Soroosh field
The Soroosh field is located about 80 km west of Kharg Island, in which oil is mainly produced from the Albian Burgan Formation. This formation shows various thicknesses in different parts of the Arabian plate. Its maximum thickness is about 390 m in the east of Kuwait. The studied units are equivalent to lower part of the Kazhdumi Formation in northwest of the Persian Gulf and upper part of Burgan in northern Kuwait. The studied formation (known as Burgan Formation here) is mainly composed of sandstone and shale. The organic matter in the shaley facies is considered terrestrial in origin and related to a coaly environment. Results from rock-eval studies have shown that the shale facies are not reach to the onset of oil generation. The bitumen-bearing facies is generally confined in the Dezful Embayment by a network of basement faults and partly along the Oman fault, south of Bandar Abbas.

The Burgan Formation occurs on top of the Dariyan (Shuaiba) Formation in the studied area, where is overlain by Dair Formation. Al-Fares et al., 1998 reported the existence of a major hiatus on tap of the Dariyan Formation (Figure 2). Studied formation (Burgan) in northwest of Persian Gulf is a distal equivalent of plant-bearing deltaic sandstones and shales of the Burgan Formation in Kuwait and the NahrUmr Formation in Iraq. In the studied field the Burgan Formation is placed on top of upper Shuaibaclastics. It has been well studied in oil fields of North West of the Persian Gulf, where is informally divided into two parts (Burgan A and B). The Burgan Ain upper part of the formation is dominated by shale and consolidated sandstone. The Burgan B (the reservoir unit) in the lower part of the formation is dominated by fluvial sandstone facies.
