ABSTRACT: Subsurface Fault Prediction in the Central Gulf of Suez Rift: Using a Fault Model Derived from the Subsurface and Outcrop Data
The relationships between the structural setting of surface and subsurface in the Belayim area, western Sinai, is equivocal. The quality of seismic data is generally poor due to the presence of thick evaporites and the ensuind noises. Faults observed in outcrop are difficult to relate to seismically detected ones. The latter seem to intersect and/or bifurcate at random from major coastal faults. Detailed surface and subsurface geologic investigation with data obtained from onshore and offshore wells drilled for oil resulted in the structural model presented here. The coastal bounding listric Clysmic faults splitinto branches that enclose spindle and/or triangular shaped, northeast titled blocks. This branching provided communication between the onshore and offshore Belayim oilfields. Moreover, this splitting of faults to form spindle-shaped blocks seems to be common feature in the central Gulf of Suez province (e.g. Belayim, Rudeis-Sidri and Feiran oilfields). The structural model of the Belayim oilfields titled blocks is closely similar to the surface Feiran titled block to the east of the study area.
