Static Digital Modelling of Stratified Geological Objects: Technological Applications

In modern multi-purpose information systems supporting all aspects of geological activities, including the use and protection of the geological environment, structural-lithological modelling plays an increasingly significant role. However, modelling layered sedimentary objects with complicated stratification remains a complex task requiring a specialised approach. This paper proposes a statistical method for modelling the lithology of sedimentary strata based on non-stationary Markov matrices using lithological sections from wells. The model developed according to this principle synthesises the most probable lithological section at any given point, providing sufficiently accurate interval estimates of parameters for detailed object mapping and differentiated assessment of its resources. This technology has been implemented in a GIS environment and has been successfully tested on real geological objects.
