Oil and Natural Gas is the main source of wealth in Brunei.  

Explanation:

According to International Monetary Fund (IMF), Brunei was ranked as the fifth by Gross Domestic PerCapita in the world in terms of purchasing power.  The population of Brunei is less than 5 lakhs. The major expenses of the citizens are taken care by the Sultan's Government for education and healthcare. The 99 percent of the exports in the country are from the oil and natural gas. It is the smallest yet the richest country ruled by the Sultan family since centuries. The high standard of living and the massive wealth is due to the rich deposits of oil and gas.
