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.
Geologists apply their knowledge of the earth and its structures to help find and extract oil and gas. Although geologists are usually tied to the location of deposits, they are involved in all aspects of discovery and production. Geologists look at structure and sediment, as well as interpret other geophysical information to help make decisions on where to drill. They must understand the origin, amount and movement of oil as well as any obstacles that may be in the way of deposits before drilling can begin. Geologists will help find deposits all over the world including on land and under the ocean. A strong geoscience background is required for these types of positions.
