The territory of Northern Ustyurt, which has a complex geological structure, has long attracted the attention of researchers. In recent years, a significant amount of seismic exploration work, both 2D and 3D, has been carried out on the territory of Northern Ustyurt. Structural constructions were made for target reflecting horizons and the geological structure of the studied areas for the Paleogene-Triassic sediment complexes was studied quite fully. The Shagyrly-Shomyshty gas field is located within the North Ustyurt Depression, the northwestern marginal zone of the Kosbulak trough, was discovered in 1959. In 2015 the field was put into industrial development. At the early stages of development of the Shagyrly-Shomyshty deposit, it was believed that it was confined to an anticline fold with four pronounced arches. However, based on the results of geological and geophysical work carried out to date, a completely different conceptual view of the geological structure of the deposits has been proposed and substantiated. This became possible due to the use, along with structural, of dynamic interpretation of seismic data, the purpose of which is to predict reservoir properties and fluid saturation of the host rocks. The article presents the results of dynamic interpretation of seismic data, which allowed for a more detailed study of the structure, the creation of a substantiated geological model and recommendations for further development of the field.
