about 90% of its GDP.[10] About 167,000 barrels (26,600 m3) of oil are produced every day, making Brunei the fourth-largest producer of oil in Southeast Asia.[10] It also produces approximately 25.3 million cubic metres (890×106 cu ft) of liquified natural gas per day, making Brunei the ninth-largest exporter of the substance in the world.[10]
