n: (EOR) 1. the introduction of artificial drive and displacement mechanisms into a reservoir to produce a portion of the oil unrecoverable by primary recovery methods. To restore formation pressure and fluid flow to a substantial portion of a reservoir, fluid or heat is introduced through injection wells located in rock that has fluid communication with production wells. See alkaline (caustic) flooding, gas injection, micellar-polymer flooding, primary recovery, secondary recovery, tertiary recovery, thermal recovery, waterflooding. 2. the use of certain recovery methods that not only restore formation pressure but also improve oil displacement or fluid flow in the reservoir. These methods may include chemical flooding, gas injection, and thermal recovery.

one or more of a variety of processes that seek to improve recovery of hydrocarbon from a reservoir after the primary production phase.

n: the introduction of artificial drive and displacement mechanisms into a reservoir to produce a portion of the oil unrecoverable by primary recovery methods. See enhanced oil recovery.

microbial enhanced oil recovery.

abbr: thennal enhanced oil recovery.

thermal enhanced oil recovery.

n: (TEOR) a method of increasing well productivity and recoverable oil by using heat, e.g., steam injection (the huff n puff method),steam flood, or in situ combustion.

n: a type of improved recovery in which heat is introduced into a reservoir to lower the viscosity of heavy oils and to facilitate their flow into producing wells. The pay zone may be heated by injecting steam (steam drive) or by injecting air and burning a portion of the oil in place (in situ combustion). See cyclic steam injection, in situ combustion, steam drive.

an enhanced oil recovery process that uses heat to reduce oil viscosity.
