“…Interpretation: The ooilitic ironstones are present in non-marine sandstones, mainly in deltaic systems [34]- [36]. These sediments are dominant in Delta fronts, particularly in warm, tropical, river-dominated deltas (Morad, 2010).…”

Dariyan (Shuaiba) Formation is one of the main reservoir units in the Persian Gulf and South Western Iran. The microfacies and depositional environment of this formation is been investigated in the current study and influencing factors in reservoir characteristics have been discussed for Dariyan reservoir in the Soroush oil field. Facies analysis conducted on core and cutting samples indicated that Dariyan Formation is mainly deposited on a carbonate ramp setting with a shallow intra shelf basin. In addition, it has been demonstrated that facies changes reflect the main controls of the tectonic and climate (sea level fluctuations) during the deposition of these sediments. To determine the reservoir unites in this formation, 5 electrofacies were determined by neural network method that it is using different petrophysical logs (i.e. GR, PHIE and SWE). Using rock typing as the best way to establish an association between the various collected data (e.g. logs and cores) and geological descriptions 4 hydraulic flow units or rock types, determined on the basis of the Flow Zone Indicator (FZI) method in the Dariyan Formation of the Soroush field. Establishing a correlation between microfacies and rock types, the carbonate zones with moderate to good reservoir properties and also the intervals with the highest reservoir quality were determined.

“…High sand input of red-stained siliciclastics may indicate proximity to the shore line settings. Extensive horizontal bioturbation, wavy bedded, grain-rich nature, and erosional contacts point to the sedimentation in a subaqueous bar in a deltaic system [32] [35] [36].…”

“…At a major scale, bounding surfaces and diagenetic processes are key controlling parameters; diagenesis exerts a strong control on the quality of most clastic reservoirs (Morad et al, 2010). The develop ment of early-clay films around grains (Seemann, 1982) as observed in Fig.…”

“…The develop ment of early-clay films around grains (Seemann, 1982) as observed in Fig. 11, prevents the development of quartz cementation thereby pref erentially preserving porosity of the aeolian sandstones (Taylor et al, 2004;Morad et al, 2010). Aeolian bounding surfaces form important permeability barriers for fluid flow in aeolian successions (Taggart et al, 2010).…”

“…(Dutton, 2008;Taylor, 1990;Wang et al, 2016;Xiong et al, 2016). Earlyprecipitation of pore-filling carbonates could increase the pressure-resistance of reservoir sandstones and provide a chance for subsequent dissolution (Chi et al, 2003;Morad et al, 2010), whereas late-precipitation of carbonate cements filling residual pores could reduce the final porosity. Therefore, the timing of precipitation, dissolution and distribution of carbonate cements exert significant effect on reservoir quality.…”
