Symbolization of rock composition and structure in basin modeling

Abstract. The paper presents a comparative review of lithological pattern standards used abroad and in the Russian Federation. There is a difficulty in employing foreign standards in the graphical representation of basin modeling results. The author provides the main characteristics of the lithotype editor from the modeling software. The potential to customize visualization of the basin models was evaluated. The author describes the process of pattern adaptation from the standard of graphic arts for the State Geological Map (scale of 1 : 200,000) to all lithotypes included in the software library. It is proposed to use coloured lithological patterns to increase the informative value of the lithotype distribution model visualization. There are additionally defined patterns for the graphic representation of mixed lithotypes used in both conventional and unconventional petroleum systems. Software-adapted lithological patterns can be used both for constructing the simplest one-dimensional models of boreholes and for complex, continuously operating three-dimensional basin models. Illustrative differences between the adapted patterns from the standard of graphic arts for the State Geological Map (scale of 1 : 200,000) and standard software library serve as an example of visualizing a one-dimensional basin model for the Kola Superdeep Borehole.
