|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
