The goal of this study is to use petrographic and other sedimentary features to interpret depositional environment of Faraghan Formation (Lower Permian) in one of the wells in Golshan Field. Golshan Gas Field is located at about 180 km South East of Bushehr between South Pars and North Pars and Ferdowsi Fields. In this study, 130 thin sections of cuttings have been studied, and 8 petrofacies and 3 microfacies and 2 hybrid arenite fasies were identified in the well. Textural maturity of sediments, such as well- sorted and rounded quartz grains, show that the Faraghan Formation was deposited in coastal and shallow marine environments. The identified Facies has been deposited in sabkha, estuarine, foreshore, shoreface and offshore subenvironments.
