“…It also acts as a frame builder (encruster) in higher energy settings on the platform margin. Similar Cretaceous occurrences have been noted elsewhere by Frost et al (1983) and Maurin et al (1985). The oyster-like Chondrodonta has been reported in platform margin to back reef environments for the Lower Cretaceous (Jacka & Brand, 1977;Scott, 1979;Minero et al, 1983;.…”

A Lower Cretaceous carbonate platform depositional system with a rimmed margin and an adjacent oversteepened slope was analysed in order to determine its depositional architecture and major depositional controls. The platform is made up of coral, rudist, orbitolinid and algal limestones and, in a 12‐km dip transect, there is a gradation from lagoon to platform margin, slope and basin environments, each characterized by distinctive sedimentological features and facies associations. The rimmed platform is an aggradational system developed during approximately 4·2 million years of fluctuating relative sea‐level rise, and it is bounded by unconformities at its base and top. Internal cyclicity in the construction of the system is evident, mainly in platform interior and slope settings. The seven recognized sequences average 0·6 million years in duration and are related to minor relative sea‐level changes. Carbonate deposition occurred in shallow‐ and deep‐water settings during periods of high relative sea level. Reduced rates of sea‐level rise led to the development of shallowing upward sequences and, eventually, to the exposure of the shallowest parts of the platform during relative sea‐level falls. During low relative sea level, erosion surfaces developed on the slope, and gravitational resedimentation occurred at the toe of slope. Basinwards, resedimented units pinch out over distances of a few hundred metres. Active faults controlled sedimentation at the platform margin, promoting the development of steep slopes (up to 35°) and preventing progradation of the shallow‐water platform, despite high sediment production rates. The development of sequences is interpreted to be related to tectonic activity.

“…The Shu'aiba Formation in the Arabian Peninsula is an exceptionally well-studied interval (Frost et al 1983;Litsey et al 1983;Harris et al 1984;Alsharhan 1985Alsharhan , 1987Aldabal & Alsharhan 1989;Scott 1990;Alsharhan & Kendall 1991;Hamdan & Alsharhan 1991;Abou-Choucha & Ennadi 1993;Azer & Toland 1993;Boichard et al 1995;Hughes 2000Hughes , 2005Sharland et al 2001;Yose et al 2006;, although controversy still remains about its age, stratigraphy, depositional environments and diagenesis.

Reservoir quality prediction has historically been the 'holy grail' of reservoir geologists, yet few have succeeded at achieving this in a quantitative fashion. This study presents a new approach to pre-drill reservoir quality prediction that involves the integration of a variety of modelling techniques to understand, quantify and predict the geological processes that control reservoir quality. Since the initial reservoir quality framework is established at the time of deposition by a variety of depositional controls, this approach uses numerical process models to predict initial reservoir quality; results from these depositional models are then modified via a series of process modelling technologies to quantify and predict post-depositional modifications that have significantly affected reservoir quality in the interval of interest. This approach is illustrated using an example from the Early Cretaceous Shu'aiba Formation in eastern Saudi Arabia, where depositional facies, diagenesis and resulting reservoir quality are predicted and tested against well and seismic data, with generally positive results. Model-predicted sediment thicknesses match thicknesses measured in wells to within +0.5%; depositional facies and diagenetic trends seen in key wells from the Shaybah field matched model-predicted facies and diagenesis; and model-predicted porosity matched observed porosity within +1.8 porosity units.

“…1) took place under basinal conditions. On the contrary, most onshore fields in Abu Dhabi (HARRIS, HAY and TWOMBLEY, 1968;FROST, BLIEFNICK and HARRIS, 1983), Qatar and Oman (WITT and GÖKDAG, 1995) are in shallow-water carbonate platform settings. But the majority of the existing interpretations of stratigraphic relationships between onshore and offshore, formations are incorrect.…”

An integrated case study of field "A" in offshore Abu Dhabi found that the stratigraphic framework for the uppermost part of the so-called "Thamama Group" required revision. Detailed sedimentological work permitted a subdivision of the succession into lithostratigraphic units (more accurately "allostratigraphic units") and the fossil content permitted their allocation to standard age-related units ranging from Late Barremian through Middle Aptian times. Additional work focused on the so-called "Shu'aiba Formation" and resulted in a new and comprehensive interpretation on a regional scale which differs from published interpretations based on onshore studies in Abu Dhabi, Qatar, and Oman.
