Abstract
In this study, it is aimed to model the seismic reflection responses of structural and stratigraphic origin channel, anticlinal, normal fault, granite wash and bioherm type hydrocarbon traps, which are important in terms of hydrocarbon exploration, in a shot domain and to obtain stacking/migration sections. The calculation of the model data was carried out with the two-dimensional acoustic finite difference method due to its practicality of use, economic computational cost advantage and the possibility and convenience of selecting different trap models on arbitrary. For the trap models, artificial seismic reflection data of the shot domain were calculated and zero-offset sections were obtained by applying appropriate data processing techniques to these data. Thus, the effects of the geometry and discontinuities of the trap structure on the reflection waves were examined, the extent to which data processing applications contributed to the noise problems were tested, the initial geological model and zero-offset sections were compared, and the causes of the problems were discussed. In particular, scattering wave interference was found to adversely affect the choice of velocity in velocity analysis. In solving these problems, the advantages and disadvantages of pre-stack and post-stack migration processes were evaluated. Consequently, the modeling of pre-stack shot data instead of post-stack shot data, especially before a hydrocarbon exploration field study in complex geological environments, will increase the consistency of seismic section interpretations with the real geological structure and thus the reliability of the interpretation in the development of data processing workflows containing the most appropriate processing parameters.
