Transient heat flow model in the Petromod 7.1 software was chosen to model the thermal histories of the individual wells (1, 2, 3, 4 and 5). They were selected on the basis of suitability for thermal modeling using Petromod 7.1. The maturity modeling of the preserved stratigraphy calibrated against vitrinite reflectance Ro and Tmax demand the palaeo-heat fluxes ranging from 56.6 to 66.75 mW m-2. The results indicated that the measured maturity data in five wells were in agreement with a transient heat flow model. The modeled results indicated a good match of the simulated maturity data (vitrinite reflectance Ro and Tmax) with the measured data in all wells. The result also showed that the maximum paleo-temperatures were attained by the three source beds (Wen Chang, En Ping and Zhu Hai Formations respectively from bottom to top) in Bai Yun depression and Pan Yun Low Uplift during Early Miocene. The Eocene source rocks started to expel hydrocarbons during Early Miocene to Present.]]>Allen, P.A. and J.R. Allen,1990pp: 282-283pp: 282-283Briais, A., P. Patriat and P.
