Harvesting an abundance of oil and natural gas resources, the Middle East supplies nearly half of all exports to the global oil market. Middle Eastern countries Iran, Iraq, Kuwait, Qatar, Saudi Arabia and the United Arab Emirates are all members of the Organization of the Petroleum Exporting Countries (OPEC), which pumps roughly 40% of the world's oil, with Saudi Arabia leading the pack for the greatest amount of output. OPEC's crude oil production was 28.7 million barrels per day in the first half of 2009.
Chemists specialize in the composition, structure, properties and reactions of substances. Chemistry can be found throughout the industry, whether it is developing drilling fluid to pump down the wellbore or developing catalysts for use in refining. Chemists may analyze data in an office environment, perform experiments in laboratories, or review processes in the field.
