Abstract: To solve the problem of incorrect horizons extraction caused by the low signal-to-noise
ratio of original seismic data sets, we present an anti-noise seismic horizon tracking algorithm, which
includes following steps. Firstly, use wavelet transform for de-noising and the calculation of dip angle
information. Then, estimate the initial tracking position based on the dip information. Experiments
show that horizon tracking results using our method match well with the geological horizons.

Key words: horizon extraction, seismic interpretation, coherence technique, wavelet transform
