OPEC-member Qatar has recently hastened development of its natural gas resources, specifically targeting the LNG market, of which the small Middle Eastern country is now the leading exporter. Although the lowest reserve holder among its peers in OPEC, Qatar is estimated to contain more than 15 billion barrels of proven oil reserves as of 2007. The country boasts close to 911 Tcf of proven natural gas reserves, and leading the way in securing and exploiting these resources are Qatargas and Rasgas. Of particular value to the country's natural gas production is the giant offshore North field, or the Qatari extension of the South Pars megaproject, which is the largest gas field in the world.
Petroleum engineers handle many responsibilities, but on a basic level they are responsible for locating, recovering and maintaining the world’s oil and gas supplies. Petroleum engineers design and develop methods for extracting oil and gas from below the earth’s surface. Their duties can also include managing an oil or gas producing property once it is operational and maximizing the performance and profitability of a well. Petroleum engineers are involved in all stages of well production, from helping to locate a potential well site, through drilling, production, processing and transportation. Some job titles a petroleum engineer may carry include reservoir engineer, drilling engineer or production engineer.
