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.
Modeling is used in engineering to develop data as a basis for technical or managerial decisions, through the use of simulations. Typically, by using advanced software that provides state-of-the-art visualization and analysis capabilities, engineers are able to decide the best processes and strategy moving forward. Accurate modeling reduces the time, cost and risk involved by being able to run multiple scenarios conceptually through a computer program.
