Principles of seismology is based on the seismic (elastic) wave propagation in elastic environment. These waves are attenuated as they are propagated. Attenuation of the waves is a function of frequency and causes declining both in amplitude and frequency. This reduces the quality of seismic section. Disregarding the seismic wave attenuation affects processing and interpretation of seismic data. Absorption phenomenon is a major factor in seismic wave attenuation. This research introduces three methods to develop linear filters for omission of seismic wave absorption through inverse Q filtering method. The filter can be designed in a variety of ways, in this study we investigated Wang, Hale and PSO methods. Hale method directly uses inverted Q filter and a mate matrix, PSO method uses pseudodifferntial operators and isn't effective in all situations and Vang method is based on principles of wave propogation. In the latter method inverse Q filter and deconvolution function exactly as wave propogation. The results indicated that the Hale method responds well to all Q values used, but the PSO method responds well to the Q values more than 40. Using these methods, it is possible to reduce the absorption effect up to a great extent and sometimes omit it completely. According to the results, it is better to remove noises from seismic data as much as possible before applying inverse Q filter.
