Abstract
Sarvak formation is one of the important hydrocarbon reservoirs in the Zagros Basin that is one of the mid-Cretaceous carbonate units in Bangestan. This formation is located in the Kazhdomi Formation with the same slope. Geology, Kohmond field is located in the southeast of Bushehr and north and northwest of the Fars province. In this project, the geology, the tank and Petrophysics features were studied in the field with sedimentology; stratigraphy, Petrophysics, sedimentary environments and reservoir data analysis. According to studies, sedimentary environment of Sarvak in the Kohmond field is diagnosed as a ramp carbonate platform. Sarvak reservoir modeling in this field was done by using Petrelli software. The results indicate parts with high porosity, which are focused more in central and southeastern parts of the field and can contain large amounts of oil.
Highlights
One of the most important petroleum basins in the Middle East is Zagros Basin that the largest of the Iran reservoirs is located in the geological zone of the Zagros and Basin in the Persian Gulf (1980 murris)

The evidences were obtained based on heavy oil in Asmari Jahrum formation and Bangestan group “Kohmond”
Summary
One of the most important petroleum basins in the Middle East is Zagros Basin that the largest of the Iran reservoirs is located in the geological zone of the Zagros and Basin in the Persian Gulf (1980 murris). The evidences were obtained based on heavy oil in Asmari Jahrum formation and Bangestan group “Kohmond”. Because the depth of these formations was low in the Monde field 250 - 1500 m and the reservoir has been considerable dimensions (12.5 × 72.5 km), the reservoir of Sarvak in this field is considered as the first heavy oil exploration field. Sarvak formation is a thick carbonate stratigraphic unit that is part of Bangestan group; it is deposited in the Zagros region, and the southern fringe of Neotitis. Aveili ing to James and Wynd’s report in 1965 from the Albian to Campanian, a sedimentary cycle of Kazhdumi formations, Sorga, Ilam, Sarvak can be identified in the Zagros that set list is called the Bangestan group. Jahrum and Sarvak formations are two heavy oil reservoirs in the oilfield of Kohmond (Figure 1)
