| Abstract | The hydrocarbon exploration in the Khorat Plateau, North Eastern Thailand has been started since 1971. The exploration activities are increasing more and more. The basin modeling is necessary to help assessing HC potential. The 10 basin model has been done by using Petro mod software of Schlumberger. The sensitivity analysis has performed in order to help in having more confidence level of the results. The sensitivity was done by changing the input parameters such as formation age, erosion thickness, heat flow, kinetics, and kerogen type. The model is calibrated with measured vitrinite reflectance (Ro). The model which has a good fitting of measured Ro and calculated Ro is then used for further simulation to assess the HC generation. The HC prediction was done using the kinetic models ofTissot in Waples (1992) and Burnham (1989). The geopressure is one of the important factors that has to take into account for the HC exploration in the Khorat Plateau as various pore pressure were encountered while drilling the exploration and production wells in the area. The geopressure analysis was successfully developed using Eaton's method (Eaton, 1975) to determine the geopressure of the study well. The normal compacted trend (NCT) of density is constructed from density logging data as this NCT is needed for the calculation by using Eaton's equation. The NCT is constructed to observe the change of density through the whole depth interval. The NCT of density and sonic logging data give an equation Pb= 0.1021n (z) + 1.942, the NCT of .T give and equation v = (In (z)-3.36)/0.00071 respectively. The Eaton exponent (E) and effective stress coefficient (n) were formed based on the matching with DST pressure data. As the determination results obtained E = 1.76 and n = 0.9.With the E = 1.76 and n = 0.9, the geopressure profile was calculated for the BHX well location. It was found that, the potential geopressure zone was in the depth of 1,450m to 2,200m. The magnitude of the geopressure is varying for each particular depth and the most significant magnitude is approximately at depth 1,800m |
