 Five palynozones were identified into the Bahariya section and were helpful in better understanding the reservoir geometry of the main productive zone into Palynozone Two.

The integration of palynological, sedimentological, seismic and E-Log data provided valuable paleoenviroment information. It indicated that the Bahariya sedimentary section was deposited in relatively deepening upward environment where it ranges from more terrestrial in the lower part of Lower Bahariya, to fluvial dominated deltas which has been largely controlled by tidal current, and to prograded shallow marine to shallow marine for the Upper Bahariya.

Sequence and parasequence boundaries are determined with the help of palynology, and this was found to be supported on the inverted seismic section, while it was not clear on conventional seismic data.
