Abstract
Sidki field is one of the B-trend oil fields located in the central southern part of the Gulf of Suez, Egypt. The Gulf of Suez acquired its importance from having hydrocarbon resources. It is described as an elongated depression (400 km long) separating central Sinai Peninsula from Africa. It also represents one of the most intensively faulted areas of Egypt, which is dominated by major normal faults trending NW-SE and tilted fault blocks with sedimentary fill up to 6 km thick. The quality of the seismic records in the southern part of the Gulf of Suez is generally poor due to the presence of thick evaporitic sequence in the upper Miocene. Hence, the using of coherence seismic attribute will be an effective tool in visualizing the trends of faults, which are not visible in seismic amplitude information. The main objective of this study is to identify and delineate the possible subsurface structures of the area. The methodology combined conventional interpretation of 3D seismic data of the study area and then analyzing the coherence seismic attributes of the same 3D seismic dataset to enhance the fault interpretation. The conventional interpretation of the 3D seismic data reveals four normal faults having NW-SE trend, and other three new faults interpreted after applying the technique of coherence attribute analysis. These faults are also trending NW-SE and dipping to NE.
