Interwell seismotomographics for solving of the engineering-and-geological problems and its perspectives in oil/gas geology

Let’s consider the experience of the interwell seismic tomography application for the engineeringand-<br>geological problem solving referring to the physical state of a rock block, study of the geologic-andtectonic<br>structure, karsting, etc. while investigating of the projected and constructed metro tracks in Ekaterinburg,<br>Chelyabinsk, Ufa, Kazan as well as at constructing of Yumanguzinsk hydro-junction.<br>On a base of the theoretical and experimental downhole surveys in Bashkortostan oil/gas fields, the<br>restrictions and the perspectives of a seismic tomography method were demonstrated for studying in details<br>of the pay horizon structures in the interwell space.
