What are the oil and gas jobs in Indonesia, particularly in Jakarta Indonesia? I heard that Indonesia became a net importer of oil in 2004 and is estimated to contain more than 4 billion barrels of proven oil reserves, as of 2007. Indonesia's oil sector is controlled by several international oil companies, including supermajor Chevron, which pumps from the country's two largest oil fields, Minas and Duri, along Sumatra's coastline. I believe it is promising to work here. What are the possible positions I can apply for?
