Wet combustion: a tertiary recovery process for light oil
Wet combustion has been recognized as a potential tertiary recovery process. Very little data are available on laboratory and field tests of its application to high - gravity crude oil. This study presents results of one dry and four wet combustion tests in water - flooded sand packs with high-gravity crude oil. Crushed native core samples were used for the tests and pre-burn fluid saturations established by flooding. X-ray diffraction analysis techniques were used to determine changes in mineral compositions. These changes were used to correct product gas analyses and all calculations using product gas compositons for carbon dioxide produced from decarbonation reactions. The effect of injected water air ratio on injected air-produced oil ratio, oil recovery efficiency and combustion front velocity are presented.
