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.
A drilling engineer’s main responsibility is to manage the drilling of a well to produce oil or gas as safely and efficiently as possible. Drilling Engineers are involved from the initial well planning and design, through well testing, completion, and finally abandonment. Designing and maintaining the equipment used for oil and gas extraction is another one of their responsibilities, as well as performing cost estimates and keeping track of drilling rates. Drilling engineers work in both the office and the field, which could be either onshore or offshore. Generally drilling engineers complete an engineering degree in petroleum, mechanical or chemical engineering.
