Discovered hydrocarbon deposits in a number of fields are the characteristic of the industrial productivity of Jurassic sediments in the north of Western Siberia. Most of the deposits are in the Middle Jurassic sediments, the signs of hydrocarbons have been obtained in the Lower Jurassic sediments, single deposits have been obtained in the Upper Jurassic sediments. This uneven distribution of deposits in the Jurassic oil and gas bearing facility is associated with the complexity of its structure. Therefore, there is a need to conduct a comprehensive analysis of the geological structure of Jurassic sediments, to identify geological parameters to predict commercial oiland-gas content zones in the investigated territory. Based on the results of the study of deep drilling data, seismic survey in the north of Western Siberia, schematic maps of the depth zones of Jurassic sediments have been constructed, the author of the article determines the parameters of industrial productivity zones. The most significant parameter is abnormally high formation pressure. Based on the conducted researches, the author notes the prospective commercial oil-and-gas content zones for Jurassic sediments within NadymPur watershed.
