It is marked that quality and reliability of physical-geologic models directly depend on quantity of information available. It is shown that larger portion of such information can be obtained when solving inverse problems of seismic exploration, where a special position is held by inversion transformations allowing interference effects to be reduced, structural mapping to be updated, distribution of properties between wells to be predicted. Example of attracting acoustic inversion transformations to identify a new target for study is presented. Parameters distribution prediction maps are constructed.
