“…stratal slices throughout the 3D classification data in the study area. These build-up geometries differ significantly from generally isolated build-ups, which were interpreted from well and outcrop studies of the Lower Cretaceous carbonate systems in Oman and UAE (Calavan et al, 1992;Witt and Gokdag, 1994;Fischer et al, 1997;Borgomano et al, 2002;van Buchem et al, 2002b;Droste and van Steenwinkel, 2004). Build-ups are heterogeneous and mapping them in 3D without using proportional slicing is a challenge.…”

“…A close relationship exists between the depositional facies of the carbonate build-ups and the reservoir properties of the time-equivalent Shu'aiba Formation in Oman and the UAE (Calavan et al, 1992;Fischer et al, 1997;Droste and van Steenwinkel, 2004). In this study, the classification has provided new information concerning the volume and connectivity of possible reservoir facies in the build-ups.…”

“…The overall regional setting during deposition of the Dariyan Formation was a shelf to shallow-basin complex, resulting in progradational mounds. A lowstand or shelf margin wedge of the equivalent Shu'aiba platform (Bab Sand Member, Fig.2) is observed in the UAE (Aldabal and Alsharhan, 1989;Fischer et al, 1997) but is probably thinly developed in the study area. An offshore development of calcareous shales with rudist debris occurs in this area and corresponds to the lower Dariyan Formation.…”

“…In the UAE, exploration and development wells indicate that reservoir quality in the Shu'aiba Formation is closely related to primary depositional facies, with the best quality encountered in prograding carbonates and/or carbonate build-ups (e.g. Calavan et al, 1992;Fischer et al, 1997;Borgomano et al, 2002;Droste and van Steenwinkel, 2004).…”

Interpretation of recently acquired 3D seismic data from the adjacent Sirri C and D oilfields in the SE Persian Gulf indicates that a 3D interpretation of seismic facies is crucial to resolve the internal stratal geometries of the Aptian Dariyan Formation. This carbonate formation passes southward into the Shu'aiba Formation, a prolific reservoir rock of similar facies in the UAE. Lack of exposures and limited cored intervals have forced reliance on the seismic data for evidence of the depositional environment and the internal architecture of potential reservoir rocks. The progradational nature of the Dariyan Formation and the occurrence of carbonate build‐ups within it make this stratal geometry complex. The complex internal heterogeneity of the build‐ups and presence of seismic noise make mapping of the build‐ups in 3D space using conventional seismic interpretation tools difficult, despite the availability of high‐quality 3D seismic data covering the area. The high quality seismic and limited well data from this field is one of the few datasets of this kind presented in the literature. A procedure for the hierarchical multi‐attribute analysis of seismic facies using Paradigm's Seis Facies software is used in this study to provide a 3D interpretation of the stratal patterns. Principal component analysis reduces the noise and redundant data by representing the main data variances as a few vector components in a transformed coordinate system. Cluster analysis is performed using those components which have the greatest contribution to the maximum spread of the data variability. Six seismic attribute volumes are used in this study and the result is a single 3D classified volume. Important new information obtained from within the Dariyan Formation gives new insights into its stratigraphic distribution and internal variability. This method of processing seismic data is a step towards exploring for subtle stratigraphic traps in the study area, and may help to identify exploration targets.

“…As in eastern Fars, the creation of an intrashelf has been reported from the Bab basin to the southern Persian Gulf. This latter basin was surrounded by a shallow ramp that likely contained narrow channels (Murris, 1980;Fischer et al, 1995;Grabowski and Norton, 1995;Hooper et al, 1995). The limited communication of the Aptian intrashelf basins with the adjacent Neo-Tethys Ocean established suitable conditions for organic-rich sediment deposition (Van Buchem et al, 2010a).…”

The Lower Cretaceous of the Arabian Platform is renowned for the development of intrashelf basins. The study area is located in eastern Fars Province on the northeast Arabian plate and has experienced this environmental condition. The present study investigated two surface sections (Genau and Anguru) of the Dariyan Formation and compared the results with three neighboring wells in eastern Fars (eastern Zagros Fold Belt) in southern Iran to determine the development of rudist-bearing carbonates and intrashelf basin sediments. The Dariyan Formation was deposited in the Aptian as shallow-to-deep water carbonate facies. Lagoon, rudist banks/barriers, and open marine/basinal facies and six microfacies types have been distinguished. In the Genau section, the upper formation contains shallow rudistid limestone separated from the orbitolinid limestone of the lower formation by a deep pelagic unit. The pelagic sets disappear toward the Anguru section, but the rudistid unit remains. Abrupt changes were observed from shallow rudist facies to deep planktonic foraminifer facies. Comparison of the surface and subsurface sections (wells) suggests an intrashelf carbonate depositional model for the Dariyan Formation in the eastern Fars area. The term "Genau intrashelf " is proposed for this intrashelf basin surrounded by a shallow ramp. This intrashelf appears to be a northern subbasin of the Bab basin of the southern Persian Gulf. Extension of the Genau intrashelf subbasin and development of rudists around the margins of this intrashelf can be defined by tracing changes in the lateral facies of the Dariyan Formation.
