Abstract :

In this study, we tried to dentify the fractures and faults of Khaviz Anticline, north of Behbahan, by using the ETM+ satellite images and the Digital Elevation Model (DEM) in the ENVI 4.8 and Arc GIS software environments. Therefore, the lineaments were identified using the linear filters in different directions and the hillShade map constructed from the DEM. Subsequently, the lineaments were compared with the constructed band combinations and the geological map to separate the fractures and faults. Based on the findings, the dominant direction of the fractures and faults follow the northwest-southeast (NW-SE) trend along Khaviz Anticline. Assessment the ISODENSITY map of the faults and fractures indicates that there is the utmost accumulation of the fault and fractures is in the south limb of Khaviz Anticline, Then by considering the important role of fractures and faults in migration of hydrocarbons, the southern flank of this anticline can acts as a suitable area for accumulation of hydrocarbons
