Abstract: This study proposes reaction pathways to explain chemical routes that the fractions of a heavy crude oil follow during the thermal cracking and low temperature oxidation stages of in situ combustión (ISC). ISC is an enhanced oil recovery method that has as operating principle a combustion process inside a reservoir. Coke is produced during this process by thermal cracking and oxidation at low temperature and reacts to release energy in the form of heat that reduces the viscosity of ...
