The various faults that hit the Tanak area were identified by studying the seismic sections in several directions and with specific exclusions, and intensifying those exclusions to increase their accuracy of clarity by using the most appropriate types of seismic attribute maps for the 3D survey (Edge Enhancement map - Artificial Illumination map - Azimuth map - Dip map - Seismic Amplitude map - Polarity map - Frequency map) for accurate check of these faults and cracks in the studied area especially for Al- Rutbah formation. We found helpful and supportive indicators in order to determine its optimal location by applying previous seismic maps on its seismic surface. These maps were compared with each other after being exported to the Petrel program besides the time map of the study area. As a result, the fault boundaries were determined as accurately as possible by using the programs: (Geoframe - Petrel -Word).
