Enhanced Oil Recovery. Secondary and tertiary techniques for recovering crude from a pool. Oil is recovered other than by the natural pressure in a reservoir. These methods increase the proportion of oil recovered, but at additional cost.
Enhanced Oil Recovery. The recovery of hydrocarbons from a reservoir other than by the use of natural reservoir pressure. This can involve increasing the pressure (secondary recovery), heating or increasing the pore size of the reservoir (tertiary recovery).
Enhanced Oil Recovery. The use of any process for the displacement of oil from the reservoir other than primary recovery.
Enhanced Oil Recovery. The introduction of an artificial drive and displacement mechanism, usually steam, into a reservoir to produce oil unrecoverable by primary and secondary recovery methods.
Enhanced oil recovery. Refers to a variety of processes to increase the amount of oil removed from a reservoir, typically by injecting a liquid (e.g., water, surfactant) or gas (e.g., nitrogen, carbon dioxide).
Enhanced oil recovery. Any method that increases oil production by using techniques or materials that are not part of normal pressure maintenance or water flooding operations. For example, natural gas can be injected into a reservoir to "enhance" or increase oil production.
Enhanced Oil Recovery. Increased production of oil from an oil field, brought about by injecting gas (eg CO2) or water to raise the oil pressure and force more oil out.
Enhanced Oil Recovery. advanced technologies, such as water flooding, steam injection, CO2 injection applied to increase production, usually from mature, underdeveloped fields.
Enhanced Oil Recovery. Injection of steam into oilholding geologic zones to increase ability to extract oil by lowering its viscosity. Also used to designate a special category of gas customers.
