The depth structure and rocks composition of Eastern part of the Russian platform have been investigated in the high grade. Within this territories hundreds petroleum and gas fields were in exploitation. For their exploration the different types of geophysical and geological methods were applied. These data allows consider and evaluate their effectiveness as well as theoretical base. The data shows that the postulates of organic petroleum and gas genesis paradigm dominating in the petroleum geology and teaching of the students in universities all over the world are not in line with real modern data and information. The history of petroleum exploration works within that territories demonstrate full independency of dominated model of petroleum genesis from methodology and strategy of petroleum exploration. It substantiated that the search for the petroleum accumulations depends on the withdrawal of two uncertainties. First is static one and it composed by the trap, reservoir, shield and canal of petroleum migration. Their location is the uncertainty. Currently it declining by 3D seismic survey methods. Second is dynamic uncertainty dealing with discrete process of petroleum hydrocarbon molecules formation. This process could not be expressed by exact mathematical means, but could be determined approximately applying the mathematical theory of fuzzy sets with very high grade of the approach to the petroleum accumulation existence.
