Abstract
Introduction. This paper discusses the application of forward stratigraphic modeling as part of an exploration program development. Geological process modeling is aimed at reconstructing reservoir architecture through algorithms that simulate natural processes. The results provided make it possible to evaluate different variants of lithology distribution of the Achimov formation and predict zones of development of promising oil and gas deposits in areas that are not well explored.
Aim. The aim of the work is to predict the distribution of potentially promising objects confined to lithological traps.
Materials and methods. One parametric well and one exploratory well have been drilled in the area under consideration, and the work area has also been covered by 2D seismic exploration. In this work, forward stratigraphic modeling of deep-water floor fans and landslide complexes of the Achimov formation in one of the areas of the Western Siberian oil and gas province was carried out.
Results. As a result of modeling, it was possible to determine the sources of sediment transport and sources of deposition, and to map the boundaries of landslide objects and deep-sea floor fans.
Conclusions. Creation of dynamic models reflecting the processes of formation of deposits is a relevant tool to improve the understanding of the formation of oil and gas traps. Implementation of the new algorithm can improve the reliability of geological models and open new opportunities for hydrocarbon field discovery.
