abbr: combination of forward combustion and water flooding. Also called wet combustion.

a tertiary recovery mechanist consisting of combustion and water flooding.

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.

abbr: ethyl tertiary butyl ether.

n: (ETBE) a compound of ethanol and isobutylene. Compare methyl tertiary butyl ether.

a tertiary recovery method involving injection of air into the formation and igniting the oil. Under the right conditions, the heat produced from combustion of the heavy ends that are trapped on the sand grains lowers the oil viscosity and liberates light

a tertiary recovery operation, consisting of first injecting steam, followed by flowing the well back to recover oil that has had its viscosity reduced by application of the heat.

n: (MTBE) leadfree antiknock compound added to gasoline. Compare ethyl tertiary butyl ether:

abbr: methyl tertiary butyl ether.

methyl tertiary butyl ether.

adj: 1. of or relating to the geologic epoch from about 2.5 million to 10 thou- sand years ago, the first part of the Quaternary period of the Cenozoic era, sometimes called the Ice Age, which extended from the end of the Tertiary period until the last re- treat of the northern continental ice sheets. 2. of or relating to the rocks or sediments formed during this epoch.

n: see recovery efficiency.

the percentage of the hydrocarbon in place that can be produced with each production plan: primary, secondary and tertiary.
