Key words: seismic inversion, forward modeling, petrophysical study.
Recently, a tendency of state-of-the-art technologies designed for prediction of HC reservoir properties basing on seismic and well log data to fail producing the expected results has been observed. This may be due to a number of objectively reasonable causes, namely, complexity of seismic and geological characteristics, reservoir is not enough contrast in terms of elastic properties, and insufficiency of input geological and geophysical information. This paper discusses the questions of seismic inversion feasibility assessment in the stage of planning a work and setting a problem. Before carrying out inversion transformations, the integrated performance of such procedures as seismic data quality assessment, petrophysical substantiation of seismic inversion, and forward modeling is recommended. All this will allow to eliminate unreasonable time and financial costs.
