| The Asmari Formation (Oligo-Miocene) is the major oil reservoir in Iran, and is mainly composed of carbonate entities (Limestone and Dolomite). The Asmari Formation produces almost 85 percent of total Iranian crude oil and it is one of the main known reservoirs in the world. Therefore, the study of this rock unit has been a critical subject in the past and present time. This formation is well developed in the Zagros basin, southern Iran as well as in the Persian Gulf. It is believed that the Asmari Formation has a good fracturing system, which is resulted from the Red Sea opening and movement of Arabian Plate toward Iranian platform in the Neogene geological time. At the time being, these tectonic activities might be continued and create some seismicity and earthquakes in this area, affecting shortening strata in the edge of Arabian plate as well as the whole Zagros basin. One of the main products of this process is fractures. These fractures are very important in the Zagros basin for their effects in the production rate of Asmari reservoir (eg. Rag-e Sefid oilfield). The majority of studied wells of this oil-field have enough geological and petrophysical data. Among studied wells, eight of them have Formation Micro Scanner, FMS log data. The purpose of this paper is to find out relation between Curvature of Asmari Formation and fracturing system by using the FMS logs. Fortunately, this method resulted in a good conclusion, which can be applied for the Zagros basin especially, for Asmari Formation, having consistent with those of fracturing system in Kuh-e Khaviz, Kuh-e Pahn and Kuh-e Asmari | ||
