Abstract
Traditional approach to predict reservoir properties involves map construction of the expected net thicknesses and porosity on the base of dynamic attribute analysis of the wave field and inversion results. The reservoir permeability is an important parameter for field development, its forecast on the base of seismic data is not widely spread, although there are publications that illustrate the possibility of such forecast. The article presents the results of applying the frequency-dependent seismic attribute MOBATR, which characterizes the relative changes in the permeability of the reservoir. This attribute aimed at detecting frequency anomalies in the spectrum of the wave group, reflected from porous fractured reservoir. In accordance with the analytical solution, on which based the calculation of the attribute, its values change indicates on the proportional change in permeability along the reflector
