Abstract

The study area is located between Latitudes 27º 37 50″ and 27º 53′ 51″ N and Longitude 33º 28′ 51″ and 33º 45′ E. It comprises a part of the southern Gulf of Suez rift basin, which represents the most prolific and prospective oil province in Egypt.
The main target of this study is to achieve the regional tectonic framework including mapping of the different basement tectonic trends associated with uplifted tilted basement fault blocks of possible hydrocarbon potential within the study area.
In order to achieve the previous goal, the following steps and procedures were done:
A complete review of the Gulf of Suez (G.O.S.) geology and stratigraphy from published materials was done which revealed that the study area has both Miocene (Nukhul, Rudeis, Kareem and Belayim sand), pre-Miocene (Nubia sandstone and Matulla) reservoirs and also Fractured basement reservoirs. Moreover, it also revealed that the source rocks within the study area are represented by Cretaceous and Eocene rocks: Duwi, Esna shale and Thebes formations.
The seal rocks in the study area are represented by S. Gharib and Lower Rudeis shaly formations.
As far as the tectonic setting of the studied area is concerned, it can be explained by the Dog-leg rift model with the clysmic (NW) tectonic fault system exhibiting some deviations from north either into N. oblique or NW. oblique. Cross-faults of different orders and orientations are present in the study area that limits the existing oil fields from north and south.
Qualitative Processing of aeromagnetic data involved construction of an R.T.P magnetic map, isolation of residual and regional magnetic anomalies using band pass filtering, as well as an Second Vertical Derivative operator that has been used to produce a residual magnetic map that best approximates the uplifted tilted basement fault blocks; structural traps; associated with possible hydrocarbon leads.
Quantitative Processing of aeromagnetic data were used to determined the depth to the basement complex by the most advanced techniques as Werner Deconvolution, Spectral Analysis Method and 3-D Analytic Signal Method.
Also Four (4) R.T.P. magnetic profiles were modeled to quantify the basement shape, depth and configuration.
As a result of the previous techniques and through both qualitative and quantitative interpretations, a Basement Tectonic Map was constructed. This map shows eight (8) tectonic trends of either NW, N.oblique or NW oblique tectonic trends that cut across the studied area. Some of these tectonic trends are associated with intermediate rhombic blocks The basement tectonic map shows several structural magnetic leads that are not drilled within the studied area either of type I (Miocene and pre-Miocene potential) or type II (Miocene) potential only.
