The Arab Formation in OAD is a major regressive unit which was deposited on a broad carbonate platform and prograded eastwards into an open marine shelf environment. Later oil remigrated and was trapped in anticlines that began to form in Early Cretaceous time. Make available the basic areal geology as mapped by Aramco and the US.

D C B A consisting of a lower unit of bioclastic lime mudstone or wackestone with normal marine fossils a middle grainstone unit of clean washed calcarenite composed off rounded skeletal particles and an upper thin tidal-flat dolomite mudstone that grades within a few feet to thick nearly pure supratidal anhydrite Alsharhan and Kendall 1986.
Geology of the United Arab Emirates. The Arab formation is represented by four shoaling-upward cycle s from bottom to top. These shales and sandstones thin northeastward and are replaced in the subsurface by shallow water limestone known as Khail and Gulailah formations.
A return to lower salinity and shallow marine conditions in the Middle Eocene deposited the nummulitic carbonates of the Dammam Formation as well as dolomite and subordinate shales. In general terms the D Member of the Arab Formation was deposited during the Upper Jurassic in the shallow Tethys Sea on a broad relatively stable shelf or platform. The other is the Middle Cretaceous ShilaifKhatiyah Formation which feeds both Mishrif and Simsima reservoirs.
