Traditional methods of oil extraction have been the primary and secondary methods, which, according to studies by the US Department of Energy, only exhaust between a quarter and half of a well's oil reserves. Such profligacy has been addressed by the development of a tertiary technique, more commonly known as enhanced oil recovery (EOR).
