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.
Design engineers focus on applying the engineering design process, whereby they develop new or improved products or processes. They are required for projects that are onshore and offshore, upstream and downstream, and can specialize in multiple engineering disciplines including electrical, chemical, mechanical, civil and structural. Design engineers typically complete technical plans using computer-aided design (CAD) software, conduct testing by collecting and analyzing data, and complete regular progress reports for project managers.
