The low temperature oxidation (LTO) process removes oxygen in the injected air, to produce displacement gas (mainly nitrogen) in the reservoir in order to achieve incremental IOR. Reaction and displacement studies on four light oils have been carried out at reservoir conditions. This has involved the high pressure oxidation tube facility at Bath University as well as a small high pressure isothermal reactor.This paper presents preliminary results on the reactivity of the oils studied in terms of oxygen consumption rate at reservoir temperature, and the oil recovery under low rate air injection.P. 479 Keywords: gas injection method, oxidation tube, saturation, reservoir temperature, reaction rate, experiment, enhanced recovery, gas breakthrough, air injection rate, oxidation Subjects: Improved and Enhanced Recovery, Gas-injection methods This content is only available via PDF. 1998.
