Abstract
The article is devoted to the assessment of the Q-factor of the medium using model seismic data. Investigations include the brief overview of seismic modeling software that allows modeling the wave field accounts Q-factor. The comparison of results obtained with Q-calculating algorithms and model seismic data with different signal to noise ratio gives a real estimate of the error in determining of Q-factor. This fact can be taken into account in the time processing of the real seismic data.
