The occurrence of hydrocarbons is closely linked to the elements of petroleum system history of the Sitra 8 oilfields, which has created multiple reservoir and seal combinations. Sitra concessions occupy the northwestern part of the Abu Gharadig Basin and extends between latitudes 29_450 and 30_050N and longitudes 27_300 and 28_100E. The comprehensive integration of the geo-related data and the interpretation of the seismic data in time domain and depth and sealing mechanisms explain the occurrence of hydrocarbons in some certain reservoirs during cretaceous age and. Detailed seismic data interpretation was performed for the target units Sitra 8 oilfields in time domain and converted to depth domain. Sitra 8 Field is a three-way dip closure bounded by NW–SE faults.
