Determination of hydrocarbon type in the lack of pressure gradients and the absence of sonic log is the main challenge in the zone of interest, In this paper, we used well logging relations between density and sonic in the wells which have sonic logs at the zone of interest to create synthetic sonic log, secondly by applying special petrophysical studies to help for estimation of hydrocarbon type. Two empirical equations were derived then these extracted empirical equations were applied to predict a sonic synthetic log for the two wells under investigation (unknown) which have no recorded sonic logs these are (B and C) wells. Crossplot technique was used to estimate the hydrocarbon type in the zone of interest using the synthetic sonic curve, original density curve, original neutron curve. The results of this study revealed that firstly the synthetic logs play a great role in solving of petrophysical and geological problems, secondly, the obtained synthetic sonic log from the derived empirical equations makes a sense with lithology and other logs (neutron and gamma) and it is recommended to be used in Badri field for the zone of interest level, thirdly, the synthetic sonic log, in corporation with the density and the neutron logs with the crossplots can help for estimation of fluid type. The final result that the most likely hydrocarbon type in well (B) is an oil zone while it is a gas zone signature in well (C).
