- •
Sequence stratigraphy and depositional pattern of Es4s were documented and discussed.
- •
Sedimentary facies elaborated and described with accordance of characteristic petrological and mineralogical features.
- •
Clastic beach-bar facies (equal or more than 3 m) mainly developed in LST, have good potential towards reservoir.
- •
Carbonate cementation in short high frequency sedimentary cycles and clays affect the reservoir quality significantly.
- •
Interbeds of mud and sand show depositional while cementation and compaction are main causes of diagenetic heterogeneity.
