Abstract

Several seismic attributes were used in analyzing 3D seismic data of Kupe Field, New Zealand to study the structural pattern especially the faults and fractures. The size of 3D seismic block volume used in this study is approximately 37 Km x 15 Km x 5 Km consisting of 288 inline and 736 crossline seismic sections. A Kingdom computer software was used in the interpretation. The attributes were used to improve the presence of horizontal faults in the time slice. In this paper, a time slice of 0.6s was used to test the application of the attributes. A total of 6 different attributes including amplitude, dip of maximum similarity, maximum curvature, minimum curvature, most positive curvature and most negative curvature were applied at the chosen time slice. A total of 20 normal faults (F1to F20) were identified in the 2D seismic section of inline 549 and these faults were well correlated laterally in the time slice of all applied seismic attributes especially in the most negative and minimum curvature seismic attributes. A total of 238 horizontal faults and fractures were identified in the time slice representing Giant Foresets Formation of late Pliocene in age. All the measured faults and fractures trend were plotted in the rose diagram. The major trend of the fault is N30°E to N40°E or NE - SW.
