The infrared spectroscopy has been used for characterisation of EOM, asphaltenes and crude oils of the Cambay basin. The functional groups of EOM, asphaltene and crude oil were characterised and extinction ratios at maximum wave numbers of the respective groups were calculated. On the basis of these data, the type of EOM, its evolution path and original organic matter of Cambay basin have been identified.
