Short summary
In this biostratigraphic study of the Middle Miocene–Early Pliocene sequence in the El-Wastani gas field, Egypt, microscopic inspection of the samples enabled the designation of six foraminiferal zones and subzones. Seven stratigraphic sequences have been identified based on the foraminiferal and calcareous nannofossil diversity. Depositional sequences and sequence boundaries are recognized by the integration between the seismic data, biostratigraphic zones, and wireline logs (gamma rays).
