Abstarct: Sequence stratigraphy is the study of the generational relationship between sedimentary units which are limited by discontinuities and their equivalent levels, and used in the detection of hydrocarbon resources to determine the rock, reservoir rock, and caps rock. By studying the facies and the sedimentary environment and the spatial stratigraphy of the limited part of the region and studying the sequences in seismic sections, it is possible to find out more accurately and better than the expansion of the horizon reservoir and oil and gas reservoirs and optimal utilization of them achieved. Seismic data versus scattered well data, out crop and cores provide a systematic and continuous sampling of subsurface information and sequences. However, seismic data is less accurate than other data in the hierarchy. Therefore, where geometric geological interpretation is more reliable than seismic data where the vertical distance of the horizons is greater than the vertical seismic accuracy. For this purpose, after an accurate study of the litology and geology of the region, it was interpreted in a 3D seismic section. This is how the sequences were hand-picked and hand- crafted. Then, they were fitted with well data and well top, so the target horizon was detected and termination and seismic configurations were identified and by them, changes in sea level, including transgression and regression were investigated.
