As home to supermajors, as well as a plethora of smaller, independent energy players, the US boasts one of the largest concentrations of energy personnel in the world. With its insatiable appetite for energy resources, the United States is the world's single largest consumer of oil, using as much as 20.73 million barrels per day as of 2008. Recently, interest has peaked in the vast quantity of untapped natural gas resources in the US, the reserves of which were inventoried in 2008 at 238 Tcf, with producers specifically targeting the nation's promising shale formations for this energy commodity.
Chemical engineers apply the principles of chemistry to help convert raw materials into useful products. They deal with the design, construction, maintenance and operation of plants and equipment to carry out these procedures. In the oil and gas industry, chemical engineers work to help refine crude oil into useable products such as gasoline and lubricants, and they are also heavily involved in chemical plants and manufacturing operations. Some positions that would require a chemical engineer include process engineer, corrosion engineer and petrochemical engineer, among others.
