Influence of reservoir rock composition on the combustion kinetics of crude oil

In this research, the effect of different lithology (limestone and sandstone) on the combustion of light crude oils was investigated using thermal analysis techniques. Three distinct reaction regions were identified in all of the crude oil+limestone and sandstone mixtures, known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO), respectively. Kinetic analysis of the crude oil+limestone and sandstone mixtures was performed using Coats and Redfern method and the results are discussed.
