This study utilized some common seismic attributes that are of appreciative value to the information acquired through accustomed methods of seismic interpretation. The seismic attributes extracted and analyzed have been shown to provide new information and insights into structural mapping. The use of signal processing, edge detection, structural smoothening, median filter, sweetness, relative acoustic impedance and semblance attributes help to enhance seismic reflector, continuity and interpretation of fault network in the study area. They further assisted greatly in delineation of hydrocarbon leads. The use of envelop, frequency and root mean square (RMS) attributes subsequently helped to reduce exploration and development risk.
