Abstract
The article systematizes the data and analyzes existing methods and published studies of non-anticline traps, often combined, which allowed us to recommend a set of works that are most effective in searching for traps of this
type in the Jurassic and Cretaceous deposits within the West Siberian oil and gas basin (NGB). The paper shows a number of diagnostic features of such traps and justifies a set of studies that allow purposefully identifying traps of a
combined type. An important condition for the successful implementation of the works is to conduct targeted research, building depositional models and paleogeographic reconstructions with the use of ichnofacial analysis. Delineation
and development of non-structural traps based on the proposed combination of methods can significantly extend the operational life of a number of “old” oil and gas producing areas, including Western Siberia.
