Sequence Stratigraphy, Seismic Facies and Prospectivity of West El Burullus (WEB) Filed, Offshore Nile Delta, Egypt

This study presents an integrated seismic sequence stratigraphy and biostratigraphic analysis of the Pliocene Kafr El Sheikh (KESH) Formation in the West El Burullus (WEB) concession, offshore Nile Delta. The research focuses on characterizing the depositional architecture of turbidite channel systems and their implications for hydrocarbon exploration. By identifying the major NN13 nannofossil sequence boundary through seismic interpretation and well calibration, the study reconstructs the paleo-topography and depositional environment of the WEB channel system. The methodology combines seismic, stratigraphy, and biostratigraphy with seismic attribute to revealing the complex history of reservoir development and distribution.

The applied workflow demonstrates significant value in reservoir characterization and prospect identification. Key applications include: (1) distinguishing between channel axis and levee facies through seismic attribute analysis (coherence, spectral decomposition), (2) mapping sand distribution patterns via amplitude extraction, and (3) identifying multiple phases of channel activity. The biostratigraphic calibration from WEB NE, WEB NE st, and WEB NW wells confirmed the NN13 age of the main sequence boundary and helped differentiate channel generations. These techniques enabled the identification of undrilled compartments and potential stratigraphic traps along channel margins.
