Primary oil recovery is just the first option available to the oil-exploration industry. There are also secondary and tertiary recovery methods, sometimes referred to as enhanced oil recovery. These methods make it possible to access another 40 percent of a reserve's crude supply, and as oil prices increase so, too, does the justification for employing more complex methods. Tertiary recovery is also known as enhanced oil recovery (EOR) and is the third phase of oil extraction from an oil reserve. This phase of removal allows petroleum companies to remove a significant amount of oil from a reserve which they would not be able to access without these enhanced methods. Secondary recovery techniques extend a field's productive life generally by injecting water or gas to displace oil and drive it to a production wellbore, resulting in the recovery of 20 to 40 percent of the original oil in place.

With the decline in oil discoveries during the last decades it is believed that EOR technologies will play a key role to meet the energy demand in years to come.

Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface. Enhanced Oil Recovery – or EOR – is the process of increasing the amount of oil that can be recovered from an oil reservoir, usually by injecting a substance into an existing oil well to increase pressure and reduce the viscosity of the oil[1]. With a conventional oil well, natural pressure in the reservoir pushes
