The Asmari Formation Revisited: Changed Stratigraphic Allocation and New Biozonation
Proceedings, 2009The essential biostratigraphy of the Asmari Formation was outlined in the early 1950’s and thereby the only published record of the biostratigraphy before the Asmari Formation was formally described in the mid 1960’s. The traditional Iranian biostratigraphy is based on unpublished reports.

Integrated Rock Typing in Asmari Formation of Gachsaran Field
Proceedings, 2009As part of an integrated reservoir modelling and simulation project, a rock-typing study has been performed on the carbonate Asmari Formation of Gachsaran Field (Iran). The current paper presents the challenges and results of integrating different disciplines in the definition of rock-types.

Comparison of Asmari, Pabdeh and Gurpi formation's fractures, derived from image log
Journal of Petroleum Science and Engineering, 2009Abstract Small scale fractures around the wellbore, strongly affect the hydrocarbon production. Identification of fracture plays a main role in production and development plans of oil fields. Image logs are one of the powerful tools in fracture study in wells. Image log is a high resolution “pseudo picture” of borehole wall.

The Pir-Sabz Section of the Asmari Formation is located in the Interior Fars province, Zagros Basin (Iran). The Asmari Formation at the study area is 312 m in thickness and formed by massive bedded limestone. According to the identified index microfossils, three Oligocene assemblage biozones were recorded: 1) Globigerina spp., 2) Lepidocyclina ...

Abstract The distributions of sediment grain types and microfacies in two outcrop sections in the central part of the Zagros Fold and Thrust Belt, Iran, are used to interpret changes in salinity during Late Oligocene (Chattian) to Early Miocene (Burdigalian) deposition of the Asmari Formation.

The present work is focused on the biostratigraphic analysis, paleoecological interpretations, and paleoenvironmental reconstruction of sediments of the Asmari Formation. The Asmari Formation, which is mainly composed of carbonates, has been studied in the Rig anticline in the Izeh zone, Zagros Basin, Iran.

An Overview of Oil Well Drilling Problems in Shale Formations (Case Study: Asmari Reservoir)
Geosciences and Engineering, 2021Shale layers are found in 75% of the drilled sections in Iran, which causes 90% of the problems of instability of wells, and this can cause a number of problems, such as complete or partial collapse of the well or even loss of the well before it reaches its goal.

Aboozar field is located approximately 72 km west of Khark Island in offshore Iran. Main reservoir of this field is an Oligo-Miocene stratum called Ghar which is a member of Asmari. Permeability plays important role in reservoir flow and always has much difficulty to be defined and modeled.

In the present research, biostratigraphy and paleoecology of the Asmari Formation at the Shajabil anticline, northwest Yasuj in the Izeh zone are discussed. The Asmari Formation at the studied area is Rupelian–Chattian to Burdigalian in age. In the study, 18 genera and 29 species of benthic foraminifera have been identified.
