Abstract
The study examines the facies and depositional settings for deep marine fans of the Lower Cretaceous (Neocomian) clinoforms in the southern part of the Frolov zone of Western Siberian basin. These strata demonstrate a complex geological structure in the study area: high heterogeneity of the facies, small size of sand bodies and uneven oil saturation, which affects the forecast and quality of reservoirs. Integrating methods seismic stratigraphy and seismic facies analysis helped solve one of the main problems, namely, to carry out facies typification of the Achimov deposits.
Materials and methods
In the article, based on the results of the analysis of wells (logging curves, core material, sampling) and seismic data, the geological models of the Achimov deposits were refined. The use of seismic stratigraphy, facies analysis and seismic facies analysis made it possible to identify promising objects.
