Asl and Hawara sequences (S30) are among the important Miocene reservoirs in the Gulf of Suez. Gupco has currently produced lot amount of oil from this reservoir. This sequence (S30) represents a model for developing a prolific reservoir in tectonically active basin. Facies analysis produced from studying cores and ditch cuttings from different wells is done including sedimentological, petrological, and paleoecological interpretations.

The study indicated that the clastic supply originally was derived from mountainous ranges bordering the western side of the Gulf of Suez. The tectonic movements as well as the relative stand of sea level played an important role in the sand distribution, where series of unconformities appeared from the uplifting blocks leaded to produce accommodation zones for reservoir sand accumulated. A depositional environment model for such S30 reservoir is constructed.

Implementing the above-mentioned factors helped in mapping reservoir Asl and Hawara reservoir sands and enhance future exploration activities.
