This paper sheds light on imaging of subsurface structure of South East Ghara in South Gulf of Suez based mainly on the analysis of aeromagnetic and seismic data. Since, there are several problems in South East Ghara regard to the hydrocarbon exploration. For example, the facies change in the same reservoir along the study area, which refers to the same age, complex compositions and their impact on the presence of oil gathering, and other reasons, which led to study and image the structure of the area.
The analysis strategy included, firstly magnetic based basement tectonic analysis to illustrate the detailed structures of basement complex. Secondly magnetic and seismic based depth structural mapping. The results show the basement surface configuration as well as (Nubia, Matulla, Nukhul, Rudeis, Kareem, Belayim, South Gharib and Zeit); most of them are dissected with nine clysmic normal faults. The basement tectonics analysis indicated that the area affected with dip-slip faults that considered the main cause of forming of the tilted faulted blocks in the study area and have trend NNW-SSE to NW-SE. One of these tilted faulted block forms the horst structure trend which separates between the Ghara basin and Eastern basin. The ENE-WSW to NE-SW trending faults are interpreted as probable strike-slip faults that represent the younger faults. The depth mapping based on interpretation of seismic data for three horizons (basement complex, Nubia, Matulla) show that the interpreted depth values ranged from 16500, 16400, 14400 ft subsea in its deepest point located in the northwest, and 4700, 4600, 4500 ft subsea in its shallowest point in the southeast of the study area, respectively. Based on the information extracted from drilled wells and the structure analysis, the study suggests presence two promising localities (leads) and three prospects in Nubia and Matulla formations.
