Due to small scale fracturing and the impossibility of locating their traces in seismic section .It is not feasible to detect this fractures even using mud loss information out of well log data . Also because of lower core recovery in fractured zones and expensive costs associated with core drilling it is logic to use high resolution imaging logs taken out of well in evaluate oil reservoirs. The new inhole imaging technology using spatial instrument in carbonate with spectral interpreting skims. We may achieve up to 5 mm spatial resolution which in comparison with other well log data having up to two- three feet, spatial resolution. It is possible to use this technology to detection the structural, textural and secondary porosity .In fact the application of this new imaging technique is increasing susceptibility the conventional described of core data. These interpreted images are appropriate susceptibility for accessing structural and geometrical parameter of fractured zones where core recovery is normally low. Fractured carbonated reservoirs which are famous universally are the main source of oil and gas production. The studied oil field in current thesis that is located in the Zagros zone, near Dezful and we have used information data from a well with 250 meters depth. The main information with great extension in Dezful region is Asmari which is petrology contain fractured carbonate rocks with standard origins. We have used FMI imager logs with a good coverage and resolution to detect fractured systems in the above well. After processing image data different open, close, inductive and breakout fractured zone were determined. Evaluating the results suggest that in different depths the type of fractured may be closed with lower permeability and other depths we may find open fracture with high permeability and conductivity. At the end we conclude that the older fractures have been developed in 4 structural direction corresponding Zagros trust deformation mechanism folded by newer inductive and breakout fractures resulted from drilling stress development.
