Abstract

•The effectiveness of applying urea as a gas generating agent in in-situ CO2 EOR is proved.•Urea shows better divalent cations tolerance than previously studied gas generating agent (ammonium carbamate).•In-situ CO2 Generation EOR has better performance with lighter crude oil.•Operating above the MMP is not a necessary criterion for achieving high tertiary recovery of in-situ CO2 EOR.•Oil composition change in the recovered oil was detected before and after tertiary recovery.
