“…At the close of the Triassic, the area was either subjected to tectonic uplift or eustatic sea-level lowering accompanied by a less arid climate and a greatly reduced carbonate platform. Non-depositional conditions affected the southern Arabian Gulf (Sadooni & Alsharhan 2004). Carbonate deposition shows increasing clastic content upsection with sandstones interbedded with marls and limestones.…”

Since the start of the twentieth century more than 550 commercially significant oil and gas fields have been discovered in the Middle East. Most of the fields have more than one pay zone and produce from shallow-water carbonates and clastics that range in age from Infracambrian to Oligo-Miocene. A providential juxtaposition of source-reservoir-seal, migration history and trapping mechanism has lead to the entrapment of hydrocarbons throughout the Phanerozoic strata of the Middle East. Each occurrence shares some characteristics but each also has unique features. The geographic occurrence of hydrocarbons in the region reflects the original facies variations across the depositional shelf and basin and the tectonic history of basement faults and halokinetic activity. The evaluation and integration of these critical variables, together with an appreciation of the maturation, migration history and trapping mechanisms, drives the search for new fields. The continued discovery of new fields proves that the region has not yielded all its treasure and stimulates future exploration. Although evidence for orogenic deformation is lacking in the Middle East, epeirogenic warping is common. The latter is attributed to the reactivation of basement faults, and evaporite structures and flow at depth. A prominent sedimentary and erosional break, locally marked by eroded Hercynian unconformities, followed an important Late Palaeozoic epeirogenic uplift. Similarly, Mesozoic sedimentary fill is broken by a major change in tectonic and depositional regimes, and numerous unconformities thought to be primarily controlled by high-frequency fluctuations in eustatic sea level and a low uniform rate of tectonic movement. Late Cretaceous and Tertiary events followed the collision and partial subduction of the east and southeastern margin of the Arabian Plate and involved vertical epeirogenic uplift of the resulting folded and thrusted gravity features. Vast areas of the Middle East Basin have yet to be extensively drilled. Although the long-lived stability of the shelf has influenced the development of the giant oil pools, and to some extent reduced the potential for stratigraphic traps, it has not eliminated the potential for smaller structures and the exploration for new oil and gas reserves. Future exploration is expected to focus on the discovery of smaller structures and subtle traps revealed by analysis of existing geological data and special seismic processing. Exploration will involve extensive regional and local geological–sedimentological studies, 3D or 4D seismic surveys and drilling progrmmes, and proposed better petroleum system model(s) for each basin (or sub-basin).

“…Both reservoirs were sealed by the anhydrite of the Adaiyah Formation. It produced 368API oil with sulphur content of 0.85% from the Liassic and 328API oil with 0.9% sulphur content from the Triassic (Sadooni & Alsharhan 2004).…”

“…1). The Triassic deposits form part of the hydrocarbon systems of Syria, Iraq and the Persian Gulf region, and have consequently been intensively studied (e.g., Powers et al, 1966;Druckman et al, 1975;Garfunkel and Derin, 1985;Alsharhan and Kendal, 1986;Bebeshev et al, 1988;Beydoun, 1991;Marcoux et al, 1993;Garfunkel, 1998;Robertson, 1998;Ziegler, 2001;Le-Nidre et al, 2003;Sadooni and Alsharhan, 2004). Outcrops in Egypt, Israel and Jordan reflect the epicontinental-marginal marine transitional belt of clastics and carbonates, superficially similar to Triassic lithofacies known from Europe.…”

“…The second stage followed in the Late Triassic to Middle Jurassic, when the width of the Neo-Tethys reached a maximum of 4000 km (Dercourt et al 1986). This phase of extensional tectonics subsequently produced localized troughs on the adjacent Arabian platform aligned in a remarkable arcuate pattern delineating two main trends: the western Taurus and an eastern Zagros trend (Sadooni and Alsharhan 2004).…”
