| Abstract | Fang basin is the oldest oilfield in Thailand. It consists of three sub-basins, and namely, northern, central and southern Fang. Although the field has been produced for many years, no detailed study on basin modeling and petroleum system has even been done. The aim of this thesis is to carry out a ID basin modeling for Fang basin by using Petromod software. The ID basin modeling included deposition analysis, compaction analysis, heat flow analysis and maturity analysis and petroleum generation. Data from 9 wells were selected, including temperature from DST, Ro%, and Rock-Eval pyrolysis data. To prepare the input file for basin modeling the depths of formation were taken from 2D seismic section, the depths were then corrected based on comparison with the drilling data. In addition to depth, the ages of formations were also input for reconstruction of burial history. Burnham and Sweeny (1990) thermal calibration model (EasyRo%) was used and calibrated with the measured Ro%. The results of heat flow analysis showed that the paleoheat flow has increased during the rifting period from 30 t05 Ma and decreased during the post-rifting period from 5 to 0 Ma. The present day heat flow varies from 44 to. 120 mW/m, the temperature gradient varies from 0.03 to 0.07 °C/m. The petroleum generation was calculated using the kinetic model by Burnham and Sweeny (1989) (type III) and Tegeelar (1994) (type I). There is only 1 well shows oil generation and expulsion from source rock. The source rock is lacustrine shale which has the kerogen type I in Mae Sod formation (1372-1497 m.). The hydrocarbon potential is 119 mgHC/gTOC. The oil expulsion mass was calculated as 0.0148 Mtons or 14.8 Mtons/km² (equivalent to is 0.107 MMbbl). The time of oil expelled is 1 Ma. The basin modeling was successfully for the northern and central sub-basins of the Fang basin. Although the modeling work is considered preliminary due to limited data that were available to the study the methodology can be well applied for mote detailed modeling works in the future. It is also recommended that the basin modeling work can be performed for the whole basin |
