Summary The Precambrian tectonic setting is important to understand the oldest petroleum systems of Oman, including the distribution of our main source rocks in the Huqf Supergroup, the reservoirs of the Nafun, Ara, Nimr and Haima plays, the basin subsidence history and diagenesis, and the early deformation history and trap creation. Recent multidisciplinary studies, including sedimentology, heavy minerals and detrital zircon geochronology, support that Oman formed at the western margin of the Indian Shield (Eastern Gondwana) during the Neoproterozoic (Tonian), and that it only collided with the Arabian-Nubian Shield (Western Gondwana) in the Early Cambrian (~525 Ma ago). This resulted in the formation of the Western Deformation Front, which marks the final suture between East and West Gondwana. Oman stayed as part of Arabia after Permian-Jurassic Gondwana break-up. These tectonic changes are tracked by depositional evolution, tectonic/magmatic events as seen by detrital zircon geochronology, and sediment distribution patterns. Our results entail a significant update to our present tectonic evolution and plate reconstruction models of eastern Arabia, and to our understanding of the early petroleum systems of Oman.

Summary Based on recent multidisciplinary studies of the Precambrian succession of Oman, both in PDO cores and in outcrops, a new correlation from type sections in outcrops to the subsurface is proposed. The results have implications for source and reservoir rock distribution, stratigraphy, and Precambrian tectonic setting and evolution of Oman. The type Precambrian Nafun Group sections are found in the Huqf outcrops of central Oman, and represent a proximal, continental to shallow marine sequence up to ~2000 m thick. The succession studied in the subsurface is ~800 m thick and dominated by deeper water, basinal deposits with numerous source rock intervals and poor potential as conventional reservoirs, more alike the Precambrian succession exposed in north Oman. Reservoir rocks are proven in shallow water carbonate deposits of the Khufai and Buah Formations, and are possible in clastic deposits of the Masirah Bay Formation. The best source rocks are found in basinal deposits of the Masirah Bay, Khufai and Buah Formations, and were deposited during transgressive system tracks. Paleofacies maps and regional distribution support Ediacaran deposition controlled by regional thermal subsidence along a passive margin on the eastern side of the Mozambique Ocean.

Abstract In the past decade, Petroleum Development Oman (PDO) has been actively drilling deep tight gas wells targeting structural four way dip closures in the Miqrat Formation (middle Cambrian). The Miqrat Formation was widely deposited in an arid to semi-arid continental setting in alluvial and playa/sabkha environments. The wide distribution of the Miqrat formation and the lack of high resolution seismic together with unavailability of dense well information imposed various challenges in developing accurate subsurface depositional models. The play depositional model was constructed as simplistic as possible assuming a wide-spread playa which tends to be sandy in the south and muddier toward the north. In addition, the previous models were forcing the correlations to fit the entire reservoir subdivisions (Upper, Middle & Lower) to be present within the play domain. This served the regional understanding for prospect identification. However, when zooming into field-scale areas it becomes obvious that the depositional model needs further refining to understand the well data and the flow behaviors in various domains. Recently, with the arrival of high resolution wide azimuth seismic data and the availability of denser well penetrations, a relook was applied to the previous depositional model by integrating various multidisciplinary inputs including: well log evaluations, seismic inversion for reservoir characterization, well test results and pressure measurements. The data integration revealed that the Miqart reservoir properties and thickness are highly influenced by the paleo structural elevation variations and the accommodation space post the Angudan unconformity (poor properties close to the highs). These variations resulted in lateral change to thinner/poorer units or onlaps on dominant highs, and the existence of capillary trapping ( Figure 1 ). As a result, the tighter and thinner facies retained significant amount of water which did not succeed to get flushed by late gas charge due to capillary barriers. Therefore, wells which are drilled in good reservoir properties in a structurally down dip position show better gas saturation with high gas and low water production rates in comparison to the wells which are drilled up dip in poor properties within the same traps ( Figure 2 ).

Elemental chemostratigraphy is employed on outcrop and well sections in order to produce a regional surface to subsurface correlation framework of the late Neoproterozoic and early Cambrian sediments in Oman. Samples have been analysed using ICP techniques, with high-resolution data acquired for 48 elements. The key elements employed to produce the chemostratigraphic framework are Si, Al, Ca, Mg, Ti, Zr, Y, Th, the rare earth elements, Cr, Mo and U. The relative abundance of these elements are interpreted be influenced by changes in lithology, detrital heavy minerals and redox-sensitive authigenic minerals that themselves are interpreted to reflect temporal variations in environment, weathering and sediment provenance. Based on marked variations in the key elements and derived element ratios, the study interval is divided into six chemostratigraphic sequences and six higher-resolution chemostratigraphic packages. The chemostratigraphic zones can be correlated with confidence from the outcrop to subsurface and, in conjunction with other disciplines, is being employed to refine the lithostratigraphy of the Nafun and Ara Groups in the subsurface of south Oman.

Sometimes the best quality conventional source rock is not the most prospective unconventional resource. By understanding how hydrocarbons are expelled from organic-rich intervals, it is apparent that poorer quality source horizons are more likely to retain hydrocarbons in place. Rather than better quality source rocks which expel a large quantity of hydrocarbons, which then migrate to conventional traps. Therefore, by identifying stratigraphic horizons of varying source quality in the Silurian of the Middle East prospective horizons which have retained some charge can be identified. By understanding the plate scale structural architecture, areas where these source rocks subcrop low-angle unconformities covered by sealing facies can highlighted. The potential for sealing facies to occur above the unconformity, limits the expulsion and migration of hydrocarbons from the source rocks. This may be further enhanced by the inability of poorer quality source rocks to expel hydrocarbons. This shows that a number of Montney-esque play types within the Silurian of the Middle East may exist. Most notably where the Silurian Qusaiba Member subcrops the Unazyah Formation and where particular parts of the Silurian are in unconformable contact with sealing facies of the Unazyah.

The Neoproterozoic glacial deposits outcrop throughout Death Valley area in California. The outcrop in Saratoga Hills show a thick succession of the glacial stratigraphy showing significant variation in bed thickness, and clast-compositions that are used to prove the great variation of the flows even within a short lateral distance. This sequence shows a gradual change from glacio-proximal to glacio-distal tracts that are interpreted as the first documented trough mouth fan of the Neoproterozoic glaciation.
