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 group. This formation is located in the Kazhdomi Formation of the slope. Kuhmond oil field is in the southeast of Bushehr and in the north and northwestern of Fars province. In this study, sedimentology studies, stratigraphy and sedimentary environment in Sarvak Formation were studied. Based on studies, 18 main Microfacies were diagnosed in the region that have been deposited in four facies belts including open Sea, dam, lagoon and tidal zones. According to studies, the sedimentary environment of Sarvak formation in Kohmond field was diagnosed as a ramp carbonate platform (Figure 1).

Highlights

Sarvak Formation is a thick carbonate stratigraphic unit that is part of Bangestan and is hidden in the Zagros region and southern margins of Neotitis
According to [1], from the Albian to Campanian, a sedimentary cycle of Kazhdumi, Sorga, Ilam, Sarvak formations can be identified that mentioned sets are called Bangestan group
Separations were carried out from the perspective of lithological rock units and at a later stage, identify and classify sedimentary facies was carried out accurately, in order to analyze facies and identify Lithology attributes, samples were studied and study the diagenetic processes of Laboratory study area was performed on 652 thin microscopic sections

Summary

Introduction

Sarvak Formation is a thick carbonate stratigraphic unit that is part of Bangestan and is hidden in the Zagros region and southern margins of Neotitis. According to [1], from the Albian to Campanian, a sedimentary cycle of Kazhdumi, Sorga, Ilam, Sarvak formations can be identified that mentioned sets are called Bangestan group. Jahrom and Sarvak formations form two heavy oil reservoirs in the oilfield of Kohmond
