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.
Production engineers monitor and evaluate the production and efficiency of an oil or gas well. They develop methods to improve extraction, oversee drilling activities and will determine the need for new or improved tools. One of their main responsibilities is to evaluate the flow between the reservoir and the wellbore. Production engineers monitor the entire production process and will design completion systems and select equipment that will increase production rates. Production engineers are usually petroleum engineers, however sometimes an engineer from a different discipline will be trained on production engineering tasks.
