What is Omans main industry?

The oil and gas industry is the main industry in Oman. Oil was first discovered in Oman in 1962, and the country has been a major oil exporter ever since. The oil industry accounts for about 80% of Oman's government revenue, and it is the country's largest source of foreign exchange. The government of Oman has been working to diversify the economy away from oil and gas, but the oil industry is still the most important sector of the economy.
