| description | It has been done a study to detect fault on 3D seismic data in Bass Basin,
Australia based on seismic attributes of crosscorrelation, semblance, and
eigenstructure coherency. These attributes measure similarity of adjacent traces.
There is a low coherency values on 3D seismic data on the detected fault. The
geologic structure such as fault (dip-slip fault) system can be detected by
calculating the seismic attributes coherency. The results of the analysis show that
the seismic attributes of crosscorrelation, semblance, and eigenstructure
coherency can be applied to detect continuity of fault on 3D seismic data in Bass
Basin well which it can distinguish between the values of high coherence
approximately 0.8 to 1 and low coherence values around 0 to 0.5. The use of
attributes can help identify the continuity of fault. The increase of the continuity of
fault on vertically seismic section and time slice seismic section is recognized
plainly, so the fault can be indentified clearly too. Based on this research, the
crosscorrelation-based coherence has the fastest calculation which it is about two
times faster, semblance-based coherence using analytical signal has the best
result as demonstrated by low coherence values are around 0 to 0.5 associated
with geometric shapes of fault which it most clearly visible than the other
attributes of coherence, and fault�s orientation in the study location is northwestsoutheast. |
