Key words: permeability, well test, production data, sedimentological model.

Approach to permeability maps construction is presented on the base of well tests results taking into account conceptual geological model. It is shown that creating of permeability map should be based on the all available data from the sedimentological features of the reservoir formation to the results of seismic surveys, core analysis, results of well testing. Predictive ability of the obtained maps can be enhanced by the use of interpolation and smoothing algorithm based on the sedimentological model.
