The features of seismic inversion methods are applied in west siberia
(Kondratiev I.K. Bondarenko M.T. Godin Ju.Yu. Reygass E.V. Tarasenko E.M. )
The different ways of seismic inversion are employed depend on geological conditions. When thickness of target beds, containing a set of sandstone interlayers, is large (> 12 m), it is possible to use acoustic impedances Ip and time thicknesses of bed AT from impedance cubes. For thin beds only values Ip can be used. Nevertheless even in this case acoustic inversion succeeds to separate the clay and sandstone zones with weak acoustic differentiation.......
