The classification of non-structural traps is based on genetic and morphological features, which are used to distinguish lithological, stratigraphic, or tectonic types. When identifying types of non-structural traps at the first stage of exploration, less expensive geological and geophysical methods (magneto-and gravimetric), as compared to traditional seismic surveys, as well as paleoreconstructions, play an increasingly important role. In Western Siberia, there is a large variety of non-structural traps, but lithologically limited ones prevail. In addition, in Western Siberia, alluvial deposits were found in deep-water turbidite deposits, not on structures, but between them. The estimation of Jurassic and lower Cretaceous resources by the D1 category is given.
