Structural Elements Detection in Seismic Data

Detecting discontinuities within seismic data is a constant concern, therefore a series of geometric attributes have been developed and used. Looking into semblance and coherency attributes led to development of new approaches to get insight on detecting discontinuities. In calculating such attributes usually are used discrete values of the amplitudes in the seismic data within a certain time window. Here we approach the calculations in a different manner, by detecting first the discrete values of corresponding phases and using the sums representing one phase for calculations and detecting discontinuities in the seismic data. There were used different calculations as to better view which is more appropriate, also considering the differences in data quality, some being more or less noisy or clear.
