Processes for secondarily recovering oil
TLDR
A secondary recovery process using injected air to pressurize the formation and maintain mobility of the reservoir oil by diluting the oil with carbon dioxide is described in this article. But this method is limited to the case where the oil cannot be ignited by auto-oxidation.Abstract:
A secondary recovery process using injected air to pressurize the formation and maintain mobility of the reservoir oil by diluting the oil with carbon dioxide. Carbon dioxide is produced as a by-product of air injection, either by auto-oxidation of carbonaceous materials in the reservoir rock, or by ignition of oil in the reservoir. Efficiency of oxidation is observed by testing O 2 content of the effluent gas; it is desirable to hold the oxygen content in the effluent gas to less than 3% by volume in the effluent gas. When this content cannot be reached by auto-oxidation, it is necessary to ignite the oil.read more

Method of recovering hydrocarbons by in situ combustion
TL;DR: In this paper, a passageway is established from a point in the formation, through same, and to the surface of the ground to recover hydrocarbons and other chemicals from a coal stratum and/or from an oil sand.
