Western Siberia is the largest oil and gas basin, which occupies one of the main places in the fuel and energy complex of the Russian Federation. Novoportovskoe is the first hydrocarbon field discovered on the Yamal Peninsula. The presence of significant oil and gas reserves here was proven back in 1964, when a powerful gas fountain with a daily flow rate of more than 1 million m3 flowed from the R-50 well in the Novoportovskaya area of the Yamal Peninsula. This work is devoted to the construction of a seismogeological model, a detailed consideration of the geological structure of the Paleozoic-Mesozoic complex and the oil and gas potential of the Novoportovskoe field. The results of the structural-tectonic analysis showed that the Novoportovsky swell stands out in the reliefs of all reference levels, upsection slightly changes its spatial position and parameters. During the Jurassic stage of development, the Novoportovsky swell had not yet formed, the western part was uplifted, forming a monocline from west to east. In the Berriasian-Lower Aptian stage of development, the central part of the swell tended to grow, forming a single structure. In the Aptian-Cenomanian period, subsidence occurred east of the central part, and the structure subsided. And only in the Turonian-Cenozoic time the swell was finally formed. In the section of the field, oil and gas content has been established in the depth interval of 470-3000 m from the Cenomanian to the Paleozoic.
