in order to determine the physico-chemical characteristics of oils from upper sarvak and dariyan formations, 4 oil samples collected from reshadat and resalat oilfields were analyzed. physical properties of oils (e.g. the api gravity), indicates that dariyan oil in both resalat and reshadat oilfield is similar to (with low pour points and high sulfur contents) the oils from sarvak reservoir. ba...

Quantified balanced and restored crustal cross-sections across the NW Zagros Mountains are presented in this work integrating geological and geophysical local and global datasets. The balanced crustal cross-section reproduces the surficial folding and thrusting of the thick cover succession, including the near top of the Sarvak Formation (∼ 90 Ma) that forms the top of the restored crustal cros...

Sarvak Formation as the oil reservoir with the most hydrocarbon potential in Yaran oil field is of special importance. The present research was conducted to study the reservoir parameters of this Formation. For this purpose, petro-physical crude data was first prepared and using the Geolog6.7 software, a petro physical plot was drawn. Afterward, petro-physical properties of reservoir were done ...

In this research, the microbiostratigraphy and depositional environmental implications related to the Surgah Formation at the northern flank of the Kuh-e Sepid anticline in the Lorestan Basin are discussed. A study of small planktonic foraminifera from the 101-m-thick Surgah Formation led to the identification of three Turonian–Santonian biozones: (1) Helvetoglobotruncana helvitica, (2) Margino...

lurestan province is petroliferous area. the reserved oil are in ilam and sarvak  (cretaceous ) and kangan ( lower triassic ) and dalan (permian) formations. the lurestan area had high exploration activity but contribution of source rocks in hydrocarbon accumulations isn’t clear. in this paper essential elements and process of hydrocarbon accumulation are introduced. candidate  source  rocks ar...

In the Cenomanian, southern passive margin of Neotethys Ocean was dominated by a giant carbonate factory. This succession is known as Sarvak Formation, significant reservoir in Iran. study focuses on detailed analysis facies variations and paleoenvironmental reconstruction, including interpretation platform types, during this time interval. Based field observations petrographical studies, 12 ha...
