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.
Maintenance engineers apply engineering concepts in order to achieve better maintainability and reliability of machinery and equipment in the most efficient ways possible. They will use statistics, probability and logistics to solve problems, as well as use lean six sigma principles in order to optimize the maintenance process. Maintenance engineers have a number of responsibilities including conducting periodic inspections, performing system upgrades and changes, troubleshooting equipment issues and determining when repair and replacements need to take place. Maintenance engineers generally have a bachelor’s degree in engineering or applied science, and can be found in almost every aspect of the oil and gas industry.
