    In the study area of Duza Wolka, 3D a seismic survey was carried out, and in the center of this area Vertical Seismic Profiling in the hole S - 421A was taken. The seismic data received from Zechstein interval are characterized by low frequencies. This is caused by attenuation tracks of Triassic rocks. Vertical Seismic Profiling, namely the registered downgoing wave, allows to determine attenuation characteristics of the medium. Based on the analysis of downgoing wave, Q factor for each layer was estimated and then Q inverse filter for the two seismic profiles was applied, these profiles crossing well S – 421A was selected from 3D seismic survey. The aim of inversion application was to improve seismic data quality, especially timewindow (750 – 1300 ms). Improving of seismic data quality based on the vertical resolution increasing. In this case better resolution may be obtained by increasing the amplitude spectrum in high frequencies pass.
